The ND-3®® Laser Designator uses patented technology to create true night vision and turns your scoped rifle into a night hunter. Combining a powerful, green laser diode and a precision optical collimator, the ND-3® pairs with your scope and allows you to cast a bright beam of green laser light to fully illuminate targets up to 250 yards. Rotating the collimator ring to minimum creates a bright micro beam of green laser light visible up to 3 miles and rotating the same collimator to a wider setting it can be used as a light source in close quarters or following a trail in conditions with low natural light.
If you are a Law Enforcement professional spending most of your time in warmer climates, such as 40 degrees Fahrenheit or above, we recommend using the standard ND-3® Laser Designator. However, if you are more often 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™.
Research has proven that 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.
Hunting and Wildlife Observation: -Allows wildlife viewing at long distance.
Laser beam is visible up to 3 miles providing pin point rescue location
Beam diameter is easily adjusted to be a light source for night hiking. 7 hour battery life.
