The Sig Sauer ECHO SV 1.5-12X35MM is a versatile thermal sight built for hunters and precision shooters who need reliable heat-signature imaging in complete darkness. This is a purpose-built thermal optic with genuine magnification range and ballistic calculation smarts, not a budget gadget—it pairs serious glass with integrated rangefinding and on-board applied ballistics to help you make ethical, informed shots in low-light and no-light conditions.
The core is a 640x512 VGA thermal sensor with 12-micron resolution and 50Hz refresh, delivering the thermal clarity that separates working optics from novelties. At 1.5x you get wide field awareness; crank to 12x and you can identify and range game at distance. The integrated 1000-yard laser rangefinder pairs seamlessly with BDX 2.0 ballistics processing—feed it your load data and environmental conditions, and the sight calculates your firing solution. Eight color palettes let you dial in contrast for whatever terrain you're hunting, and you can record stills and video with audio to document your hunts or for post-hunt review.
Powered by two removable 18650 lithium-ion batteries with 11+ hours runtime per charge, the ECHO SV stays in the field longer than a typical hunting day. The sight is sealed to IP67 spec, so rain, dust, and the occasional dunking won't kill it. Cantilevered Picatinny mount gets it on your rifle without drama. Download and tweak settings via the BDX App, and Sig's Infinite Guarantee covers your investment for life.
Compact enough to handle—10.7 inches long, 30.5 ounces—the ECHO SV is at home on a hunting rifle or precision bolt gun. Ship includes two batteries, USB-C charge cable, flip-back lens covers, removable eyepiece, and a hard case.
