The Sig Sauer Echo MV50-LRF 3-24x50mm Marine Thermal Monocular is built to extend your vision on the water when daylight, fog, or distance make traditional optics fall short. Its 640x512, 12 µm thermal core with a 50 Hz refresh rate delivers crisp thermal detail, while the integrated LIGHTWAVE DSP GEN II laser rangefinder provides fast, accurate distance readings out to 1,000 yards. With 3-24x magnification, onboard photo and video recording with audio, and a bright orange housing that is easy to spot on deck, this compact unit is designed for serious marine use.

Beyond simple observation, the Echo MV50-LRF Marine supports long outings with an internal battery plus a replaceable external 18500 cell for up to 10 hours of runtime. Eight selectable thermal palettes let you tailor the image to changing weather and background conditions, and IP67 waterproof construction keeps the optic running in wet, spray-filled environments. Whether you are navigating back to the dock after dark, scanning shorelines, or monitoring open water, this thermal monocular reflects Sig Sauer’s focus on practical innovation and dependable performance.
