You may not be able to see them with the naked eye but the ATN OTS LT 320 3-6x Digital Thermal Monocular will show you targets in the dark. Built around ATN's 320 x 240 12-micron 60 Hz Obsidian LT Core sensor the OTS LT delivers a detection/recognition/identification (DRI) range of 910/455/290 yards. Imagery can be viewed in black-hot or white-hot mode on the 1280 x 960 HD micro-display. One charge with the USB Type-C cable will power the monocular for more than nine hours. Weather-resistant construction ensures the optic will be ready for action in even inclement conditions.
