This innovative piece of equipment not only redefines the way I approach hunting but also promises an enhanced experience that combines cutting-edge technology with practical functionality. With its compact design and a suite of impressive features, it’s clear that this thermal reflex sight is tailored for serious hunters like me.

One of the standout features of the Echo3 is its Compact Thermal Reflex Style Sight. The integration of SIG SAUER BDX technology allows me to record both video and images in eight different color palettes.
