BAC - Bindon Aiming Concept
After many years of searching for and developing improved small arms weapons sights, Glyn Bindon made an amazing discovery. The legendary aiming speed of the Armson O.E.G. can be combined with the accuracy and precision of magnified scopes. What was discovered is that the human brain automatically switches to the best system when you look through the scope with both eyes open. Two major universities have confirmed that anyone with normal vision (over 95% of the population) can learn to use the brain powered zoom in seconds.

 

How the Bindon Aiming Concept Works
Both eyes must be open. Scan from left to right, while continuously scanning the brain will choose the non magnified version (your left eye), as soon as you near your target and stop on it your brain chooses to use the magnified version (your right eye). This gives you an unlimited field of view and makes it very easy to hit multiple targets or moving targets in any lighting conditions. It may sound confusing until you actually look through one, it is very simple and extremely effective.

 

The Nature of Binocular Sighting


Human vision is based upon a binocular (two eyes) presentation of visual evidence to the brain. The word binocular literally means using both eyes at the same time. We most often associate this word with binocular instruments such as field glasses or a binocular microscope. These instruments specifically strive to present the object to be viewed the same way to both eyes.

Vision research material was examined for its assistance to understand the optically aided weapon aiming process. Three major types of optical enhancement were compared. There are strong customer preferences in reticle designs, some simple reticles enhance the speed of target acquisition, others allow for greater precision in a given time limit.


The simple substitution of a bright red dot for the usual cross-hairs makes it very easy to keep both eyes open. Just as in the Single point or Armson O.E.G. sighting, the brain merges the two images. During dynamic movement, the scene through the telescope blurs because the image moves more rapidly due to magnification. The one eye sees the bright dot against the blurred target scene, so the brain picks the scene from the unaided eye. The shooter swings the weapon toward the target while perceiving the dot indicating where the weapon is pointed. As soon as the weapon begins to become steady in the target area, the brain switches to the magnified view.

A long search was made to try to combine the speed and non-battery features of the Singlepoint or Armson with the precision of the telescopic system. This discovery was made several years ago. Trijicon has sponsored research in the field of human vision to better understand this generic phenomenon. Although the study concentrated on the Armson O.E.G., some aspects are applicable also to the Bindon Aiming Concept.
