AGM Secutor LRF 50‑640

The Secutor LRF 50‑640 steps up from the 35‑mm model with a 640×512 VOx sensor and a larger 50 mm f/1.0 lens. This combination boosts thermal sensitivity and is rated for detection up to ~2.6 km for a human‑sized target while maintaining a generous 8.8° × 7.0° field of view. Like its smaller sibling, it integrates a 1,000 m laser rangefinder and ballistic calculator for quick holdovers and includes AGM’s sub‑20 mK thermal core, multiple colour palettes and picture‑in‑picture mode.

Power comes from four CR123A batteries for about six hours of continuous use, and recorded video and images are stored on 16 GB of internal memory or streamed over Wi‑Fi.

  • Is This the Right Thermal for You?:

    Hunters who need more reach or finer image detail than the Secutor 35‑384 provides will appreciate the 50‑640’s higher resolution and larger lens. The 640×512 sensor produces noticeably sharper images, especially when using digital zoom, and the 50 mm glass gathers more thermal radiation to extend detection range beyond ~1.5 miles. Base magnification drops slightly to 2.5×, which means you retain a broad field of view for scanning. If you rarely shoot beyond mid‑range distances or prioritise minimal weight, the smaller 35‑mm model may suffice; otherwise the 50‑640 offers a clear performance upgrade without the heft of the 75‑mm variant.

  • Best For:

    • Hunters who want the clarity of a 640×512 sensor and the longer detection range afforded by a 50 mm lens
    • Shooters who require an integrated rangefinder and ballistic solver for shots approaching ~2.5 km
    • Users seeking a balance between field of view and magnification for mixed timber and open‑field hunting

  • Not Ideal For:

    • Those who don’t need the extra reach; the 35‑mm Secutor is lighter and less expensive
    • Extreme long‑range shooters who benefit more from the 75‑mm model’s ~3.8 km detection
    • Hunters who prefer rechargeable battery packs over CR123A cells

  • How This Model Compares:

    The 50‑640 sits between the 35‑384 and 75‑640 models. It shares the same 1,000 m rangefinder and ballistic calculator but uses a 640×512 sensor for dramatically improved image detail. Compared with the 35‑384 it offers about 40 percent greater detection range and slightly lower base magnification (2.5× vs 3×). The 75‑640 increases lens size again to 75 mm and pushes detection beyond 3.8 km but is heavier and pricier. All versions share the same 16 GB memory and user interface.

    The 50‑640 improves on the 35‑384 by switching to a 640×512 detector and 50 mm lens, yielding sharper imagery and roughly ~800 m more detection range. Its base magnification is slightly lower (2.5× vs 3×) to maintain a usable field of view. Compared to the 75‑640, this model is lighter and has a wider field of view but doesn’t offer the extreme long‑range capability of the 75 mm version.

  • What You Actually Get in Real-World Use:

    In practice, the Secutor 50‑640 delivers crisp, high‑resolution thermal images that remain clear even at higher digital zoom settings. The larger lens helps you spot heat signatures more quickly, and the integrated rangefinder pairs with the ballistic calculator to speed up long‑range shots. Despite running on CR123A batteries, users report about six hours of real‑world runtime. Like other Sectors, the menu is easy to navigate and offers hot‑tracking, picture‑in‑picture and multiple colour modes. Video and audio recording to the built‑in memory is simple to start, and Wi‑Fi streaming allows remote viewing.

  • FAQS

    • What detection range does the Secutor LRF 50‑640 offer?
      Under ideal conditions the 50‑640 can detect a 6‑foot target out to about 2,600 meters. Identification distances are shorter and depend on target size and environmental factors. The built‑in laser rangefinder measures targets to 1,000 meters with ±4 m accuracy.
    • Is the image quality noticeably better than the 35‑384?
      Yes. The jump from a 384×288 sensor to a 640×512 sensor provides significantly more detail and allows higher digital zoom without the image becoming overly pixelated. The 50 mm lens also gathers more thermal energy, improving contrast in challenging conditions.
    • How long will the batteries last?
      AGM rates the 50‑640 for more than six hours of continuous operation on four CR123A batteries. Actual runtime varies with temperature and feature use, and you can supply external power via the USB‑C port for longer sessions.
    • Does it include recording and Wi‑Fi?
      Yes. The scope records video and audio to 16 GB of internal EMMC storage and features shot‑activated recording. You can connect a smartphone or tablet via the built‑in Wi‑Fi hotspot for live view and file transfer.
    • Is the ballistic calculator user‑friendly?
      The integrated ballistic solver allows you to input bullet and rifle parameters and stores multiple profiles. Paired with the laser rangefinder, it offers real‑time holdover corrections. Users find it intuitive once profiles are configured.

  • Detailed Product Description:

    AGM’s Secutor LRF 50‑640 is engineered for hunters seeking a substantial upgrade in resolution and range without stepping up to the heaviest optics. Its 12‑µm VOx microbolometer produces a 640×512 image with <20 mK thermal sensitivity, revealing fine details in complex environments. The 50 mm f/1.0 objective lens collects more energy than the 35 mm model, extending detection to roughly 2.6 kilometres while still providing an 8.8° × 7.0° field of view. You get a 2.5× optical magnification with digital zoom choices of 1×/2×/4×/8× for up to 20× total.

    AGM’s integrated rangefinder and ballistic calculator simplify long‑range shooting by calculating holdovers based on real‑time distance measurements. Ten selectable reticle styles and several colour palettes accommodate different scenarios, and picture‑in‑picture mode preserves situational awareness. Video and audio can be recorded internally, with shot‑activated capture ensuring you never miss the moment. 

    The scope runs on four CR123A batteries with a runtime exceeding six hours; a USB‑C port allows external power. With IP67 waterproofing, shock‑proof construction and a five‑year warranty, the Secutor 50‑640 is ready for serious night hunting.
