It’s one of those gadgets that you don’t think you need—until you see it in use. That’s what happens when you try the new SIG Sauer Electro-Optics ECHO1 Thermal Imaging Reflex Sight. 
The sight, which uses temperature levels to provide clear target imagery regardless of light conditions, functions like a conventional reflex sight but with greatly improved situational awareness—out beyond 1,000 yards. The ECHO1 can even take pictures in individual and burst modes for downloading. A color LCD displays white hot, black hot, and multiple temperature settings. To learn all of the features of the ECHO1, watch this SHOT Show 2017 video, or go to sigsauer.com.
