The patented optical collimator allows for quick, one hand, full range adjustment of beam diameter and light strength with just 180 degrees of rotation. You never have to take your eyes off the target or your hand off the trigger. High power green laser light reflects intensely off the eyes of animals allowing quick detection up to 250 yards. The ND3 works well for both night hunting and game spotting. Battery life allows you to handle any emergency with over 7 hours of continuous use.

Why Green Light?
Green light is the most visible to the human eye (See Chart) and requires the least amount of eye adjustment at night. An eye that has adapted to daytime conditions generally has a maximum sensitivity around 555nm. Compared to the color red which optical spectrum is around 630 - 650nm our eye is closer to the Green region of the optical spectrum at 510 - 530nm.

Animal eyes are intensely illuminated by green laser light and clearly visible at extended distances when viewed through optics. For optimum night vision for hunting, pair the ND3 with a high quality variable power scope having a 40mm or larger objective lens providing maximum light transmission. The included ND3 mounting system for 1" tubes provides full adjustment for windage and elevation for scope alignment. Additional mounts for binocular, spotting scopes and weaver rails are included.
