These devices are fitted with a five-lens eyepiece that minimises distortion at the edges of the field of view and increases sharpness and contrast of the image. The compact glass reinforced plastic housing ensures high durability and reliability and the Challenger range has an IP46 level of dust and water protection allowing it to be used in any level of precipitation.
The Challenger is operated by a single switch, which activates the device and the integrated IR illuminator sequentially. This prevents the IR illuminator from activating accidentally.
This product is equipped with two diametrically positioned tripod sockets, which allow for an attachment to an optional head mount for observation with the left or right eye or on a tripod. These sockets also enable a higher powered IR illuminator to be fitted.
There are four models in the Challenger GS range that span four different specifications; the lowest magnification being 1x20, the 2.7x50, the 3.5x50 and the highest magnification 4.5x60.
