Im an experienced hunter and Ive been using this unit for three months already. Its a really very helpful device, as you can operate it easily; whats more, technical specification here is good too. It mounts easily in front of a day scope, thus your eye relief is not altered. The device is able to convert the day scope to night vision capability up to ranges of 1000 yards - shooting at night for me is now as effective, as in daytime. The price is a bit too high though, but it definitely is offset by the quality of the image that you get with this system.
