AGM Secutor LRF-C 75-640 Thermal Clip-On

AGM Secutor LRF-C 75-640 combines a 640x512 thermal sensor with a 75mm objective and 1x base magnification. It adds a built-in laser rangefinder.

What this model does well

Adding thermal capability ahead of a compatible day optic while retaining its familiar reticle. The 5.9° × 4.7° (H × V) field of view describes how much scene appears at the starting optical view. A wider view helps cover ground; a narrower view puts more of the sensor on a smaller part of the scene.

Magnification and image detail

Base magnification is the starting optical view. Increasing digital magnification crops and enlarges sensor information; it does not add native pixels. Match the starting view to your typical distance and the space you need to follow a moving animal.

This is a front-mounted clip-on rather than a replacement for the daytime scope. Check the host scope, mount alignment and rail space as a system. Confirm zero and function with the actual assembled setup; a generic fit claim is not a substitute for that check.

Integrated ranging

The built-in laser rangefinder is rated to 1094 yards (1000 m) under suitable conditions. Reflectivity, weather and target size affect ranging. A measured distance is not an identification distance or a promise of a usable shot.

Specifications

Runtime is an “up to” manufacturer figure. Temperature, recording, wireless functions and battery condition change actual operating time.

Is it the right fit?

Best for: Adding thermal capability ahead of a compatible day optic while retaining its familiar reticle.

Consider another setup if: An unverified day-scope/rail combination; check mounting height, clearance and supported magnification.

Common question

What should I compare before choosing AGM Secutor LRF-C 75-640?

Compare native sensor resolution, base magnification, field of view and your normal viewing distance. Maximum digital magnification alone does not describe usable detail.
