AGM Secutor LRF 75-640

The AGM Secutor LRF 75-640 expands AGM’s rangefinder equipped thermal line with a big 75mm objective aimed at longer range and more tactical work. Built around a 640 sensor and a beefed up 1000 meter laser rangefinder, it adds a digital compass and a familiar CR123A power system. For hunters, law enforcement, and defense users who need reach and reliability, the AGM Secutor LRF 75-640 is built to deliver.

What It Is and Who It Is For

The Secutor line is aimed at more tactical, non commercial applications while remaining perfectly capable in the field. This 75-640 model wears the largest objective in the group, so it gathers the most light and reaches the farthest for both ranging and detection.

The addition of a CR123A based power system gives users battery familiarity and easy resupply, an advantage on extended operations. Built by AGM, the Secutor LRF partners an embellished 1000 meter rangefinder with a digital compass for real situational awareness.

Specifications Worth Knowing

The 75mm objective defines this model, feeding the 640 core the light it needs to range and detect at distance. On the AGM Secutor LRF 75-640, the new sub-20 mK thermal sensor increases both ranging capability and the ability to distinguish heat signatures in demanding conditions.

Pairing the extended range of the laser rangefinder with the widely available CR123A power system makes this a practical choice for professional users who cannot afford proprietary battery headaches. The integrated digital compass adds a layer of awareness that hunters and tactical operators alike will appreciate.

Built for Professional Use

The 75-640 sits at the reaching end of the Secutor line, and its big 75mm objective is the reason. That large lens gathers the most light in the family, extending both detection and ranging so you can identify and engage at distances that matter in tactical and open country work. It is the model to choose when range is the priority.

The CR123A power system is a deliberate nod to professional users who value batteries they can find anywhere and stockpile without worry. Paired with the extended rangefinder and the built in compass, it makes this optic dependable for law enforcement, defense, and serious hunters who cannot afford to be caught without power or orientation.

Everything about this configuration points toward reach and reliability under pressure. If your work or your hunting takes you into wide terrain where distance and dependable power are non negotiable, the largest Secutor is built for exactly that role.

Round out the build with quality rings or a rugged mount rated for the recoil of your platform, and take a few minutes the first night to confirm the rangefinder readings against a known distance. A little preparation up front pays off with fast, confident shooting when it counts, and it keeps this large optic performing exactly the way it was designed to.
