Blind Shooters
From Shooting Wiki
Equipment
The Austrian Company called Swarovski Optik have developed a sight which enables blind shooters to achieve a level of accuracy very close to that of sighted shooters. The sight is designed for use on an air rifle and looks like a conventional telescope sight. mounting etc are the same. The sight is designed to collect and measure the level of light reflected from the target using a photo-electric cell which is then converted into sound. The center of the target is brilliant white and then moving outwards from the center increasingly darker levels of grey are encountered until off the target is matt black. The closer to the centre of the target you are aiming the greater the level of light reflected and hence the higher the frequency of sound which is heard by the shooter via a pair of headphones. The sights are adjustable in the normal way to alter the mean point of impact.
