Holographic Bow Sights

If you can’t program your home VCR to tape a favorite TV show, take solace. The latest electronic bowhunting equipment is a lot easier to use than a VCR and more fun than setting in front of a TV.
A wealth of new hunting sights and sight brackets, laser rangefinders and trail timer cameras and other gadgets make bowhunting more productive and exciting.

Holographic Bow Sight Review

At first glance holographic sights appear to be similar to red dot scopes, but these sights use a completely different technology. About a year ago a company called EO Tech introduced the first holographic bow sight based on technology commonly used in-flight training simulators.

When the reticle is illuminated by laser light, an image of the reticle becomes visible at the target plane. The shooter lines up the reticle images, places them over the target, and releases the arrow.

It’s important to note that although this sight uses a laser, the light is not cast onto the target, making the sight legal for hunting in most areas. The EO Tech Holographic Sight (wikipedia link) also uses two reticles–one inside the other–to help shooters improve shooting form and reduce problems like grip torque. To function properly the outside reticle must be positioned directly in the middle of the viewing screen and the inside reticle must be aligned at the center of the larger reticle.

Lining up all these reticles may seem complicated, but in practice the process quickly becomes second nature. Shooters can choose between several different reticle options and a range finding element can also be installed in the scope.

The Holographic Sight is mounted on an adjustable bracket that enables the shooter to change the vertical point of impact. Like red dot sights, this shooting aid functions very well in low-light situations. Compared to mounting red dot scopes, however, the Holographic Sight is more difficult to install and sight in. To fine-tune the Holographic version, the shooter must be at full draw while a bow technician or helper makes the necessary adjustments.

The Holographic Sight is also considerably more expensive than red dot systems, retailing for over $4,000. Still this technology is interesting and worth taking a look at.
