A true red dot sight such as an EOTech is acutally a holographic projection. This class of optics are known technically as Holographic Weapons Sights, usually shortened to “HWS”. Just because it’s interesting I’ll try and give a brief summary of how holographs came about and how we can now buy one to put on top of a gun.
Simply defined, holography is an optical process of wavefront reconstruction of a three dimensional object by recording the interfering pattern of light. The concept and theory of holograms was …

I just thought I’d make a post about some interesting characteristics of EOTech sights that really do make them great weapon optics. One of the things that the company prides itself in is the abundance of features and processes in manufacturing that makes the EOTech sight extremely rugged and durable. Let’s briefly look at a few of these:
 
-The optical cavity where the hologram is produced is thoroughly sealed allowing for the possibility of submersion and ensuring fogproof operation.
 
-All of the EOTech’s electronics are completely encased in a special …

This article will mainly deal with why and average sportsman/hunter would be interested in an EOTech sight.  Someone using their weapon in a tactical manner, I’m sure, would already be fully aware of the many advantages this style optic offers its user.
With all of the choices in firearms optics out there, red dot sights being only one of many, you may be wondering if a holographic weapon sight (HWS) is the right choice for your firearm and for the applications you intend for it.  Well, as with most things it …
