The IR HUNTER™ MARK Ill takes all the features and performance of the IR HUNTER MARK II and adds a long range 60mm lens with a 7 degree field-of-view and a stadiametric range finder. The 4.5x magnification and the 640×480 resolution 12 micron LWIR thermal core deliver the perfect combination for a 24/7 weapon sighting platform.

One of the benefits of 12 micron technology is that it delivers 50% more magnification than a 17 micron thermal core when used with the same lens. This means the MARK III with a 60mm thermal lens will outperform any 17 micron scope with a 90mm lens, as they would both have the same magnification and field-of-view. Every MARK Ill system also features a 60Hz fast frame rate, which is especially useful for leading a shot of a fast moving target.

The MARK Ill brings several new features. It offers multiple reticle save locations, so you can mount the sight on different weapons and keep your reticle position. It has a new digital readout on the reticle adjustment screen that shows you exactly how many clicks you have adjusted the system. There are two new reticle patterns so you can find the best fit for your application. Finishing touches include a flip-up lens cap, dual lever LT100 LaRue mount, battery extender, and a video/download cable.
