If the hunting is not just fun for you, then to the process of choosing a sight you need to come with responsibility and knowledge of the case. From how much exactly you shoot depends not only your prey, but maybe your life! Sight - an integral part of the gun. What you have: an optical sight, a collimator, a laser target designator or a simple flies - not important. The main thing is that with the help of this sight you shot exactly. Your sight must be to the place. If you are driving a corrugated hunt, you do not need to take 20x multiple optical sight. If you have a super perfect carbine with a sight distance of 400 meters, then you do not need to put a simple collimator sight on it. If you have an ordinary double-barrel - do not install the most advanced night sights or a supest optical sight. Come to this case with your head and everything will turn out.

Night devices
Human vision is far from the best indicator in comparison with other alive species, for example, in comparison with the cat. Our eye perceives a certain spectrum of the rays and has certain photosensitivity, which limits our visual abilities in the dark. Optics specialists have long been looking for a solution to this problem at the technical level and, finally, found. As known, night devices Initially developed for military purposes, for army units. In addition, the initial purpose night devices - This is the detection of the enemy in conditions of poor visibility, namely in the dark time. First night devices have quite massive dimensions, and they weighed a lot, they could not be used as a mobile, wearable device, unlike modern night devices. Such night devices installed on the tower machine-gun installations and were used as trew night vision.
Earlier night vision sights We worked on the basis of the reflection of infrared light from the source, for this, a spotlight was installed on the combat vehicle having a red glow. This technology is far from excellence and has a number of serious deficiencies, take, for example, an elementary failure of the searchlight and everything is susceptible to trew night vision will not be. And a completely different thing is with the products of this kind in our time.
Well, first, now night-vision devices available in free sale, which before determining could not be, and secondly, the principle of operation night vision devices And their mobility stepped far forward compared to the first samples. Modern night-vision device - This is mobility, ease of handling, reliability! The only obstacle to the acquisition of such an appliance is the price, unfortunately, the domestic industry in terms of production night vision devices It is far from the first place, therefore mainly foreign samples prevail in this market. By itself, the device is specific, as far from every person there is a need to observe something or someone in the dusk of the night. For civilians night-vision devices - This is a privilege, first of all, hunters. There is no doubt that any hunter who goes to the night hunting dreams to have such a device at least as an observational means, not to mention sight of night vision, Which can be installed on the rifle.
To the easiest, and, accordingly, and cheap night vision devices You can attribute a monocular night vision. Monocular night vision is a device similar to binoculars having one prizir. These devices have a difference only in the multiplicity of zoom, as the basis is, of course, optics. A monocular cannot be called a comfortable device, although it is already determining the user, it suits it such a product or not.
The following device, which can be attributed to the same form, is a night vision binoculars, which, unlike monocle, has two viziers, which is much more convenient when applying. In addition, another equally well-known night vision device is a visual trumpet. The advantage of the visual tube in front of the monochal and binoculars is the multiplicity of the increase. In the visual pipes, as a rule, very good optical lenses are installed. As for the price of visual pipes, there is nothing to boast, the price at the binoculars level, and is often much more expensive than the night vision binoculars. The above night-vision devices can be attributed to one class. In popularity, they use not only in hunters, more and more they are acquired by various security structures, whose activities are related to round-the-clock protection of various objects, which, unfortunately, do not always have a good lighting in mind the specifics of their location.
It is impossible not to remember here another device called optical Night Vision Sightwhich has in its set of features not only the function of detection and observation, but also aiming, which makes the device universal in its class. Optical Night vision sightsuntil recently, it was used exclusively in special army units and were established (and installed) on sniper rifles. The modern range of hunting weapons is so diverse, which allows you to install. optical Night Vision Sights On some types of hunting carbines. Known to all hunters (and not only) saiga carabiner as it is impossible to fit under night sight. With such a "tuning", the rifle is not particularly different from the sniper, in connection with which the question of prohibiting use optical sights During hunting. Based on the fact that such a weapon does not leave the beast chance of survival, it is already hard to underestimate superiority trew night vision. As for their classification, they do not have any particular differences, with the exception of the increase in the increase, which is characteristic of almost all optical instruments. Prices night vision sights Pretty high, but according to statistics it does not affect the desire of hunters to acquire such a "toy".
To new markets night vision devices You can attribute night vision points. It is premature to talk about the efficiency and usefulness of such glasses, since this is a new technology and as any new invention, most likely, has its own flaws. In general, before purchasing night vision devices It should be guided, first of all, the goal that is planned to be achieved, and it is also necessary to pay attention to the technical characteristics on which it depends on how the device will meet your expectations.
When operating night vision devices Be sure to follow all the requirements prescribed by the instruction manual and maintenance, this will increase the service life of the device. In no case should not allow mechanical damage that may affect either the integrity of the lenses, or on their position in the frame night vision device.
Colimator sights
Not any person knows the meaning of the word "collimator", but, for sure, everyone saw from the screens of televisions the principle of operation of the collimator trance. This is nothing more than, the so-called "red point on the forehead". Colimator sights Used almost with any kind of modern small arms - from a pistol to a sniper rifle. Colimator sights, like any electrical product, have their drawbacks and advantages. The main goal in the manufacture of such sights was delivered to employees of the enterprise to develop systems of targeting fire, quick and accurate guidance of weapons, aiming in conditions of limited visibility. Mostly colimator sights Apply to targeting on target with minor distances and good weather conditions when the target is mobile, or when there is no time for a very accurate shot. Principle of operation colimator tar.based on the supply of electric power (battery) on the source of light radiation (often the manufacturers use the LED), after which the light beam, passing through the lenses, forms a light beam, as a result of which the arrows and sees the "marker". Markers have a different form: it can be both a circle and a rhombus, as well as a triangle, crossbar, grid.
So, about flaws. Collimatic sightsthere are batteries that periodically change, besides, it is worthwhile to take into account the conditions of operation of the device, there is no existence of moisture sources, although, according to manufacturers, the sights are waterproof, but no one does not give a 100% warranty from the installation of electrocups. The following drawback is self-repaid, which is extremely unpleasant and negative indicator when conducting hostilities and carrying out military operations.
To the advantages colimator sights There is a high speed of targeting the target and the ability to continually hold a mobile goal in the shooting sector. Colimator sights Have a narrow use of sniper weapons. It is connected again with flaws in terms of self-exchange. The sniper must be out of sight of the enemy, and the light sources of the sight are driven by an arrow to zero, and to mask them simply meaningless. Quamator sniper sights have a number of differences from ordinary quimatory sights. The main difference is the presence of the most optical sight, which has the backlight of the aiming scale, which significantly improves the quality of the firing due to the difference in the contrast of the light balance of the target and the sighting scale. In this case, the arrow task for the implementation of an accurate shot is to combine the sighting scale in an optical sight with a marker for the target. On shotgun, quimator sights are used mainly with a marker in the form of a mesh, since the shot with a fraction has an extensive lesion area at short distances.
Colimator sights Also found their place in certain circles of civilians who include hunters and fans of pool shooting. Colimator sights There are mechanisms for adjusting a marker, and in the case of a sniper sight - also a number of settings that are regulated by the manufacturer's plant. To properly configure the action, a form is used, or an instruction manual (depending on the device output form).
What is pararallax?
In conversations "experienced" when it comes to optical sights, often "pops up" the concept of "pararallax". At the same time, many firms and models of sights are mentioned, and a variety of estimates sound.
So what is Pararallax?
Pararallax call the visible shift of the image of the target in relation to the image of the sighting mark, if the eye moves away from the center of the eyepiece. This is due to the fact that the purpose of the target is focused not quite in the focal plane of the aiming brand.
The maximum parallax occurs when the eye reaches the boundary of the output pupil of the sight. But even in this case, the sight with a constant increase in the increase of 4x, rebuilt from parallax 150 m (at the factory) will give an error of about 20 mm at a distance of 500 m.
At short distances, the effect of parallax practically does not affect the accuracy of the shot. So for the above mentioned above, 100 m error will be only about 5 mm. It should also be borne in mind that when holding the eye in the center of the eyepiece (on the optical axis of the sight), the parallax effect is practically absent and does not affect the accuracy of firing in most hunting situations.
Sights with factory detuning from parallax
Any sight with a fixed lens focus system can be disposed of pararallax only on any one specific distance. Most sights have a factory detuning from pararallax per 100-150 m.
The exceptions are the sights of low multiplicity of increasing focused on use with a shotgun or combined weapon (40-70 m) and the so-called "tactical" and similar sights for shooting on distances (300 m or more).
According to experts, it is not necessary to pay serious attention to Paralylaks, provided that the shooting distance extends within: 1/3 closer ... by 2/3, on the distance of the factory detuning from Parallax.
Example: "Tactical" Sight Kahles ZF 95 10x42 rebuilt from parallax at a distance of 300 m. This means that when shooting at distances from 200 to 500 m You do not feel the effect of parallax. In addition, when shooting 500 meters, the accuracy of the shot is affected by the mass of factors associated, first of all, with the characteristics of weapons, ballistics of ammunition, weather conditions, the stability of the weapon position at the time of aiming and shot, leading to the deviation of the point of entering the aiming point on Values, significantly exceeding the deviation caused by pararallax when shooting from a rifle, squeezed into vice in an absolute vacuum.
Another criterion: parallax is not manifested in a significant way until the multiplicity of the increase exceeds 12x. Another thing - sights for target shooting and warring, as, say, 6-24x44 or 8-40x56.
Sights with the possibility of tuning from parallax
Target shooting and warming requires maximum aiming accuracy. To ensure the required accuracy at different shooting distances, sightsets are produced with additional focusing on the lens, eyepiece or on the center tube housing and the corresponding distance scale. This focus system allows you to combine the object of the target and the image of the aiming brand in one focal plane.
To eliminate parallax at the selected distance, you must do the following:
1. The image of the aiming brand must be clear. This must be achieved using the focusing mechanism of your sight (dioptime correction).
2. In any way, measure the distance to the target. By turning the focusing ring on a lens or flywheel on the center of the center tube, set the measured distance from the corresponding tag.
3. Securely fix the weapon in the maximum stable position and look at the sight, concentrating on the center of the aiming brand. Lightly lift, and then lower your head. The center of the aiming brand must be absolutely immobile with respect to the target. Otherwise, perform an additional focus, rotating the ring or drum until it eliminates the movement of the brand's center.
The advantage of the parallax tuning sights on the central tube housing or on the eyepiece is that when tuning the arrow, which prepared for the shooting, there is no need to change the position.
Instead of output
Nothing is just like that. The appearance in the target of an additional adjustment unit may not affect the overall reliability of the structure, but with the proper execution - at the price. In addition, the emergence of the need to think about the additional configuration in the stressful situation cannot but affect the accuracy of your shot, and then you will be blamed in the miss yourself and not your sight.
The above values \u200b\u200bare taken from materials provided by LEUPOLD (USA) and Kahles (Austria).
The situation with hunting weapons in Russia and most CIS countries is exactly the opposite of the one that is now with a short-barreled weapon for self-defense. If a normal pistol is also available for ordinary citizens, and for professional shooters only on rifle objects, then with long-life weapons everything is somewhat better. Everyone who wants, if he, of course, has time, money, as well as the ability to overcome bureaucratic obstacles, can acquire at least a smooth-bore rifle, at least a tactical shotgun, and with a rifle carbine or rifle. And train with them in your pleasure. And here it is very often the question arises - and what sighting devices to use? Mechanical sight, collimator or optics? The question is good. And we will try to figure it out now.
Open Sight
Mechanical sighting devices There is in the basic configuration of almost every weapon. Therefore, it is recommended to start familiarizing with weapons and shooting from "Mechanics" - if it turns out to quickly combine the culk with a fiber and bring the resulting targeted line to the target - everything else will be mastered quite simply. Although, in principle, the average distances of the open sight is enough.
There are still disadvantages - the culk and the fleece completely overlap the sighting picture in the lower hemisphere, which does not play in the hand at - it comes longer to aim, leading the barrel to find the target. The proposed solution is to establish a dioptric scope, the situation with it is a little better, but there is a "jokes".
Among other things, to make amendments to mushrooms of some structures is quite difficult - a special tool is required. Or you have to make a mental amendment, which is much more complicated. Of the advantages, it is worth noting simplicity, versatility and the smallest price of a mechanical sight of all aiming devices.
Colimator / Holographic Sight
They say that with colimator sight , Mall-de, brought the red point to the target and only know that click on the trigger. However, as practice shows, only every third newcomer is quite quickly mastered and begins to effectively affect the goals (although with the collimator, it is still easier to shoot than with a mechanical open sight).
Therefore, the collimator is not a means of inability, but a good addition for the experienced arrow, it will help, in the dark, from uncomfortable provisions, with. They also say that the collimator is not subject to pararallax. No matter how it is as pronounced! And the inexperienced arrows can easily shoot "in milk".
The cost of high-quality modern collimators is quite high. There are, of course, cheap Chinese models that are often used in military-tactical games of the strikeball type. But on firearms, such aiming devices can simply fall apart. At a minimum, the sighting mark after the shot is knocked aside.
Holographic sight It differs from the collimator to another way of formation of aiming brand, visible arrow. As it is clear from the title, this is done using a hologram. Such sights are obtained more compact, they have, due to higher requirements for the manufacturing process, there is much less parallax effect, so they are significantly more expensive than collimators. Another plus - the holographic sight is perfect for.
One of the main advantages and collimator, and the holographic sight is the ability to lead an accurate shooting with two open eyes. The brain is much easier to handle the sighting picture obtained from two eyes, with the imposition of aiming brand visible only with one eye.
Also, a separate advantage is the fact that the collimator and holographic sight is perfectly combined with the magnifier (magnifier), which is placed on a single line with the main sight, and simply leans on a special bracket if you need shooting short and average distances.
All the same, such a design is obtained cheaper than a full optical sight.
Optical sight
So, good and modern (read - reliable and high-quality) optics are much more expensive than all previous options. At the same time, an optical sight with variable multiplication from 1.5 to 6 at a minimum increase completely replaces the collimator, and at the maximum - allows you to shoot further and more accurate than the same collimator with a lot.
Came through optics for long distances with two eyes is difficult. And close one eye - it means to limit the space of the review by escaping it to the size of the sight. What is dangerous in real combat conditions, but in sports - it is simply fraught with a small loss of time.
There is an opinion that an optical sight is fragile, therefore it requires particularly promotion. In contrast, for example, from the same mechanics for which at least a hammer of knocks - nothing will not change. So, this is a question again. Top models of expensive optics, you can though nails score. And simple models, yes, require care and careful relationship.
It is also worth considering that optics - exactly what you need people with poor eyesight, because it allows you to adjust the parameters for your own needs. Another point is the weapon tab. Considering the closely close arrangement of an optical arrow to the eye, it is possible to be easily used to drive the fiction. Therefore, the experience of handing arms plays an important role - the optics is definitely not suitable for beginners.
However, this is all applicable for carbine or rifle, but if you have a shotgun, the optics are definitely not needed. Maximum targeted range when shooting a special bullet from a smooth barrel - about 100 meters. Here and simply the collimator will be more than enough.
Summarizing: What are the sighting devices to choose?
Optical sight It is necessary for from the rifle carbine or rifle, but strongly narrows the field of view, it does not allow to aim quickly, it takes up a better weighing weapon. A modern optical sight with variable multiplicity is ideal for high-income civilian shooters, it will affect the target on loved ones, medium and long distances.
Collimator or holographic sight - Option for experienced shooters and employees of special forces, because the aiming is noticeably accelerating and expanding the capabilities of the arrow.
Mechanical open sight - The basic option from which everyone needs to start.
But if a person in principle trained a little and does not know how to treat a weapon, then no sighting devices will help him.
Many hunters, acquiring a smooth-bore rifle, begin to think about how to tune it. The first thought is to install optics. But it seems to me, to install an optical sight on a smooth-bore rifle does not make sense, and that is why.
First, the shooting of a smooth-born rifle is carried out at relatively small distances (up to 50 m fraction, and up to 100-120 m balls). At such distances, any increase will be superfluous. Secondly, they shoot a shotgun most often offdck, and catch the goal, the more quickly moving, it will be very difficult.
What makes a collimator sight? Having a special optical scheme, the collimator allows you to replace the culk and the fly by one point. No longer need to combine three points, destroyed by eye: goal, fly and culk.
When do you need a collimator? Most appropriately apply a collimator sight when shooting at small distances up to 100 m, especially if the goal is quickly moved. This is a bird hunt, injection hunting, good francs, etc. Can a collimator sight replace optical? If short, then no.
Rather, the collimator sight replaces open aiming devices. Of all the above, it can be seen that the optimal increase is 1x. In addition, it is extremely desirable when shooting to look at the goal, which is called, both. No need to forget that most sights, even change of 1.2-4x20 or analogs, are quite large in size and weight.
So, it can be concluded that for installation on a smooth-born rifle, the most suitable are compact devices of small size and mass, which make it possible to shoot with two open eyes. Colimator sights are very close to the wording described. I look closely for them.
A shared line of all collimators is the lack of focusing (it is simply not needed) and the ability to arrange it at any distance from the eye of the arrow. Colimators can have interchangeable targeted marks, which makes it easier to aiming and entering the correction to the distance or control (in the case of a moving target). First of all, collimator sights can be divided into closed and open.
Closed Type Colimators (KZT)
KZT is a tube similar to an optical sight, the difference is that the KZT is much easier and more compact. More recently, it was possible to meet the "deaf" devices, looking in which, we are surprised to find that nothing is visible at all, except for one glowing point.
He worked as follows: throwing a gun, the arrows with one eye looked at the collimator and saw the point, another - on target. In the head, the image arrow was combined, and with proper guidance, the point was projected onto a target. Such instruments disappeared quite quickly from the sale, as they had a huge parallax and "turned off" one eye arrow, strongly limiting the review. Fortunately, they came to replace normal closed collimators.
KZT is smaller and easier than optical sights, but still quite cumbersome. But they have one advantage over the open collimators: at the same price, the closed collimator sight will be more abusive and protected. Also a big plus is the good visibility of the label at any lighting, even in a bright sunny day.
Open-type collimators (cat)
A cat is a small device on which the image of the aiming brand is projected into a small screen or lens. Cat can be both sufficiently massive and super-compact (literally with matchboxes). Open type collimators are most compact, practically do not reduce the review and, in my opinion, more aesthetic, although, of course, taste and color ...
The disadvantages include smaller service strength (mainly due to the lens) and the impairment of the brand's visibility during bright sunlight. A very interesting version of the cat is a holographic sight. Its main difference is the complete absence of parallax, the focusing of the aiming brand is in the plane of the target, the aiming brand itself can be any, including three-dimensional, shift of the aiming brand is carried out using a holographic screen shift.
A feature of a holographic sight is that the shot can be made when combining the aiming brand and goal, with an arbitrary position of the arrow or weapon.
Like an optical sight, any collimator after installation needs to be shot, for which they have drumming drums. For most tasks, especially on smooth-bore weapons, it suffices to combine the aiming line with a collimator label using a cold shooting device.
To install a collimator trance, it is necessary that the weapons are attended by landing places ("Lastochkin Tail", Weawer or other). It is important here to note that it is extremely desirable that the collimator is installed on a quick-consuming bracket and that the additional planks and response parts of the bracket are not blocked by the aiming slapting of the shot rifle. If neither twist, no matter how compact the collimator, he still strongly stands for the dimensions of the weapon, so it can be shot down or damaged when moving with a weapon, will be filled with water or sprinkle with dirt when the waterfowl game is hunting.
Another weak link in the collimator is nutrition. Most of them work on batteries, like open collimators that feed on small batteries-tablets are very sensitive to reduced temperatures.
First of all, it is necessary to determine the type of collimator. For shotguns and rifle rifles of large caliber, in my opinion, closed or open holographic collimators will be more suitable. For small-caliber rifles and caliber rifles up to 7.62x39 (and analogs), open collimators will be more suitable. After choosing a type of sight you need to know if the collimator fasteners are suitable for the database of your rifle.
The fact is that most of the closed collimators and all open have integrated brackets, and it will be changed subsequently impossible. On the collimator you choose must be adjusting the brightness of the aiming mark, and it is desirable that it be replaceable. In good collimators there are from 5 to 9 different tags.
A lot of collimator sights appeared on our market. There are very cheap models, from 15 cu, which can be delivered except for toys or light pneumatics.
When choosing a sight, it should be remembered that the collimator sight is exactly the sight, i.e. A rather complicated optical device. In addition, when shooting, it is experiencing large overload, so it can not be cheap.
At the end I would like to mention Chinese-made collimators. With a fairly low price, they can have very impressive characteristics. Often "on the eye" they are difficult to distinguish from the products of branded producers. Unfortunately, they have one very unpleasant drawback - unpredictable quality.
Almost all of them are well experiencing the return of small calibers (.22lr, 7.62x39, .223, etc.). But not everyone can withstand the return of a smooth-bore rifle, especially with the "Magnum" cartridges. Sometimes they just go out, but the sighting brand begins more often, which leads to inexplicable misses. Such a state of affairs makes you think about whether to save on the collimator and risk a long-awaited hunting.
The basis of the action of this type of sight is laid by the use of the principle of collimation of light, that is, the preparation of a parallel beam of rays that correspond to remote observation objects.
The collimator is a long-focus lens in which a brand is installed, highlighted by a special device. It has a point of a point diaphragm or grid with the necessary service information. For collimator sights installed on small arms, the brand is a diaphragm forming a luminous targeted point.
Colimator sights
There are closed and open types. All elements of closed collimator sights are located along the optical axis of the line of sight and when forming a point in the space, which is aiming, slightly limit the observation area. A collimator of open collimator sights is derived from the field of view the arrow and the formed aiming brand is projected on the observed space. All collimator sights have a one-time increase and unlimited takeaway of the pupil. True, a single increase limits the use of such sights at a direct shot. The size of the luminous target point in various sight is from one to fifteen angular minutes.
There are sights with a changing value of the sighting point, which is determined by the size of the target and distance.
In the collimator sight on the optical axis of the sight, a highlighted image of aiming brand is created - usually glowing point. Mark and purpose equally cutting. The main difference between the collimator sight from the optical is significantly larger diameter of the output pupil (20-30 mm) and its unlimited removal, which makes it possible to not particularly carefully, it is enough to simply combine the aiming brand with a view.
The designations of collimator sights are similar to the designations of permanent optical sights, for example, 1x20 - a single increase, the diameter of the input and output pupil is 20 mm. Although a single increase allows you to use the sight only on the range of direct shot, but the wide angle view - it should be at least 16 ° - allows you to shoot on moving purposes and aim with both open eyes using binocularity of vision. One eye of the shooter sharply sees a targeted brand and purpose, and the second eye - the surrounding space and the goal. This allows you to shoot with the absorption even in cases where the goal is not visible in sight of the sight (closed by the rim of the sight).
Open and closed collimator sights
By its design, collimator sights are divided into closed and open. Actually, the collimator is used to form an image of the aiming brand and consists of a illuminator (point light source), aiming brand (aperture with a hole in the center) and a focusing lens.
The closed collimator sight is very similar to optical, so it is well protected from external influences, usually has flywheels or adjustment buttons of the target brand position and mounted on standard brackets for optics. Since in closed sights, all elements of the collimation system are located along the optical axis of aiming, there is a partial shading of sight of the sight, to which light losses in several lenses are added.
In open sights, imprisoned in a thin frame, the lens is a lens or a glass plate installed under a slight tilt to the aiming line. The collimator is out of sight (usually at the base of the sight), and the image of the aiming brand is projected onto the lens, equipped with a reflective coating (meniscus), and on the other - transparent coating. Thus, in the field of view, the sight will be simultaneously visible the image of the target and the image of the aiming brand. Open-type sight is worse than closed protected from external atmospheric influences and mechanical damage, often has a specific attachment assembly, but it has a clear, not shaded field of view and low weight.
Like optical sight, collimatories also possess pararallax: in closed it manifests itself a little, and in open collimator targets can be very significant - the greater the stronger the eye the arrow is shifted from the optical axis sight. The smaller the focal length of the open sight, that is, the distance from the collimator to the lens, the greater the slope of the lenses and, it means more Paralylaks. Moreover, parallax is uneven: it is stronger when the eye shifts towards the opposite arrangement of the collimator. An open collimator sight for long-life weapons must have a focal length of at least 100 mm, and for a short-barre room - at least 50 mm. By analogy with the length of the aiming line in the mechanical sight, the collimator sight with a smaller focal length gives a greater error (deviation in aiming) when shooting for a long distance. Thus, the long-focus sight allows with sufficient accuracy to aim at a distance of up to 100 meters, short-focus - no more than 15 meters.
The magnitude of the parallax for the collimator sight is determined in the same way as for optical: the sight is fixed by the stationary and arrows, shifting the head to the right and up and up-down, whether the sighting mark is shifted with a relatively fixed target located on the selected distance.
The brightness of the brand should exceed the brightness of the target and the surround background at least 5-20 times. The color of the luminous aiming brand is usually red. In the simplest sight, the brightness of the brand can have only two values \u200b\u200b("day" - a strong glow, "night" - weak glow). In some sights, depending on the color of the target or the background of the arrows can choose the color of the brand (red or green). To highlight the brand in the field of view, it may flash with a frequency of 12-15 Hz or stepwise to change its brightness in the automatic (used photodetector) or manual mode at different levels of illumination. The visible size of the aiming brand can also be changed, which is useful if its size is equal to the diameter of the dissipation of bullets for a particular weapon. Nevertheless, the size of the aiming brand should not exceed 0.25-1 target size.
Aiming brand may have a point, crossing, cross-time crossing in the center, etc. The crossover with the gap is most practical, since the brand does not cover small or remote targets.
When choosing a collimator sight, it is necessary to pay attention to the elements of the design or control of the position of the aiming brand (flywheels or buttons) not limited to the field of view when aiming with both open eyes.
Some firms began to produce optical sights with a variable focal length of 1-4x, which, with a single magnification, use an optical sight as a collimator - using all the benefits of the latter, and with large zooms as optical.
There are other types of collimator sights. Some are based on fiber optic optics. They burn optical fibers placed on the optical axis of the sight. The upper part of the sight is open and the light assembled by the optical fiber causes a glow of the ends of the harness perceived by the shooter as a sight brand.
A similar system has a mechanical sight GLO-Point, developed jointly by Truglo and Daisy. In this system, multi-colored fiber, firmed on the fly and on both sides of the slot, forms three glowing points (one red and two green), well distinguishable even at twilight.
Further development of collimator sights has become holographic sight. By its design, he is similar to an open collimator sight. In sight, the arrow is a plane-parallel glass plate with a holographic image of aiming brand and other auxiliary information. In addition, in some speakers, the holographic image can perform the role of the reflector, as in the usual collimator target. The brand can be of any form, size and even three-dimensional, which allows you to create a brand represented as a luminous line aimed at target. Like a collimator, support radiation, falling on the plate, makes a visible image of aiming brand. Sometimes the point light source is mounted at the base of the device, but on the optical axis of the eyepiece.
The holographic sight is characterized by compactness and allows for a few seconds to replace the plate with a targeted brand to another, with a more suitable for these conditions for shooting the image of the brand.
However, a wide range of holographic sights is hampered by their significant price, relatively weak protected from external influences and such a feature, as the occurrence of color and geometric distortion of observed objects, if bright light sources fall into sight of the sight.
Advantages of collimator sights
Significantly simplify and accelerate the target process, since it is not necessary to level anything, only combine the brand and the goal, while the problem disappears the problem of different focusing of the eye on purpose and the brand, which is very relevant when using conventional aiming devices, where either the goal is visible vague, or a fly. Adding a whole more complicates aiming. This makes the CP especially attractive for persons who do not have greater shooting experience. The speed of aiming and the performance of firing when using the collimator increases markedly, it is especially noticeable for newbies.
Increase the accuracy of firing, especially in persons who are not having large preparation. Allowed to target weapons with a significant displacement of STP - the sights are adjusted in wide limits.
Corrects shortcomings of the rifle, balance, Pitch angle, etc.
Aiming brand does not cover the goal.
Allowed to produce aiming shooting in low light conditions, up to complete darkness, just to be visible. Better only night sight or special optics, but they have their own limitations.
Disadvantages of collimator sights
Increase the mass of weapons and change its balance (the last, truth, usually for the better), slightly, since the collimators are very notighted. With enough heavy weapons it is almost imperceptibly.
Nesh-sowes (140-150 USD Good domestic, 300-500 USD Good imported). Especially the holographic roads.
Beatability. Any optics requires a neat appeal, the prevention of protection against trash and periodic cleaning in compliance with the rules (cannot be finger). Clear collimators can wear transparent caps on both sides that protect the eyepiece and lens. They can be cleaned with a finger. Alas, lights, they, naturally, significantly reduce. Pollutability is especially relevant in winter, when literally step can not stand so that snow does not face the trees. Note that a developed visor in good open collimators (and not just a rim of the reflector) quite well protects the sight from clogging, at the same time allowing you to easily clean the sight. Open sights are also performed by hermetic, so there is no big advantage among closed type collimators.
Parallax. Any optical system in varying degrees has this phenomenon: if you take any optical or collimator sight, send it to any fixed target (better, of course, fasten it), and then, not a touching sight, move your head, i.e. look at the lens from different angles, then the sight will indicate different points on the goal, remaining fixed relative to it. In practice, this is a very unpleasant property of optics means that at different racks and ways to hold weapons, the weapon will be sacked in different points. Pararallax is peculiar to almost all the sights, cheap and expensive, and the only thing that can be done is to choose a sight whose relative error will be poorly, i.e. It will be within the desired shooting accuracy. Thus, when choosing optics, you should pay attention to how stably the position is taken by the head relative to the sight, and which mistake at the required distance will give us the usual movement of your head relative to the sight. Since during the archery of the crossbow, the distance is limited to 100 m, and a good sight at such a distance does not give a significant displacement, and the displacement variation is a consequence of other factors in not comparable. Pararallax good collimator 1-1.5 angular moments, i.e. 3-4.5 cm per 100 m, and with monotonous holding of weapons, it is zero, so when choosing a sight for a shotgun to Pararallax, you can not pay attention.
Alkaline batteries decreases at low temperatures. In winter, the sight is not recommended in the cold. Rationally in the winter period to wear a pair of spare batteries. Good sights have automatic brightness adjustment not only depending on the conditions of external illumination, but also on the degree of battery discharge, so the full digit of batteries does not occur suddenly, and will occur gradually, decrease the brightness of the aiming mark, which will allow the user to notice this in time and replace it in time and time Batteries. Lithium nutrition elements are significantly less sensitive to frost, so even on a strong frost (up to -35 s) they are enough for several days. In any case, a pair of spare battery packs are inexpensive and completely solve all the problems associated with the cold.
Holographic sights
American engineers once again improved the sighting system of small arms - a targeted brand replaced the hologram, manifested under the influence of laser radiation. The new holographic sight exceeds all previous analogues: mechanical, optical and collimator. Open targeted adaptations of the type of whole and flies morally and physically outdated and are kept on the modern arms rifle only because of the ease of use and reliability. Optical sights of naughty: they are more susceptible to shocks, dirt and dust, as well as very uncomfortable when shooting an off date.
Company EOTECH He stated that she was able to save a collimator sight from some of the shortcomings and began the production and sale of a series of holographic collimator sights. A large and transparent aiming brand, manifested under the influence of laser radiation, is well distinguishable at any illumination and is located in the center of the sight, regardless of the surveillance angle. She also does not overlap targets and does not distract the arrow. A glowing pupil is visible only an arrow and absolutely not noticeable even when using night vision instruments. In addition, this sight can be used in any weather - both in the rain, and in the snow, and with a strong fog. The sighting mark will be clearly visible even if the output window turns out to be broken.
It is worth noting that holographic sights are not only successful for sale around the world - they are interested in the top command of the US Sun US. After a short military testing, the limited batch of holographic collimator sights EOTECH was sent to Iraq and a small part of the instruments entered the US police.
