The Sig Sauer Echo SV50-LRF 2-16x 50mm Thermal Sight is a rifle-mounted thermal scope from Sig Sauer that pairs a 640×512 sensor with an integrated 1000-yard laser rangefinder (Sig Sauer part no. SOEC12310). It folds ballistic data, range and environmental readings into one sighting system, so there is no separate rangefinder or ballistic chart to juggle on a night hog hunt or a predator stand. A cantilevered Picatinny mount puts it on a rifle rail, and BDX 2.0 support ties it to the BDX app for settings and media. It is a serious option for hunters who want to see and range in total darkness.

Key Specifications

• Magnification starts at 2x with 16x digital magnification, so one setting covers a close shot and a long look.
• The thermal core is a 640×512 LWIR sensor at 12 micron pitch and 50 Hz, giving a detailed image with a smooth refresh rate.
• Sensor sensitivity is rated at 20 mK or better, which helps separate warm targets from a cool background.
• The objective diameter is 50mm, a larger lens than the SV35-LRF for gathering thermal energy at distance.
• An integrated 1000-yard laser rangefinder gives distance readings without a second device.
• BDX 2.0 is enabled and includes Applied Ballistics Ultralight with the complete AB bullet database for holdover solutions.
• The reticle comes in multiple color patterns, so you can pick the one that reads best against the scene.
• The scope records photos and video with audio to 32GB of internal solid-state storage for reviewing a hunt later.
• A cantilevered Picatinny rail mount attaches the sight to a standard rifle rail.
• The body measures 10.7 inches long and runs on a lithium-ion battery rated for about 11 hours.
