At the core of the Challenger GS 4.5x60 is the unique combination of specially designed optics and the CF-Super Image Intensifier Tube, ensuring high level edge to edge resolution with clear, distortion free and geometrically precise images across the entire field of view.
The body of the device is hermetically sealed enabling use in the harshest conditions, including inclement weather, fog, heavy showers, dusty environment and similar.
The Challenger GS 4.5x60 is equipped with a powerful infrared illuminator that can be used in low light conditions for observation at longer distances. The device also has an auxiliary plug, allowing the attachment of more powerful, focusable external IR Illuminators.
The device and the built in IR illuminator can be switched on/off with a single switch.
