Today, I’m diving into the SIG Sauer ECHO SV50 LRF, a thermal sight that’s not just impressive for its features, but for its lifetime warranty – something unheard of in the thermal industry. From its crisp 640 sensor and built-in laser rangefinder to the seamless integration with SIG’s BDX app, this optic is built for serious hunters and shooters. I’ve field-tested it at different ranges, and while I had a few misses, the overall performance really stood out. Check out the video for the full breakdown and my honest thoughts on this new thermal powerhouse.
