The ECHO3 is a direct-view thermal weapon sight that combines the latest thermal imaging tech with a full range of features for the modern hunter and shooter. Capable of operating day and night, the ECHO3 works like a classic reflex sight, using both eyes open for target acquisition and maximum situational awareness-so it's perfect for home defense and tactical use too. It's a fully capable standalone thermal unit, with multiple color palettes and reticles, motion activation, and onboard video/image recordinga |but the "magic" is its ability to interact with other BDX-enabled devices. Pair the ECHO3 with any KILO Series Rangefinder, and the KILO will feed ballistic data directly to the ECHO3 to give you the right ballistic hold to get on target. The ECHO3 is made in America to the highest manufacturing standards, with an aircraft-grade aluminum housing that can handle regular use and abuse in the field. Premium glass, a 10Adeg field of view, and up to 6x digital zoom show you the action in outstanding clarity. And IPX4 waterproof construction keeps the ECHO3 operating in any environment. Day or night, the ECHO3 delivers the best in thermal capability with all the features you want.
