Yukon Advanced Optics 24095 User Manual

OVERVIEW

The Challenger Night Vision Device is a new tube Gen.1 based unit that has a state-of-the-art design
and a wide angular field of view. The device is outfitted with a new five-lens eyepiece that minimizes
distortion on the edges of the field of view and increases sharpness and contrast of the image. The soft
rubber eyecup conceals the light emission from the tube thus permitting a user to stay unnoticed. The
housing of metal and plastic ensures extra durability and reliability during usage. The Challenger has an
IP46 degree of protection (IEC 60529), i.e. this device is protected against water and dust which
increases the range of its usage.
The device is equipped with an IR illuminator necessary for normal observation in moonless cloudy
conditions in total darkness.
The Challenger is equipped with two 1/4'' sockets which allow it to be fixed on the head mount
(included) and used as goggles. Additional accessories such as IR flashlight, directional microphone can
also be mounted on the device. The device is fully self-contained and can work up to 72 hours on a
single CR123A at temperatures varying from -20 ºC to + 40 ºC.

Your Challenger is ideal for professional and amateur use, including:

• Night observation in natural environment
