The AGM Rattler LRF is a compact thermal imaging scope developed for 24-hour operation under any weather and environmental conditions. Equipped with a highly sensitive, 12m thermal detector and 1024×768 OLED monitor, the AGM Rattler LRF provides a clear image under harsh environment conditions. The device can be used as a thermal riflescope or handheld monocular and can be applied to scenarios such as patrolling, hunting, static observation and more. The built-in laser range finder of the AGM Rattler LRF is designed to determine the exact distance between the observer and the target. Measurement results are displayed on the scopes monitor. One 18650 rechargeable battery gives the device up to 4.5 hours of continuous operation time. An external 5V power bank (battery pack) can be easily connected via a USB to USB-C connector for a significant increase of operating time. The device is equipped with fast EMMC storage for on-board video recording and image capturing. An internal Wi-Fi module for live video streaming and video/image recording via application are also included.
