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 comes down to personal preference and specific use but there are a few places where it's hard to beat an EOTech style red dot sight.

Red dot sights typically have no magnifications such as a more traditional cross hair rifle scope and are therefore usually better suited for short to medium range applications.  Many sports shooters and hunters prefer HWS sights like EOTech over standard iron sights or sight beads on many firearms including handguns, shotguns, rifles and even bows.

Target acquisition times in close up situations, especially on moving targets, can be much faster with a red dot style sight.  In fact, this is probably the single greatest advantage of these EOTechs and similar sights.  It's the reason many hunters, particularly those taking flying game, have started using EOTechs.

The ability for the shooter to keep both eyes open while aiming complements and adds to the fast target acquisition characteristics of the sight. A hunter finding himself suddenly upon his game or an individual engaged in law enforcement or military duties will both find that an EOTech gives them an immense advantage.

Another reason the red dots are a bit faster than traditional scopes is due to the fact that there is no set eye relief.  At an inch or three fee the dot and the sight picture remain equally clear.  In a tight situation this is great since you don't have to worry about getting your eye to that "just right" spot behind the sight to be able to see your target and your dot/cross hairs at the same time.

Perhaps one of the most impressive things about the EOTechs is the ability to keep aiming and shooting accurately even when the sight is partially obscured or even busted.

I borrowed these images from the EOTech website because they show quite dramatically how well this sight can perform even in extreme situations.  Though most of us won't need to worry about trying to shoot if our sight is covered in mud, it's nice to know we can.
