Stadiametric Rangefinder

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.

Image Capture
The MK III has an image capture function that allows a user to capture a full-frame image from the 12 micron BAE core. When downloaded these images do not include the icons seen through the eye piece of a MK III, but they do give a great representation of the true image quality seen through the eye piece.

Reticle Position ReadOuts

Each X/Y location 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.

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.

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.


ETR - Enhanced Target Recognition
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.

Edge Detect - Tactical Mode
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.

IR Hunter Menu Operation
The IR Hunter MK III has 3 turret controls that operate the menu levels and functions. The turret controls operate the menu icons corresponding to their location(top turret operates the top menu icons etc).
The menu levels are numbered from 1-8 and each level has different functions.
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 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.

IR Hunter Right Angle Cable

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.

    Excellent service and products at UNV

    Posted by John W on May 20th 2020

    I continue to be impressed by Todd Mack and the excellent service and products at Ultimate Night Vision. Ordered the Trijicon Mk 3 Hunter 60mm, and package, and it is unbelievable... so incredible how heat from birds, animals, and humans is picked up and seen. Today looking into the woods, I saw 3 squirrels very clearly at 100 yards away ONLY with my thermal scope, and when I put it down, I could literally see only dark trees and soil with my unaided eyes in the afternoon on a cloudy day. You can pick out individual squirrel legs at 100 yards when they move, and the image is not blurred or slow at all, the 60 Hz lens system is amazing. Top notch scope and company. Thank you UNV.

    Exceeded expectations on visual quality

    Posted by Dave on Mar 30th 2020

    Receiving was a pain due to FedEx.

    On my rifle, I get 3/4&quot; groups at 65 yds (range at the camp), the thermal was getting ~2&quot; groups. I wrote that off as &quot;it&#039;s a rental that has been put on many rifles&quot;

    The detection and visual quality exceeded my expectations. The quality of videos available online suck compared to in person. I saw a heat source and confirmed it was a rabbit at 120yds in total darkness within 5 -10 seconds. 20x zoom was useless as it was pixelated.

    I saw a guy at 150yds drinking from a cold can put of a paper bag. I could detect buildings well over a mile with detail. I detected cars (no people were out) at 500 yd.

    I was initially upset because I couldn&#039;t find any hogs. This was a learning for me that thermal won&#039;t solve your problems if the pigs aint there!

    I recommend a rental. The process is very simple. It took a 2 minute call, then I got an email from UNV with rental terms. I was finished with it under 30 minutes.

    Like seeing in the day in black and white...

    Posted by TJN on Feb 11th 2020

    What can I say, I did a lot of research before I pulled the trigger on the Trijicon IR Hunter MKIII 60mm. Buy once cry once has been my motto for many years. UNV and Todd made the decision easy as to where to make this HUGE purchase. Not only do you get extra goodies with the purchase, but the SUPPORT is worth so much more. I could NOT recommend UNV enough. I have told all my friends about UNV and I will do business with them again, well as soon as my piggy bank fills back up. The unit is AMAZING and I have only messed around with it in my yard for now. I will get it mounted on a LWRC REPR 308, 16&quot; with an older Thunder Beast 30BA Can. Shalom!!!

    IR Hunter MK III 60mm

    Posted by Unknown on Aug 27th 2019

    Hi Tyler! Scope controls are very intuitive and easy to use. At times picture quality is astounding. So far, humidity has been very high for the most part, degrading resolution. Got lots of pictures, day and night. Just got the SD card for the MDVR. When I get that hooked up and going, I&#039;ll be mounting it on a .308. Sure looking forward to that! I&#039;ll be sure to call if I have any questions. Last night it was pitch dark overcast. Saw 3 does in the field across the way and a bunny in our front yard. Will keep you posted! Thanks! Jim

    Ultimate Night Vision

    Posted by Curtis on Feb 5th 2019

    Ultimate Night Vision is a grate company to perches from. I called several companies when looking for this product and they had the best deal and by far the best public relations it was like talking with a good friend I have recommended them to everyone that I know is interested in purchasing a thermal scope. As for the scope it has preformed great I have had it out in below zero temps for hours at a time and the rechargeable battery pack has been great. When my hunting partner is changing out batteries on each stand or two due to the extreme cold temps
    (different brand scope) mine has no problems at all holding a strong battier. The added products for the same price as the scope from other companies was a huge selling point.

    IR Hunter MK III

    Posted by Ross B on Sep 28th 2018

    I originally was buying this scope to use as a handheld, to use with my ATN Thor 640 that I had on my rifle. Tyler told me to be prepared to mount this scope and use the Thor for a handheld. As usual he was right. After looking through the MK III, I can hardly use the Thor at all.

    The MK III will easily show me a coyote at 800 yards that the Thor has no idea is there. The Thor is not a bad scope, I shot more than 30 coyotes with it last season. It&#039;s just that the MK III is so much better. The sight picture will floor you the first time you look through the scope. On a clear night with good thermal balance, the comparison between the Thor and the MKIII is like comparing the binoculars that came with your son&#039;s toy cowboy outfit to a pair of Leupold 10x50s.

    The clarity is amazing. The little bit I have tried it, due to this scope&#039;s clarity and sight picture sharpness, it can be used as a daytime scope for shots at a couple of hundred yards. Not a complaint, but the field of view is very tight at 7 degrees. Anything close takes a bit to find, but again not a complaint. I have trouble keeping my hands warm and the 3 turret adjustment system is a God send. Adjustments are easily made with the heaviest winter gloves on. I found this especially helpful as this scope needs almost constant recalibration. At least in very cold Iowa weather it does. Inconvenient, but certainly not a deal breaker. Some bad points that I have found. The rerticle you use, unless you use the R1 choice, has to be set every time you turn the scope on. The reticle is either black or white and you have no control of which the scope uses. It determines, by sensing the light conditions, which color to be. I like to think that I am smart enough to choose the color that will work best in my situation. The range finder works great on a static target, but try to do the adjusting necessary on a coyote that never stands still for more than a few seconds. I have never hunted hogs, but if they stand still for more than a few seconds, then this range finder is the thing to have. When using the set-up screen and setting your vertical height, unless you always want it set to 2 yards, you have to go in and adjust it every time you turn the scope on. The &quot;manual&quot; that comes with it is lacking some needed info. It doesn&#039;t mention the settings that have to be made each time the scope is turned on: video out must be turned on (if you intend on taking video) and frame rate has to set at 60hz. As mentioned, the yardage for the range finder goes to default when the unit is shut off, both vertical and horizontal. It lists ETR as one of the features but doesn&#039;t tell you what it is. I know now, I looked it up. Minor things but I had to call Tyler and ask why my DVR no longer took videos and told me that there was no input. Somehow my frame rate had gotten changed to 30hz and that doesn&#039;t work. If you can afford this unit, then you can afford the external battery kit for it. It will pay for itself many times over both in dollars and convenience. The small lithium batteries this scope requires can be purchased in the $25 dollar range for a dozen.

    They will last at most about 2 hours. I use the external battery and never turn the scope off when I am out. That avoids making all the changes in the setup screen and the battery is good for better than 16 hours and is rechargeable. The on-screen battery indicator doesn&#039;t work with the external battery but the battery itself has an indicator on it. All-in-all you couldn&#039;t get this scope away from me for any amount.
    I&#039;ve gone out with this scope when I could barely see the road because of the heavy fog. You have to look down the gun barrel every so often to make sure you are pointing it in the right direction, but finding targets is not a problem. It won&#039;t &quot;see&quot; as far but I didn&#039;t have any problem shooting a fox at 200 yards in heavy.

    I was able to detect a ground squirrel at 400 yards and shoot a ground squirrel at 257 yards on clear day.
    The minor complaints stem mostly from the reliance of the easy technology of the day. A bad button on the TV remote sends us into a rage. I can remember when we had to get up and cross the room to change a channel. And then adjust the vertical hold. In closing, if you are looking for a thermal weapon sight, look no further than this unit. I guarantee that you will love it.

    Ir hunter mkiii

    Posted by Unknown on Feb 19th 2018

    What a kick ass experience! I had a event I needed this scope for in NC and they were able to work with me to get it early. Very fast shipping. Everything was organized in the carrying case. Plenty of batteries which lasted a very long time. The instructions were easy to understand. I was impressed. Spend the extra money and get the mkiii you won&#039;t believe how far you can see. Just make sure you do the research on the mount you&#039;ll need for your weapon too, Awesome experience and will be renting again.

    Great product

    Posted by KD on Feb 6th 2018

    Awesome product to use,I rented the scope for a weekend coyote competition and definitely wasn&#039;t disappointed! Could see coyotes coming from well over 800 yards. Toughest thing to get used to is limited depth perception when they get closer and hard to judge the yardage before the shot, Especially when hunting new ground. But like anything else you get better with it with experience. Definitely will be renting again.
