The ATN Obsidian 4T 640 2.5-25x Thermal Imager Smart HD Monocular is a compact thermal imaging device that can detect a decent distance to targets with the heat signature of prey, which can make identifying certain animals a bit easier. With the ATN Obsidian 4T 640 2.5-25x Thermal Imager WiFi Dual Core Processor , the observer can view images or video from the thermal imaging device on a smartphone or tablet, similar to how a binocular does, and the advanced image sensor can even penetrate snow, dust and haze to provide the viewer with a clear image. The image and processing power of the ATN Obsidian 4T 640 2.5-25x Thermal Smart HD Monocular w/ 4th Gen Sensors is astonishingly powerful, and since one of the core functions of the device is running the video stream, the OTS 4T 640 2.5-25x Thermal Imager w/ 4th Gen Sensors also saves power, resulting in extremely long periods of inactivity before needing a new battery. The ATN OTS 4T 640 2.5-25x Thermal Imager runs on an ATN Obsidian IV Dual Core Processor , ensuring swift calculations and a smooth zoom with intuitive controls that make it easy to use. The ATN OTS 4T 640 2.5-25x Thermal Imager works with a wide array of sensors including a 3D accelerometer, gyroscope, barometric pressure sensor, and thermometer. In short, the ATN OTS 4T 640 2.5-25x Thermal Imager Smart HD Monocular can do it all!image
