The new SIG Sauer ECHO Thermal Monocular series marks a big step forward for SIG. Designed for hunters, tactical folks, and serious outdoor enthusiasts, the ECHO range looks to deliver intuitive controls, and long lasting performance, all in a compact package.

Each model is listed as having a LWIR 640×512 VGA thermal core with a 12-micron pixel pitch and a thermal sensitivity of less than 20 mK. This means it can pick up minute heat differences, producing high contrast imagery in complete darkness or through smoke and light fog. A 50 Hz refresh rate ensures tracking of moving targets, while eight selectable colour palettes give users the flexibility to adapt to changing conditions and personal preferences.
Battery life is impressive with each monocular running for up to 10 hours on dual 18500 rechargeable lithium-ion batteries, with spares included for minimal interrupted use in the field. For those who like to capture and share their hunts or operations, the ECHO integrates with the SIG BDX 2.0 Mobile App, allowing wireless image and video capture, live streaming, and ballistic data integration for shooting.
The ECHO Thermal Monocular comes in three models:
- ECHO MV35 – 2–16× zoom, ideal for all-round observation and scanning.
- ECHO MV50-LRF – 3–24× zoom with a built-in 1,000-yard laser rangefinder and Applied Ballistics® Ultralight integration.
- ECHO MV-DV50 – 1.5–24× zoom with dual-view field of view (8.7° standard or 17.1° wide) for enhanced situational awareness.
What sets the ECHO range apart from many competitors is the combination of optical performance and practical field usability. The wide zoom ranges cater to both close-in observation and long range identification, while the rugged housing is built to withstand tough environments. If you’re glassing paddocks at night for pest control, spotting game in dense bush, or even conducting search operations, the ECHO looks like it will be worth a look.
