Acquire Your Target in Any Condition w/ SIG ELECTRO-OPTICS ECHO1 Thermal Reflex Sight

The Sig Electro-Optics ECHO1 boasts military-grade technology at consumer-grade pricing.


Newington, NH -( SIG SAUER, Inc., the world’s most renowned name in firearms, introduces the ECHO1 Thermal Reflex Sight, the latest addition to the Electro-Optics line from SIG SAUER.

The ECHO1 is a prime example of the level of break-through innovation that SIG Electro-Optics continues to introduce since its launch in 2015.

“The ECHO1 fuses the fast target acquisition and simplicity of a reflex sight with the latest in thermal imaging technology to bring you the most innovative Thermal Reflex Sight on the market,” said Andrew York, President Electro-Optics Division at SIG SAUER. “This is a true game-changer … and just really fun to use when hunting hogs and predators. Our new ECHO1 is a whole new class of thermal sight, designed in Oregon and assembled right here in the USA.”

The ECHO 1 Digital Thermal Imaging Reflex Sight is the most advanced direct-view thermal sight in the world. Based on the newest generation of thermal imaging sensors, this digital sight offers day or nighttime predator and hog hunting, while functioning similarly to a conventional reflex sight—using both eyes open for fast and intuitive target acquisition with greatly improved situational awareness. The sight is also perfect for home defense, law enforcement, military, and search and rescue situations.

Darkness is no match for the ECHO 1; nor is dust, fog, haze or foliage. Whatever you’re seeking in whatever lighting conditions—day or night—the ECHO 1 will acquire your target’s thermal signature in just seconds. This sight has eight different display modes, including “White Hot” and “Black Hot” to enhance the display for optimal thermal image contrast against the background.
