Whether you’re seeking a handheld thermal monocular or something helmet-mounted, the iRay Thermal MH25 offers an excellent option. In fact, one reviewer praised the MH25 Mini as an “outstanding thermal monocular. The clarity and usability of this unit are unreal.” 

The MH25 is one of the best-in-class night vision thermal scopes in stock anywhere. This brief guide will fill you in on the product description, details, and uses of the unparalleled iRay MH25. 

iRay Thermal: Features and Benefits

The MH25 is the most compact, multi-functional 12-micron thermal imaging monocular money can buy. It easily fits in your pocket and can be used as a handheld or helmet-mounted device, depending on your needs. The MH25’s lightweight design also makes it comfortable and easy to use for extended periods. 

The device’s 640 x 480 core ensures that the heat signature image quality is crystal clear as you move through the dark. Every image and video is electronically optimized, even when you’re using the picture-in-picture feature. 

Another reviewer compared the iRay Thermal MH25 to other thermal optics devices and noted, “this thermal still has the better image.”

Changing settings and navigating through menus is simple with one-button functionality, even when it’s pitch black. There are four color settings you can choose from when using the iRay MH25 for night vision: red hot, white hot, black hot, and rainbow. The 1280 x 960 screen resolution allows you to identify everything you see with incredible accuracy. 

The batteries used in the MH25 are easy to swap out, even in the dark. The two batteries available with the iRay MH25 Mini are rechargeable (using the USB C cable included with the device). 


Here’s a list of everything included with your new iRay MH25:

  • Two rechargeable batteries 
  • Carry case with strap
  • USB Mini Cord to charge batteries
  • USB C cord with a 90-degree elbow to run the external power pack
  • USB C/USB/Analog cord for video 
  • User manual

The height of the MH25 is 4.8 inches, the width is 2.8 inches, and the length is 5.03 inches. The weight is just 8.64 ounces, just a hair over a half pound.

The optical magnification of the MH25 is 1.1X, but the digital magnification goes up to 8X. The sensor’s pixel size is 12 microns, and its frame rate is 50 HZ. The objective focal length and diameter are both 25 mm.  You can get clear pictures and images from any distance and save them to open in your browser once in range of a wifi signal.

The MH25’s detection range is 1,375 yards, just a bit shy of a half mile. The device uses a stadiametric rangefinder, allowing you to determine the range to your target while minimizing human error.  

The battery offers about 90 minutes of continuous use. And if you turn your iRay MH25 on and off, you’ll get more out of your MH25 batteries. However, the batteries are rechargeable and can be charged with a power pack that is less than 5 volts. If you want to carry extra batteries with you when you’re hunting, be sure you purchase extra ML1665R rechargeable batteries. 

The price of the MH25 is $3,999.98, a very competitive price compared to similar night vision products on the market.

Use Cases

The most obvious use case for the MH25 is hunting, using it as a scanner. You can easily avoid spooking your target by scanning ahead with your thermal monocular. For example, you can:

  • Hunt deer. When you enter the woods during deer season, the last thing you want to do is spook your quarry. Using your MH25 either handheld or on your helmet can help you see when deer are nearby so you can stay still and silent until they leave the area.
  • Stay safe in the field. When you use a thermal monocular, you’re not using the scope on your gun to try to track your prey. That means you’re also not pointing your gun at any other hunters who might be out there. Plus, you’re not causing yourself unnecessary back pain by having to hunch over to look through your scope.

Another popular use for a thermal monocular is for challenging home repair tasks. Contractors can scan walls with the MH25 to see where hot and cold spots are and take pictures to identify and present the exact trouble spot. The MH25 allows those working at night to confidently address the problem without doing a lot of unnecessary work. 

The MH25 Adapter

If you’re looking to mount your MH25 on a helmet, you need the correct adapter. The iRay USA Dovetail Adapter for Mini-Series is exactly what you need. This adapter allows for a wider range of eye relief than other dovetail systems.

The iRay Thermal MH25 is a great pick to add to your night vision ensemble. You can stop scanning for your target with your scope, saving your back while keeping other hunters safe. You can easily find hot and cold spots in a house and achieve higher repair efficiency. Click here to learn more about the MH25 today.
