At the core of the Challenger GS 2.7x50 is the unique combination of specially designed optics and the CF-Super Image Intensifier Tube, ensuring highest edge to edge resolution, clear, distortion free and geometrically precise image across the entire field of view.
The body of the device is hermetically sealed, enabling it to be used in the harshest of conditions, such as fog, heavy shower, dusty environment, sand storm and the like.
The Challenger GS 2.7x50 is equipped with a powerful infrared illuminator that can be used in low light conditions for observation at greater distances. The device also has an auxiliary plug, allowing the attachment of more powerful, focusable IR illuminators.
The device and the built in IR illuminator can be switched on/off with a single switch. The design of the switch prevents the IR illuminator from accidental activation, avoiding potential disclosure of the observer's position.
The Challenger GS 2.7x50 can be used in a wide variety of situations, such as night orientation, tourism, hunting, guarding of industrial facilities & private property, military, sport, patrolling and rescue operations.
