Thermal Imaging

Featuring an uncooled FLIR Tau 2 thermal detector that captures clear images, this Zeus sight has the necessary technology for close- and mid-range tactical operations, real-time surveillance and intelligence gathering. It also provides plenty of great functions for hunting. It can cut through snow, dust, fog and other problems with visibility by using heat signatures to create images instead of relying solely on available light. This makes it an ideal tool for both day and night use.

There are 13 color palette options for you to choose from, including black and white. The color palettes show images according to how you want to see them, such as red for extremely hot targets. The “white hot” and “black hot” options show hot items only in black or white. There are six reticle patterns to pick from, as well, and the reticle’s aiming point can be adjusted in 1.3 MOA increments.

Other Features

Encased in a shock-proof, ergonomic aluminum housing filled with nitrogen to make it waterproof and fog-proof, the Zeus 3 was made to withstand the most hostile environments and can be submerged up to 10 meters of water for 30 minutes. Compact and lightweight, the Zeus 3 has a Picatinny mount for easy attachment onto your rifle, with weaver rails for support.

The lens is adjusted manually, and the controls are located on the top of the scope, making adjustments while shooting fairly simple.
