Sig Sauer SOEC42310 Echo MV50-LRF 640x512 Core 3-24x50mm LRF BDX 2.0 Thermal Monocular

Leveraging decades of innovation in rugged optics and advanced sensor technology, SIG SAUER introduces the ECHO MV50-LRF — a compact thermal monocular engineered for peak performance in any environment and fully backed by SIG SAUER’s legendary Infinite Guarantee™.

At the core of the Sig Sauer Echo MV50-LRF Thermal Monocular is a powerful LWIR 640x512 VGA, 12μm, 50Hz thermal sensor with <20mK sensitivity, delivering exceptional target detection and identification even in complete darkness. Users can choose from eight selectable color palettes to optimize image contrast for any condition or preference.

Fully integrated with SIG SAUER’s BDX 2.0 Mobile App, the ECHO MV50-LRF enables real-time photo and video capture, viewing, and sharing through the BDX 2.0 platform — keeping you connected in the field.

An onboard 1000-yard laser rangefinder pairs with Applied Ballistics Ultralight to provide instant, custom ballistic solutions. When connected to a compatible SIG SAUER BDX riflescope, the Sig Sauer SOEC42310 seamlessly transmits holdover data directly to the optic’s illuminated reticle, delivering immediate, precise aiming adjustments.

Designed for extended use, the ECHO MV50-LRF offers one of the longest runtimes in its class. It operates from an internal reserve cell as well as a removable 18500 lithium-ion battery. Two 18500 batteries are included, ensuring uninterrupted performance through the longest nights in the field.
