SIG Sauer Electro-Optics introduces the ECHO3 Thermal Reflex Sight, a ultra-compact direct view thermal sight that, thanks to SIG Sauer Ballistic Data Xchange (BDX 2.0) technology, offers the capability to capture images and record video in several different color palettes.

The SIG Sauer Electro-Optics ECHO3 is available in a 1-6x or 2-12x magnification. Equipped with the BDX technology, the ECHO3 can be used with 9 different onboard SmartBDC ballistic holdover reticles or it can be paired with any KILOBDX rangefinder.
A motion activated MOTAC (Motion Activated) display powers up when it senses motion with over 6 hours of continuous runtime, offering video and image recording in several different color palettes, and six brightness settings. The ECHO3 uses an uncooled 320x240 12um VOx LWIR core operating at 30Hz (ITAR Controlled).
SIG Sauer ECHO3, “A massive improvement over traditional eyepiece style thermals”

Andy York, President, SIG Sauer Electro-Optics, explains the most interesting features of the ECHO3: “The innovative direct-view thermal display on the ECHO3 is a massive improvement over traditional eyepiece style thermals which induce eye fatigue and force the shooter to look through the sight. The ECHO3 allows the shooter to sit back and view the thermal display and when targets are identified, the new BDX reticle technology allows for exact aiming solutions in real time.”
The Levelplex anti-cant system allows for scope cant sensitivity down to 0.5°. The ECHO3 Includes a quick disconnect mount, with an easy to adjust zoom lens with throw lever attachment. In the US the SIG Sauer Electro-Optics ECHO3 Thermal Reflex Sight will be available this spring.
