AGM Secutor LRF-C 50-640 Thermal Imaging Clip-On
AGM Secutor LRF-C 50-640 Thermal Imaging Clip-On
AGM Secutor LRF-C 50-640 is a compact thermal imaging clip-on system with a built-in precision laser rangefinder, designed to convert daytime optics into a thermal setup without special tools or a full change of rifle configuration. It uses a highly sensitive 12μm VOx uncooled focal plane array sensor, 640×512 resolution, a 50 mm F1.0 lens, true 1× magnification, and a 1024×768 OLED display, which gives the user a high-detail thermal image while preserving the familiar view through the daytime optic.
A major advantage of this model is the integrated laser rangefinder with a range up to 1000 m and ±4 m accuracy. AGM states that the Secutor LRF-C can be mounted in front of rifle scopes with magnification up to 10x for medium-range use, which makes it especially practical for hunters and professional users who want exact distance data together with a true clip-on thermal workflow.
The unit is also equipped with the field features that matter in real use: onboard video and audio recording, image capture, Shot Activated Recording, WiFi hotspot, standby mode, burn prevention, defective pixel correction, highest temperature spot tracking, and 16 GB of built-in EMMC storage. Four replaceable CR123A lithium batteries provide more than 6 hours of operation, and external 5 VDC/2 A power can be connected through USB Type-C for extended runtime.
With IP67 protection, recoil resistance up to 1,000 g / 0.4 ms, and a compact 193 × 104 × 74 mm housing, the Secutor LRF-C 50-640 is built for demanding hunting and tactical conditions. For customers of Professional Optics, it is a premium clip-on solution with competitive pricing and delivery across Europe from Split, Croatia.

For experienced users, the key value of the Secutor LRF-C 50-640 is the combination of a 640-resolution thermal core and a true clip-on workflow with integrated laser ranging. This matters because the unit is built to preserve the existing daytime optic and rifle setup while adding thermal imaging and exact distance measurement in one front-mounted system.
The second major advantage is the image quality relative to the role. A 50 mm objective and 640×512 sensor give noticeably stronger image detail and longer detection performance than smaller 384 clip-on devices, while the 1× optical system keeps the clip-on function correct for use in front of a daytime riflescope.
Battery handling is also practical in the field. The use of four CR123A batteries makes replacement simple, while USB Type-C external power support gives the user an easy backup option for longer sessions or static observation.
