The RattlerV3 25-384 pairs a 25 mm Germanium lens with an industry-leading sub-15mK thermal sensor. These technical specifications work together to provide a detection range of 1.1 miles. Large, sturdy buttons and a manual focus ring are designed to assist gloved fingers in cold winter weather, while the removable rechargeable NE-4400 battery offers one of the most robust and easiest-to-install battery systems on the market. The firmware package provides users with extensive customization options: on-board pitch scale, 10 brightness and contrast settings, warm and cold viewing modes, multiple color palettes, picture-in-picture, on-board video recording with sound, Wi-Fi hotspot, multiple zeroing profiles, shot-activated video recording, defective pixel repair, and hotspot locator. Also included is an American-made ADM mounting system.
