Made from a state of the art titanium body, the Yukon 2.5x50 Titanium Varmint Hunter NVRS is rugged, durable and lightweight. Powerful 2.5x magnification combined with the incredible light gathering capabilities of the f/1.4 objective lens puts this scope in a class that's perfect for hunters, law enforcement or military applications.
The luminous red duplex reticle is adjustable via standard internal click-stops. Reticle brightness can be adjusted or completely turned off, a useful feature for when the eyepiece has been converted to the optional camera adapter. The included remote activation switch can be situated anywhere, depending on the task at hand.
The built in IR illuminator, which features Yukon's exclusive Pulse technology, extends the low or no light viewing capabilities of the scope. The Pulse IR system provides higher levels of IR illumination without significant battery drainage.
There are many different variables that affect the distance that one can see with a night vision device, among them the object's size, the level of details being sought from the object and the conditions of observation. Night vision devices detect much further under a full moon and clear skies than they will under a new moon and cloudy skies.
Many different formulas are used to determine the statistic of maximum viewing range and the method of calculation varies by manufacturer.
The important factors to consider when evaluating any night vision device are the intensifier tube's generation, s/n ratio, level of magnification, specified resolution, along with the clarity & light transmission efficiency of the optical system.
All night vision devices sold by B&H have mechanisms in place to protect the intensifier tube from a sudden burst of bright light, but this does not mean that bright light doesn't damage the device. No matter what, bright light in any form is not good for the longevity and performance of image intensifier tubes.
