ULTIMATE COLD WEATHER NIGHT VISION SOLUTION
The ND3-XL Laser Designator uses advanced green laser technology to create true night vision and turns your scoped rifle into a night hunter.
The patented Rotary Optical Collimator uses a system of 9 fully multi-coated lenses that allows full adjustment and control of beam diameter
and intensity to focus light where you need it most. Rotating the collimator ring to minimum creates a bright micro beam of green laser light
visible up to 3 miles. Rotating the collimator to more open settings provides plenty of illumination to light a trail at night or paint a target
at up to 250 yards. Battery life allows you to handle any emergency with over 10 hours of continuous use (4 hours of continuous use at 0˚F).
Excellent source of illumination for Hunting, Fishing and Shooting Sports
If you are an outdoor enthusiast who spends most of your time in warmer climates, such as 40 degrees Fahrenheit or above, we recommend using the
standard ND-3® or ND-5® series of products. However, if you are mostly spending your time in rough and cold weather conditions in temperatures 40˚ F
and below and looking for a compact, light weight and reliable source of light, then look for the ND-3 Subzero™ line of products.
Why Green Lasers?
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
