Sig Sauer ECHO CV25 Thermal Clip-On | 1-8x25mm | SOEC22100

The Sig Sauer ECHO CV25 is a thermal clip-on optic designed to attach forward of a riflescope and provide a thermal image to the shooter without altering the host optic’s zero. It uses a 640×512 long-wave infrared (LWIR) core with a 12 µm pitch and high sensitivity for thermal detection. The unit is compact, features a quick-disconnect mount and is configurable via SIG’s BDX app for streaming and settings control.

Applications include nighttime precision shooting and nighttime wildlife observation, as well as law-enforcement and public-safety observation roles where thermal identification at range is required.
