SIG SOEC32310 ECHO RV50 640X512 2.5-20X50

The SIG ECHO RV50 thermal riflescope is a premium long-range hunting and precision optic built for shooters who need to see and engage targets in complete darkness. This 2.5-20x50 thermal scope combines a high-resolution 640×512 thermal sensor with a built-in 1000-yard laser rangefinder, giving you detection, identification, and accurate distance data in a single system—day or night, rain or shine.

At its core is a LWIR 12-micron thermal engine running at 50 Hz with less than 20mK sensitivity, meaning you'll spot game and warm targets at extended distances where conventional optics fall short. The 50mm objective lens maximizes light gathering and detection range, while the 2.5-20x magnification covers everything from close-quarters predator work to serious long-range rifle shooting. The integrated rangefinder feeds real-time distance data to your firing solution without fumbling for a separate device.

This scope is fully BDX 2.0 enabled, which means it connects to your phone and other systems for live video streaming and recording. Pair it with Applied Ballistics Ultralight software and you get verified ballistic solutions tailored to your rifle, ammunition, and atmospheric conditions—no guessing, no holdover charts, just shoot-to numbers when you need them. Built tough to IP67 waterproof standards, the RV50 weighs 34.9 oz and runs for 12 hours per charge, making it practical for extended overnight hunts or predator management operations.

Whether you're hunting coyotes at midnight, doing long-range validation on the range, or running a serious predator-control program, the ECHO RV50 thermal riflescope delivers the glass and features that turn darkness into advantage.

Frequently Asked Questions

Is the SIG ECHO RV50 thermal scope compatible with BDX ballistics software?

Yes. The RV50 is fully BDX 2.0 enabled, which allows it to integrate with Applied Ballistics Ultralight software and connect to your smartphone for live video streaming, recording, and ballistic solution sharing. This integration is ideal for shooters who want verified, real-time shooting solutions for long-range work.

What kind of battery life should I expect on a hunting trip?

The ECHO RV50 has a 12-hour internal battery runtime, which is designed to support extended overnight hunts and multi-hour operations. It uses an internal battery plus one additional 18500 battery for backup or extended use.

Can this thermal scope be used in wet or harsh weather conditions?

Yes. The RV50 carries an IP67 waterproof rating, meaning it's sealed against dust and can handle submersion in water up to 1 meter for 30 minutes. This makes it suitable for rain, snow, and wet field conditions typical of hunting and predator-management work.

What makes the 50mm objective lens important for thermal imaging?

The larger 50mm objective lens maximizes the thermal sensor's ability to gather infrared energy from distant targets, which directly improves detection range and identification clarity. This is particularly valuable for long-range hunting and extended-distance predator work where spotting warm targets at maximum distance is critical.
