SIG SAUER ECHO RV50-LRF Thermal Riflescope 2.5-20X

The SIG SAUER ECHO RV50-LRF is a purpose-built thermal riflescope engineered for extended detection and identification in low-visibility conditions. It pairs a 50mm objective with a 640×512 thermal sensor and a wide 2.5–20X magnification range to support precision observation and target assessment. An integrated laser rangefinder and BDX 2.0 connectivity provide real-time range and ballistic data for field use.

Key Specifications

• Magnification range is 2.5–20X to cover both wide-field observation and higher-magnification tasks.
• Objective lens diameter is 50mm to maximize thermal collection for extended detection distances.
• Thermal sensor resolution is 640 × 512 for enhanced image detail compared with lower-resolution cores.
• Frame rate operates at 50 Hz for smooth thermal imaging and tracking of moving subjects.
• The thermal core specification is 12 µm with <20 mK sensitivity for improved thermal contrast.
• An integrated laser rangefinder provides 1000-yard ranging capability for on-demand distance data.
• BDX 2.0 enabled with Applied Ballistics Ultralight to deliver onboard ballistic solutions.
• Runtime is rated at 12 hours for extended field operation on internal power plus one 18500 cell.
• Video recording capability is provided with onboard video recording and streaming.
• Weight is listed as 34.9 oz (990 g) and the body is rated IP67 for water and dust resistance.

Designed for responsible long-range observation and field applications, the ECHO RV50-LRF brings thermals, ranging and ballistic computation into a single, rugged package. Its combination of resolution, magnification range and connectivity makes it suitable for extended stakeouts, predator management and precision observation tasks where reliable detection, clear identification and range data matter.
