The IR-HUNTER is not only intuitive and easy to operate, it offers superior processing power to deliver precision sighting reticles that scale as you zoom, the same as a first focal plane reticle does on a high-end riflescope. The MK3 35mm features a 2.5x optical/20x digital and a 12 degrees field of view. Includes dual levered mount, CR123 batteries, shuttered eye guard, Lenspen and hard case.
