NVD description:
Challenger GS 1x20 is a multifunctional night vision device. The Challenger GS 1x20 can be used as a night vision monocular, NV goggles (when the device is mounted on a mask; it is possible to install the device both under the right and under the left eye), as well as a night attachment for a daytime optical sight. The body of the device is sealed, which allows you to use the Challenger GSin adverse conditions (fog, heavy rain, dusty areas, sandstorms.
The Challenger GS is based on an ingenious combination of custom-designed optics, a CF-Super image intensifier tube and a five-lens wide-angle eyepiece. In cutultate - no distortion (distortion of the image), clarity and geometric accuracy of the image over the entire field of view, high resolution. The Challenger 1x20 is equipped with a wide-angle short-range infrared illuminator, but has a slot for additional, more powerful, focusable Pulsar infrared illuminators.
On/off operations of the device and the IR illuminator are carried out using a single switch. The design of the circuit breaker provides protection against accidentsSwitching on the IR illuminator (to prevent the unmasking of the observer). The applications of the Challenger GS 1x20 are varied. These are walking or cycling night walks and night orientation, tourism, hunting, protection of industrial facilities and private property, military sports games, patrolling, search and rescue.
