The Sig Sauer Echo SV50-LRF is what happens when a company that builds fire-control systems for the military decides to make a hunting thermal: a 2-16x50mm sight with an integrated laser rangefinder and BDX 2.0, Sig's ballistic ecosystem that talks to your phone and drops a corrected aim point onto the display. Range the animal, get the dot, press the trigger — the workflow is closer to a guided system than a traditional scope.

For shooters already running Sig BDX rangefinders or KILO binos, the Echo SV50 slots into the ecosystem you own. Thermal optics ship direct to your door with no FFL transfer required.
