The Challenger GS 1x20 is a multifunctional night vision device.
It can be used as a night vision monocular, night vision goggles (if set up on a Head Mount; the device can be used either for the right or the left eye), or a night attachment for a day optical riflescope or a collimator sight.
The body of the device is hermetically sealed which enables use in inclement weather (fog, heavy shower, dusty environment, sand storm etc.).
At the core of the Challenger GS 1x20 is the unique combination of specially designed optics and the CF-Super Image Intensifier Tube, enabling the highest edge to edge resolution, clear, distortion free and geometrically precise image across the entire field of view.
The Challenger GS 1x20 is equipped with a wide angled, short range, infrared illuminator. As well, more powerful, focusable IR illuminators can be attached via the auxiliary plug.
The device and the built in IR illuminator are switched on/off with a single switch.
The design of the switch prevents the IR illuminator from accidental activation avoiding disclosure of the observer.
The Challenger GS 1x20 is useful in a variety of situations, such as nocturnal excursions on foot or by bicycle, night orientation, tourism, hunting, guarding of industrial facilities and private property, military, sports, patrolling and rescue operations.
