Sig Sauer Echo MV-50-LRF 3-24x50mm Marine Thermal Monocular

SIG Sauer ECHO MV50-LRF Marine 3-24x50 Thermal Monocular

The SIG Sauer ECHO MV50-LRF Marine is a 3-24x50mm thermal rangefinding monocular designed for demanding observation on and around the water. Its 640x512 long-wave infrared thermal core, 12-micron pixel pitch, 50 Hz frame rate, and thermal sensitivity of 20 mK or better provide a high-detail thermal image for detecting vessels, shorelines, wildlife, and other heat signatures when visible-light conditions are limited.

An integrated 1,000-yard laser rangefinder, Applied Ballistics Ultralight, BDX 2.0 connectivity, eight selectable palettes, and onboard photo and video recording with audio consolidate multiple observation tools into one professional-grade handheld optic. The orange Marine exterior makes the exact variant easy to distinguish from standard black thermal monoculars.

Extend low-light and after-dark situational awareness with one integrated thermal and ranging system. Purchase the SIG Sauer ECHO MV50-LRF Marine at BattleHawk Armory.

640x512 Thermal Core with 50 Hz Imaging

The ECHO MV50-LRF Marine uses a 640x512 VGA thermal core with a 12-micron detector and 50 Hz refresh rate. Higher-resolution thermal data helps preserve detail when identifying the shape, movement, and relative position of heat signatures, while the 50 Hz frame rate supports smoother viewing when the user or subject is moving. Thermal sensitivity rated at 20 mK or better is designed to resolve smaller temperature differences, which can improve definition in difficult environmental conditions.

Magnification ranges from 3x to 24x through the 50mm system. Eight selectable color palettes let the user change the presentation to suit the scene, personal preference, and viewing task. The listed field of view is 8.7, providing the buyer with an exact reference point when comparing this Marine model with other ECHO thermal monoculars.

Integrated 1,000-Yard Laser Rangefinder

The laser rangefinder is integrated into the objective assembly, eliminating the need to carry and align a separate ranging device. It is rated for distances out to 1,000 yards under supported conditions. LIGHTWAVE DSP rangefinding technology is used to provide compact, fast-ranging capability while preserving the handheld profile.

Applied Ballistics Ultralight and BDX 2.0 expand the information available to a properly configured user. These systems are intended to support compatible ballistic workflows, but successful use depends on correct profiles, connected equipment, environmental inputs, and operating procedures. Buyers should review the current SIG instructions before relying on ballistic outputs.

Photo, Video, and Audio Recording

The ECHO MV50-LRF Marine can capture still photographs and video with audio. Recording capability gives boat operators, wildlife observers, and property owners a way to document heat signatures, routes, or events directly through the thermal view. Storage management, file transfer, and recording settings should be configured before field use so the optic is ready when documentation is needed.

Dual Battery System and 10-Hour Runtime

An internal battery works with a replaceable external 18500 battery to provide flexible power management. Rated runtime is up to 10 hours, allowing the user to plan for extended observation periods without depending on a single fixed power source. Actual runtime can vary with display settings, recording, ranging activity, wireless functions, battery condition, and ambient temperature.

Marine-Oriented Construction

The housing carries an IP67 waterproof rating for resistance to water and environmental exposure within the limits of that rating. Overall length is 7.6 inches, diameter is 2.4 inches, and weight is 19.8 ounces without the battery. Those dimensions keep the integrated thermal core and laser rangefinder in a compact handheld form that can be carried, stowed, and deployed without a separate mounting system.
