Sig Sauer ECHO MV50-LRF | 3-24×50 Thermal Monocular | SOEC42310

The SIG Sauer ECHO MV50-LRF is a compact thermal monocular built around a 640×512 LWIR core and a 50 mm objective. It pairs a high-resolution thermal sensor with an integrated 1000 yd laser rangefinder and BDX 2.0 connectivity to support situational observation and data sharing. The unit runs on an internal reserve cell plus removable 18500 batteries and is rated for extended field use.

Common real-world applications include nighttime wildlife observation and search-and-rescue or field reconnaissance where thermal detection and range information are required. The ECHO MV50-LRF also integrates with Applied Ballistics Ultralight for ballistic solutions when paired with compatible SIG BDX-capable optics.
