AGM Secutor LRF-C 50-640

AGM Secutor LRF-C 50-640

AGM’s Secutor LRF‑C 50‑640 combines a 640×512 VOx thermal core with a 50 mm f/1.0 lens and an integrated 1,000 m laser rangefinder, allowing you to convert a day scope into a range‑capable thermal system. This clip‑on provides 1× optical magnification and maintains your existing zero. It is rated for detection up to ~2.6 km for a human‑sized target and features 1×/2×/4×/8× digital zoom, multiple colour palettes, picture‑in‑picture mode and 16 GB of on‑board storage. Power comes from four CR123A batteries for about six hours of runtime, and the unit records video and streams via Wi‑Fi.

  • Is This the Right Thermal for You?:

    The LRF‑C 50‑640 is ideal for shooters who want a clip‑on with built‑in ranging but don’t need a ballistic calculator. Compared to the Rattler‑C series, it adds an eye‑safe 1,000 m laser rangefinder and digital compass. Its 640×512 sensor provides crisp images and the ability to detect targets well over ~1 mile. Battery life is slightly shorter than the Rattler‑C models due to the rangefinder, but CR123A batteries are inexpensive and easy to find. If you prefer rechargeable batteries or don’t require a rangefinder, the Rattler‑C 50‑640 may be a better fit.

  • Best For:

    • Shooters who need a clip‑on thermal sight with an integrated laser rangefinder
    • Hunters requiring high‑resolution imaging and detection up to ~2.6 km
    • Users who want to retain their day scope’s zero and have ~6 h runtime from CR123A batteries
  • Not Ideal For:

    • Those seeking a built‑in ballistic calculator – the LRF‑C line does not include one
    • Hunters who prefer rechargeable battery packs (e.g., NE‑4400)
    • Users who seldom need rangefinding and could save money with a non‑LRF clip‑on
  • How This Model Compares:

    The LRF‑C 50‑640 differs from the Rattler‑C clip‑ons by incorporating a 1,000 m laser rangefinder and digital compass. It uses disposable CR123A batteries instead of a rechargeable pack and therefore has slightly shorter runtime (~6 h). Compared to the 75‑640 LRF‑C, it offers a wider field of view but a shorter detection range. All share the same 640×512 sensor, 16 GB memory and IP67 rating.

    Relative to the 75‑640 LRF‑C, this 50‑mm version provides a larger field of view and lighter weight while sacrificing roughly ~1.2 km of detection range. Compared to the Rattler‑C 50‑640, the LRF‑C adds an integrated laser rangefinder but uses CR123A batteries instead of a rechargeable pack.

  • What You Actually Get in Real-World Use:

    In the field, the Secutor LRF‑C 50‑640 offers sharp thermal imagery and accurate ranging from its built‑in laser. Hunters appreciate being able to confirm distance without switching devices. The clip‑on preserves the host optic’s zero and reticle, making it quick to transition between day and night use. Battery life typically is around six hours on quality CR123As, and the 16 GB memory handles plenty of video recording. Users should note that there is no ballistic calculator; you’ll need to apply dope manually or use an external solution.

  • FAQS

    • Does the Secutor LRF‑C 50‑640 have a ballistic calculator?
      No. While the unit features a built‑in laser rangefinder and digital compass, it does not include an on‑board ballistic solver. You can use the range data to make manual adjustments or input it into a separate calculator.
    • What type of batteries does it use?
      It runs on four CR123A batteries and delivers more than six hours of operation. You can also power the device via its USB‑C port.
    • How far can the 50‑640 LRF‑C detect and range targets?
      Detection range is approximately 2,600 meters on a human‑sized target. The integrated laser rangefinder measures distances up to 1,000 meters with ±4 m accuracy.
    • Does this clip‑on affect my riflescope's zero?
      No. The 1× optical configuration means your day scope's zero remains valid. You simply view your normal reticle through the thermal overlay.
    • Is it waterproof and durable?
      Yes. The unit is rated IP67 for water and dust protection and is built to handle recoil from common hunting rifles. AGM provides a five‑year warranty.

  • Detailed Product Description:

    The Secutor LRF‑C 50‑640 brings AGM’s rangefinding technology to a clip‑on platform. At its core is a 640×512 VOx detector with <20 mK sensitivity, mated to a 50 mm f/1.0 lens. The unit delivers 1× optical magnification so your riflescope’s reticle and zero remain unchanged.

    A built‑in class‑1 laser rangefinder measures distances up to 1,000 meters and displays readings on the 1024×768 OLED screen, while a digital compass aids orientation. With digital zoom options of 1×/2×/4×/8×, you can examine targets more closely without leaving your firing position. Video and audio are recorded to 16 GB of internal memory, and the Wi‑Fi hotspot enables remote viewing and file transfer. 

    Four CR123A batteries power the device for over six hours, and a USB‑C port accepts external power. Sealed to IP67 standards and backed by AGM’s 5‑year warranty, the LRF‑C 50‑640 is a versatile upgrade for hunters who need accurate ranging in a clip‑on format.
