SIG Sauer Echo SV50-LRF Thermal Sight 2-16x50mm

SIG Sauer Echo SV50-LRF Thermal Sight

The Echo SV50-LRF represents SIG Sauer's commitment to merging cutting-edge thermal imaging with practical shooting technology. This is a serious tool for hunters and precision shooters who demand performance in low-light and no-light conditions.

Core Thermal Performance

The heart of the Echo is a professional-grade LWIR 640x512 VGA thermal core operating at 12 microns with exceptional sensitivity of 20mK or better. This means you'll detect heat signatures with remarkable clarity, whether you're glassing terrain at dusk or working in complete darkness. The 50Hz refresh rate ensures smooth target tracking and natural sight picture.

Integrated Rangefinding and Ballistics

The built-in 1000-yard laser rangefinder eliminates the need for separate devices. Combined with BDX 2.0 enabled ballistics—including Applied Ballistics Ultralight with a complete bullet database—the Echo calculates firing solutions automatically. Environmental sensors feed real-time data into the system, accounting for temperature, barometric pressure, and angle to deliver precise holdover information.

Practical Features

• Recording capability: Capture still photos and video with audio for documentation and analysis
• Long runtime: Rechargeable 18650 lithium-ion batteries deliver 11 hours per charge
• App integration: Configure settings and download media via the BDX App
• Rugged mounting: Cantilevered Picatinny rail mount for secure attachment

The Bottom Line

The Echo SV50-LRF is engineered for shooters who refuse compromise. It simplifies the ballistics equation while delivering the thermal imaging clarity that separates success from frustration in the field.
