Description And features

The Varmint LRF is a compact thermal imaging scope with built-in precision laser rangefinder. Equipped
with a highly sensitive, 12μm thermal detector and 1024×768 OLED monitor, the AGM Varmint LRF
provides a clear image under harsh environmental conditions including darkness, fog, smoke, dust, rain,
snow, brush, camouflage, etc. The Varmint LRF’s user-friendly interface, comfortable and ergonomic
operating controls makes its use incredibly easy.
The built-in laser range finder of the AGM Varmint LRF is designed to determine the exact distance
between the observer and the target. Measurement results are displayed in 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. Onboard Wi-Fi module allows live video streaming and video/image recording via
mobile applications.
