Sig Sauer Echo CV25 Thermal Clip-On 1-8x25mm 640×512

Description The Sig Sauer ECHO CV25 is a compact thermal clip-on optic designed to add thermal capability to compatible daytime optics for low-light observation and target detection. It pairs a 25 mm objective with a LWIR 640×512 core that operates at 50 Hz and offers high thermal sensitivity for consistent detection performance. The unit includes a Quick Disconnect Picatinny mount and supports BDX 2.0 for configuration and live video streaming. The eyepiece is optimized for parallax-free clip-on use and the 1024×768 AMOLED microdisplay provides a clear, high-resolution image. Key Specifications Magnification range is 1x to 8x for flexible observation at varying distances. The objective lens measures 25 mm. The thermal core is a 640×512 VGA LWIR sensor with a 12 µm pixel pitch and 20 mK sensitivity. The sensor operates at a 50 Hz frame rate for smooth thermal imagery. The eyepiece and microdisplay provide a 1024×768 AMOLED image and a 17° FOV. Power is supplied by a removable 18650 lithium‑ion battery with a stated 9‑hour runtime on a single charge. The housing carries an IP67 ingress protection rating for use in challenging environments. The optic supports BDX 2.0 connectivity and can record still photos and video with audio. Mounting is provided via a Quick Disconnect Picatinny interface for rapid attachment and removal. The optical centerline is an industry standard 1.535 inches. Engineered to integrate with existing optics and field workflows, the ECHO CV25 offers a compact, app-enabled solution for professionals and sportsmen who need reliable thermal observation. Its modular mounting, removable battery, and recording capabilities make it practical for extended outings, documentation, and situations where thermal detection improves situational awareness.
