Edge Detect Mode
The IR Hunter MK III has an Edge Detection feature that produces an entirely different new way of viewing your target. Edge Detect mode is also a fraction of the brightness of other modes so your eyes are not as prone to night blindness after coming off the scope. There are certain tactical situations that require your display to me very dim so as not to be detected, and to reduce night blindness after coming off of your eye piece. The IR Hunter MK III has an advanced feature that has been used on certain high end military thermal sights for years. Edge Detect gives you an entirely different way to view your target, with 90% of the screen black, and only the edges surrounding your target white. This is an extremely useful feature and is not found on any other commercially available thermal weapon sights.
Reticle Position ReadOuts
Not only can you save 4 weapon sight reticle locations and 4 clip-on scene locations, but each one of those locations will give you a simple X and Y value for as many locations as you need. This means that you can set up a MK III on as many weapon systems as you want and always maintain a return to zero.
MAXPOL Polarity - White Hot/Black Hot
Most thermal weapon sights come with only one level of white hot and black hot. Some come with color pallets, but the majority of users find themselves using black hot and white hot exclusively. Rather than giving you color pallets that you will most likely never use, IR Defense designed the IR Hunter with 3 levels of white hot, and 3 levels of black hot. This allows you to choose the perfect level of polarity in the white hot or black hot modes for any situation.
The IR Hunter features an extremely benefitial technology called Enhanced Target Recognition, or ETR. Most thermal systems auto adjust the image contrast and brightness across the entire display screen. This can lead to washed out image around the crosshair or for a majority of the display area. ETR selects the are on the display to adjust leaving you with a perfectly adjusted image.
DFC - Digital Focus Control
Digital focus control allows you to not only focus your picture to the optimum setting, but it also allows sharpening of the entire picture. This technology will make a 320x240 appear more like a 640x480. For a detailed look at what DFC can do to image quality look at the image below. This image is raw, unedited, and is not a simulation

Protective Lens Window
The germanium lens can be the most costly component on a thermal device and it is always the most costly component that is exposed to damage from the elements. IR Defense designed a highly transmissive IR window that protects your germanium lens and can be replaced. Replacing the protective window will only cost a fraction of replacing the entire germanium lens.

Level 1 controls the 6 polarity settings, edge detect and digital zoom.
Level 2 controls contrast and digital focus control(DFC).
Level 3 controls calibration and brightness.
Level 4 controls reticle selection, clip-on mode and adjusts the rangefinder.
Level 5 controls windage and elevation adjustments,
Level 6 controls image capture and Enhanced Target Recognition(ETR)
Level 7 allows you to review captured images.
Level 8 controls the reticle lock, framerate(30hz or 60hz), video output, symbol sleep mode, startup settings, battery settings,display auto dimmer, deleting captured images, reticle location(A.B,C,D) and horizontal and vertical rangefinder units.
Video Output
The IR Hunter features a high end mil-spec Fischer connector. This connector costs much more than connectors on competing scopes, but IR Defense decided to choose a video connection option that will last under harsh environments and years of abuse. Video cables and connector quality is very important both in tactical and hunting/recreational situation. One flaw in a cable can leave you wishing you had your kill shot on video. We have a high quality custom video cable for the IR Hunter MK III that connects the MK III directly to a mini DVR. These cables are rugged and built to last.

Since the launch of the IR Hunter we here at UNV have seen IR Defense deliver every scope with a high level of quality control and customer service. We not only sell the IR Hunter MK III, we use the IR Hunter MK III on a frequent basis educating customers and night hunting.
The IR HUNTER has been designed and built by a team that has been delivering great thermal sights, industry-wide, for 20 years. Not just technicians, the IR HUNTER designers are enthusiastic, American Shooters as well. We passionately demand reliability and precision from our optics when putting rounds down range no matter the weather conditions, nor the time of day. This drive and commitment lead us to make the best possible thermal scope,and, we did it! It was achieved,100% here in the USA, and without compromising quality or reliability. That would typically be enough; but the team went a step further, introducing the IR HUNTER thermal weapon sight to market for a highly competitive price. IR HUNTER contains all the features and ergonomics you have wanted, combined into a sleek system made to securely fit onto your rifle. You should find comfort operating the IR Hunter's Turret Knob controls as they are located where you expect them to be, same as your day optics.

Mk3 35mm
Absolutely worth the money! I bought the trijicon mk3 35mm thermal scope after quite a bit of research and it is every bit as good as the online videos. With the extras (DVR and extended battery) makes it worth the price. The service at UNV is second to none. The guys were very patient and knowledgeable with my many questions and concerns. Being a disabled Veteran and father of 6 I couldn’t afford to pay for something I that wouldn’t meet my expectations and I’m not disappointed!
Originally had looked at getting the pulsar trail xp50 which my buddy decided to purchase , it’s good but my buddy is jealous of my mk3. -
Blown away...
I admit my experience with thermal imaging is limited to my only looking through a friends two year old ATN scope a couple of times and for a couple of minutes each time and don't know any of it's specs, just the brand. I did a ton of research though before going a different route with the IR Hunter MKIII. And I am simply blown away by it! My friend and I compared them sided by side this weekend and he is blown away by it too. The image is super crisp and clean and smooth no matter how fast I turn from side to side. The MKIII even picked up the heat rising from one of those little fire chimney things on a guys back porch from almost two blocks away. The ATN didn't see it. I haven't shot it yet but imagine it will perform as expected. I couldn't be happier!!

You'd Be crazy to spend your $ on anything else!
After reviewing and reading everything about this weapon sight for a month, I purchased one. Received the sight in one day, mounted it up and spent just 10 mins sighting it in. Then I got familiar with the operating of the sight. It's so simple to become adjusted to the menu's. Took it out and harvested 5 pigs unsuppressed. I wanted to see how it would be to have to look for them when they knew they were being hunted. It's was flawless.
Thank You to Tyler for taking the time to discuss all my options, Ultimate Nightvision is a first class operation. Now I have to finish out my wait for the White Phosphorus googles to get here. -
Perfect Cable!
This cable is very well made. When it hooks into your thermal you can bet your ass it's not coming out under the harshest of conditions. I just plug it in and know that it's going to give me that perfect video everytime! Awesome job, ultimatenightvision!
