Holographic weapon sights by L3 Communication EOTech are some of the most unique weapon sights on the market today. In EOTech's HW sights the reticle is replaced by a hologram, that is projected by a laser. What makes these sights extremely effective for close combat and fast response situations is the fact that EoTech's reticle is large and yet it does not obstruct the field of view, while remaining highly visible in any light, centered in the scope regardless of the view angle. It does not distract the operator. The dot is visible to the user only and can not be spotted from any other angle even with the use of night vision devices. Flat window surface has a special anti-reflective coating reducing the likelihood of detection.
Holographic weapon sight (collimator sight) is classified as an open scope or reflex scope type, becasue the shooter does not have to close one eye during operation. The larger field of view allows operator to use his periferal vision and reduce response time to possible threats or changes in the tactical or hunitng situations. It should be noted, that holographic weapon sights allow for significantly higher rate of fire, compared to traditional riflescopes, which makes it a great choice of sight when engaging moving targets.
Some EoTech models have special "NV" mode designed for compatability with night vision devices. When switched to night vision mode, the brightness of the reticle is significantly improves visibility through night vision devices while reducing halo effect around reticle.
Eotech Holographic weapon sights have another unique characteristic - they can be used in any weather conditions - rain, sleet, snow and even during heavy fog. Reticle is visible in the sight even when the holographic window is covered with dust, snow and even partially broken.
L3 Communications EOTech produces several models of holographic weapon sights (HWS):
* EOTech 510 - the most basic, but probably the most popular models, without "NV" mode
* EOTech 550 - these models are similar to 510's but have "NV" mode built in order function in conjunction with night vision devices (I-IV generation)
*EoTech XPS2 and XPS3 - the latest and the most compact holographic sights on the market. They are powered by a single type 123 battery. Models XPS3 have "NV" mode capability built in, while XPS2 do not.
*EoTech G23.FTS 3x Magnifier - is a stand alone optical magnifier that is designed to be placed in front of the holographic sight and provides for 3x image magnification. Magnifier is equipped with a Flip-to-side (FTS) mount that allows for the magnifier to be quickly "flipped to side" when the magnifying capability is no longer needed without having to remove the magnifier from the mounting rail. G23.FTS magnifier is compatible with all EoTech HWSights. However, the models that have controls positioned on the rear of the sight (away from the operator) make these models difficult to operate with the magnifier.
The main distinguishing characteristics between EoTech models 510 and 550 are the battery type (AA, NN or CR123) and corresponding size differences, and also
reticle type. Standard reticle type is a 1 MOA dot with a round circle 65MOA (A65/1). Alternative reticle is simply a 1 MOA dot (wthout a circle) - (D1).
Eotech Sights XPS2 and XPS3 use one CR123 type battery, have the same size and have 3 different reticle types:
-A65/1 - 1MOA dot with a 65MOA circle (designated as -0, as in XPS2-0)
-D1 - 1MOA dot wihout a circle (designated as -1, as in XPS3-1)
-2 1MOA dots with 65MOA circle (designated as-2, as in XPS3-2)
