The infiray outdoor ML19, the market's most compact fully multi-functional 17-micron thermal imaging monocular offers handheld or helmet-mounted versatility. With Bluetooth capability, picture-in-picture functionality and compatibility with rechargeable 16650 batteries as well as external power sources, the ML19 delivers impressive adaptability. For hands-free use, two mounting points accommodate a range of dovetail helmet mounts. The Mini's display icons adjust automatically when orientation is flipped. Operated through an intuitively labeled menu and a user-friendly rotary button, the ML19 ensures easy and swift operation, eliminating the need to search for buttons in the dark. Power supply options include compatibility with CR123A, CR123, 16340 and 16650 batteries. With a single 16650 battery, the mini runs for 3 hr and utilizing the provided power cable with a 10000 mAh USB battery extends the runtime to 18 hr. Note that using 2 x CR123A batteries with the 16650 adapter will irreversibly disable your device and isn't covered by warranty.
