Any Questions? — FAQ
Why is my front lens bevelled?
All red dot sights have an objective lens at the front of the unit that is spherical in shape. However, unlike a conventional riflescope, the objective lens in a red dot sight is positioned off-axis and appears to be tilted when looking at the sight. The lens is tilted out of the direct optical axis in the x- and y-directions. This angle of the front lens allows the light to be reflected back into the sight. The reflected light becomes the “dot” or aiming reference that the user sees when a red dot sight is switched on. High-quality devices on the market are always recognizable by this feature. In addition, the bevelled lens reduces sun reflections that would otherwise betray the position of the shooter.
Blurred Reticle / Dot
There are many reasons the reticle / dot can look blurred or bloomed. The most common cause is focusing on the reticle. Focussing into the distance will produce a clear display of the red / green point and, therefore the visual image becomes more clear.
Also the brightness setting of the reticle influences the display of the red / green point. Often the sight is set too bright for the light conditions. If you see an halo effect in the inner tube, reduce the brightness level a few steps and look again through the sight into the distance. Now, your reticle should appear clear.
Another way to check the red / green point is your viewing distance to the sight: Take a picture of the reticle by setting the focusing distance at 30 centimeters. Now, the image of the reticle should be clear and precise.
Sometimes the fuzzy perception results from a vision impairment. Check it by focusing on the fuzzy spot and turning the optics a few times clockwise or counterclockwise. If the fuzzy spot rotates, there is something wrong with the optics. If the fuzzy spot does not turn, it could be an indication of astigmatism or other vision impairment.
What distinguishes HOLOSUN® from other sight technologies?
There are several aspects that distinguish HOLOSUN® from other vendors and technologies. Very simple: the technology and the price. With the reflex sights technology, the sight does not emit an active light beam, which is why the red dot/dircle dot cannot be perceived by the target. There is no enlargement, but therefore it is parallax-free. And that makes it possible to aim with two eyes open. In addition, HOLOSUN® is characterized by the interchangeable reticle of the 500 mm line: Here you can switch between red dot or circle dot reticle or combine both. With these features we offer hunters, target shooters and special forces sights to military standards at an unbeatable price.
What are the differences between the models?
Basically, the models all work in the same way and differ only by their special features and technical data. The 500 series, for example, has a replaceable reticle, the 400 series does not. All products with a "C" in their name have a solar panel. The size of the lenses also differs depending on the model: The micros have a diameter of 20 mm, the tubes 30 mm. In addition, there are various features, such as Flip-backs, killflash or High Riser Mount. Technical data can be easily compared using our online product comparison and catalogue.
Micro versus Tube and Open: Which sight is better?
That's a matter of taste. Some prefer small, the others big. The micros are of course smaller and lighter, while the tubes and open sights provide more viewing area. Tubes also allow additional filters to be used. The choice of the perfect sight is therefore a question of optics, the field of application and personal preferences.
How far can I aim with the sights?
With a HOLOSUN® red dot sight you can aim up to 100m away.
What is the difference between red dot and Laser sighting?
The red dot sights, i. e. reflex sights, do not emit any visible light rays, so the target point is not perceptible to the target. A laser sight emits an active light, which is why the target can see the laser spot.
How does the solar-panel and auto modus work?
The solar panel is nothing more than a light sensor. In auto mode, it adjusts the brightness of the reticle, adapts it to the ambient light (ambient of the shooter, not the target) and finally supplies the sight with energy. Important: If you want to test the functionality of the battery, do not cover the solar cell under any circumstances. Otherwise, the sight "thinks" that you are in the dark and automatically reduces the red dot brightness to night mode. The red dot is then no longer visible under normal lighting conditions. To test the battery, you should try the sight in a pitch-dark room without covering the panel. When you see the reticle, the battery works fine. And if you want to adjust the brightness of your reticle yourself, simply switch to manual mode.
How long does a battery last?
The Battery life depends on the type of Sight. When operating a red dot reticle, the light duration is 50,000 hours and when operating the circle dot reticle, 20,000 hours (6 for each brightness level).
How do I shoot the sight optimally?
Everyone's a little different around here. However, the optimum distances are between 25m and 65m. You can find out exactly how to adjust the alignment of your reticle in the customer manual that comes with the sight.
Are there spare parts available?
Yes, all spare parts can be found in our price list.
For which kind of hunting are HOLOSUN® red dot sights suitable?
The sights are suitable for all types of short range shooting (e. g. push-hunting).
Are the sights suitable for night vision?
Yes, the sights can be combined with night vision devices (with 2 NV steps).
With which weapons are the HOLOSUN® red dot sights compatible?
HOLOSUN® red dot sights are supplied with Picanntiny mounts. For certain models (mainly micros) we also offer Sauer303, Weaver and Blaser mounts.
Which rails are included?
Our HOLOSUN® red dot sights are supplied with Picanntiny mounts. For the micros we also offer Sauer303, Weaver and Blaser mounts.
How do I maintain and clean my HOLOSUN® red dot sight?
This device is a precision optical instrument that deserves reasonably cautious care. The following tips are provided to ensure long lasting use of the sight. When cleaning the lenses with a microfibre cloth or soft, wet cloth, blow away the dust on surface first. Remove finger prints or other oil with lens cleaner, a soft cloth or microfibre cloth. No special maintenance is needed for the housing surface. Avoid touching the glass surface with dry cloth or tissue paper. Do not use organic solvents such as alcohol or acetone. Do not try to dismantle the device as the internal parts are specially cleaned and sealed with an anti-fog treatment. Therefore the red dot sight has a nitrogen filling you would inevitably destroy by dismantling it. Any such attempt will avoid the warranty. If repair is needed, you can call our customer service centre.
