Sig Sauer Soec42310 Echo Mv50-Lrf Thermal Monocular 3-24X50Mm 640X512 12 Mi

The Sig Sauer Echo MV50-LRF thermal monocular brings professional-grade heat imaging and rangefinding to hunters, tactical shooters, and field operators who need to work in complete darkness without compromise. Built around a 640×512 thermal core with 12-micron sensors and 50Hz refresh rate, this compact thermal monocular delivers the sensitivity and resolution to identify game and targets reliably when ambient light fails. The <20mK thermal sensitivity means you'll spot warm targets against cold backgrounds with clarity that matters when the shot counts.

Whether you're glassing from a ridge at midnight, conducting a precision hunt in adverse conditions, or training after dark, the Echo MV50-LRF combines thermal imaging with integrated rangefinding—a 1000-yard laser rangefinder built in—so you get distance and temperature signature in one tool. The 3–24× digital zoom lets you switch between wide situational awareness and tight magnification for positive target identification. Eight color palettes give you flexibility to tune the display for your eyes and lighting conditions, and the whole package is rugged enough for serious field use.

The real innovation here is the ecosystem. The monocular pairs with Sig's BDX 2.0 mobile app to stream images and video in real-time, and when you mount a compatible ECHO thermal riflescope alongside it, the two optics talk to each other—the rangefinder and Applied Ballistics Ultralight software compute your hold automatically and display it on the scope's reticle. That's serious efficiency in low light. Runtime isn't an afterthought either: the Echo MV50-LRF runs 10 hours on its internal reserve cell plus a removable 18500 lithium-ion battery, and you get two batteries in the box so one always charges while you hunt.

Frequently Asked Questions

Can the Echo MV50-LRF communicate with a thermal riflescope?

Yes. When paired with a compatible BDX-enabled ECHO thermal riflescope, the monocular's rangefinder and ballistics solver (Applied Ballistics Ultralight) send holdover solutions directly to the scope's reticle, removing the guesswork from your shot in low-light hunts.

How long does the battery last on a single charge?

The Echo MV50-LRF delivers a 10-hour runtime using its internal reserve cell and removable 18500 lithium-ion battery. Two rechargeable 18500 batteries are included, so you can keep one charging while you use the other afield.

What recording features does this thermal monocular have?

The Echo MV50-LRF captures both photos and video with audio. Images and video can be viewed and shared in real-time through the BDX 2.0 mobile app, making it easy to document your hunts or share field intelligence.

What does the integrated rangefinder do?

The built-in 1000-yard laser rangefinder measures distance to your target and feeds that data into Applied Ballistics Ultralight, which calculates the ballistic hold you need. If you're using a compatible ECHO thermal riflescope, that solution appears on your scope's reticle automatically.
