These images were taken using an adhesive foot warmer attached to a standard target. The foot warmer creates a nice small hot spot to aim at.

IR Hunter MK III – Rangefinding Thermal Weapon Sight Released
The IR Hunter MK III includes all of the features on the MK II plus:
- Stadiametric Rangefinder
- 5 Reticle Patterns
- Reticle Position ReadOuts
- Multiple Reticle Save Locations
- Battery Extender
- Flip-Up Lens Cap
- Dual Lever LaRue Mount
The IR Hunter MK III’s stadiametric rangefinder uses a system of reticle lines with adjustable angular spacing to quickly and easily dial in on a target’s distance. The MK III’s stadiametric rangefinding system allows you to select your target’s height or width then adjust a set of reticle bars to contain your target’s height or width. The MK III will then give you a corresponding distance readout. Stadiametric rangefinding is widely used in long-range military sniping and is faster than laser range-finding techniques. Electronic laser rangefinders can also give away a shooters position, but a stadiametric rangefinding system is completely covert.
IR Defense has included the much requested reticle x/y readouts which are useful to record a zero for multiple weapon systems.
The MK III is offered in a 60mm version which is 4.5X native optical magnification should be impressive.
The MK III 60mm lens option will be available in our rental pool for those of you wanting to try before you buy.

What is the difference in the Sightmark Photon XT 6.5S and Photon XT 6.5L?
Whats the difference in the Photon 6.5S and the Photon 6.5L?
The 6.5S model has an LED IR illuminator, the 6.5L has a laser IR Illuminator, and the 6.5L model is $50 more than the 6.5S. The laser IR on the 6.5L throws farther than the LED IR on the 6.5S, but the laser is much more grainy than the LED IR illuminator on the 6.5S which throws a nice smooth circular beam pattern. Both on-board IR illuminators offer less than enough beam throw and distance to allow the operator to advantage of the Photon XT 6.5(S and L) impressive range capabilities. Both on-board IRs also have a fixed beam pattern, meaning there is no option to focus the beam pattern smaller or in a different direction. If you don’t plan on using any type of external IR illuminator, it is best to choose the Photon XT 6.5L. The IR laser on this model consumes less battery power and offers better range.
There is, however, an external IR illuminator option that offers incredible throw distance, a focusable beam pattern, and better battery life – the UNV 20-IR Long Range LED IR Illuminator. If you are considering the use of an external IR, then there is no need to spend the extra $50 for the 6.5L model. Go with the 6.5S, and add a UNV 20-IR.
Helmet Mounting Options for the Horn/Bayonette Interface
There are many options for mounting your night vision or thermal device to a helmet. In the images below we take a look at the form and function of the 3 most popular horn/bayonette style interface mounts; the Norotos Legacy RHNO Mount, Norotos RHNO 2 H Mount, and the Wilcox G11
Norotos RHNO Legacy
- Known for wobble issues
- Highest profile mount
- Points your NVD display down range increasing your signtaure.
- Least expensive of the 3 mounts.
Norotos RHNO 2 H
- Smaller profile than the Legacy, but not as low profile as the G11.
- “Glide-Rite” infinitely adjustable fore/aft and 1 inch of vertical adjustment
- Less wobble than the Legacy
Wilcox G11
- Smallest profile of all 3 mounts
- Lightest of all 3 mounts
