The OTS-HD 640 1.5-15x19 Thermal Digital Monocular from ATN features gyroscopic image stabilization that keeps the image steady at a higher power. The OTS-HD can capture 1280 x 960 still images or video at 30 fps and saves them to an on-board microSD card slot. A micro-HDMI output lets you display the captured photos or video to a computer or TV for playback and storage. An easier way to share images is to use the built-in Wi-Fi. It features a Smart Rangefinder, with only two clicks and a simple shift of the scope you will be able to range your target. Once ranged in your reticle will automatically adjust its point of impact.

Connect the monocular to any device running the free Obsidian app and stream the current view, save images to the device, and instantly post them on social media, message them, or email them to friends and family. A built-in GPS antenna enables geotagging your photos or video so you can map where every image was taken. The GPS system will also log your altitude and speed so you'll know if you'll make your next waypoint on-time or if you need to pick up your pace.
