CF-Super image intensifier tube
At the core of the GS line is a unique combination of specially designed optics and the CF-Super Image Intensifier Tube, which provides the highest edge-to-edge resolution performance ever seen in a budget consumer NV product.

Built-in IR-illuminator
Powerful IR-illuminator is useful for observation at insufficient levels of natural illumination on above-average distances.

All operations are carried out with the help of a single switch that sequentially turns on the unit and IR Illuminator.

The Challenger GS are outfitted with a new five-lens eyepiece that minimizes distortion across the edges of the field of view and increases image sharpness and contrast. When rotating the eyepiece, it remains fixed.

The body of fiberglass reinforced plastic is able to effectively withstand impact, moisture and dust which allows the units to be used in extreme conditions.

Two diametrically positioned mounting rails with a ¼” tripod mount are used to attach to the Head Mount. Additional Weaver rail on the body is designed to install extra Pulsar IR Illuminator or other accessories.
