The MH25W uses a 640x480 12 µm Micro III series LWIR thermal imaging core and a 25 mm objective lens to provide a detection range up to 1375 yards. The thermal images are enhanced by advanced Matrix III infrared image processing to generate crisp and clear images.

Flexible Mounting Options
The MH25W features seamless operation as a handheld monocular, or can easily transition to a helmet mount for hands-free use. There are two mounting points designed to allow for a wide variety of dovetail helmet mounts, and the display icons flip automatically when orientation is flipped.

Friendly Operation
The MH25 is operated by an intuitive, clearly labeled menu and a user friendly rotary button. This one button operation has positive clicks with each selection and allows for quick and easy operation without having to search for buttons in the dark, even when wearing gloves.

Power Supply Options
Using a single 16650 battery, the MH25W will run for 2.5+ hours and up to 18 hours using the included power cable with a 10,000 mAh USB battery. Using the included battery extender the MH25W is compatible with 16650, 16340, CR123, and CR123A* batteries.

*WARNING: Do NOT use 2 x CR123A batteries with the 16650 adapter. It will permanently disable the device.
