SIG SAUER ECHO RV35 2-16x35mm Thermal Riflescope

SIG SAUER ECHO RV35 Thermal Riflescope

The SIG SAUER ECHO RV35 is a high-resolution thermal riflescope designed to balance detailed target identification with practical maneuverability. This exact black model, manufacturer part number SOEC32200, combines a 640 x 512 thermal sensor, 35 mm objective lens, and 2-16x magnification in a traditional riflescope-style housing. It is built for hunters and shooters who need dependable thermal visibility across changing terrain without moving to the larger size and weight of a 50 mm system.

High-Resolution Thermal Detail

The ECHO RV35 uses a 640 x 512 long-wave infrared thermal core with a 12-micron pixel pitch, 50 Hz frame rate, and sensitivity rated at less than 20 mK. This combination is engineered to deliver a detailed, fluid image that helps the user distinguish an animal or other heat source from vegetation, ground cover, and background terrain. The higher-resolution sensor also preserves useful detail as digital magnification increases, supporting more confident observation and identification at distance.

Versatile 35 mm Optical System

A 35 mm objective provides a useful balance between field of view, reach, and overall handling. The listed 12.5-degree field of view supports scanning and situational awareness, while the 2-16x magnification range allows the shooter to transition from locating heat signatures to taking a closer look. Eight selectable color palettes let the display be adapted to the scene, target type, and the user’s viewing preference. Focus and menu controls are positioned for direct access while the optic is in use.

BDX 2.0 Connectivity and Recording

BDX 2.0 support adds wireless system configuration, live streaming, and recording capability. Users can configure compatible functions through SIG SAUER’s connected ecosystem and capture thermal video without attaching a separate camera to the rifle. Recording can be useful for reviewing a hunt, documenting observations, or evaluating equipment and technique after a range session. The optic should be configured and familiarized at the range before field use so controls, display settings, and reticle selections can be operated efficiently.

Riflescope-Style Form and Controls

The ECHO RV35 uses a 30 mm maintube and a layout intended to feel familiar to shooters accustomed to conventional riflescopes. Its listed dimensions are approximately 14.8 inches long, 3.5 inches high, and 2.8 inches wide, with a weight of 31.07 ounces. The black housing carries an IP67 waterproof rating, providing protection against rain, dust, and demanding outdoor conditions. A standby setting can turn off the display to conserve power and reduce visible light while allowing rapid return to operation.

Extended Battery System

A rechargeable internal battery works with one removable 18500 battery to provide a listed runtime of up to 12 hours. The scope draws power from the removable cell first, then automatically changes to the internal battery when the external cell is depleted or removed. This arrangement allows the removable battery to be replaced without shutting down the optic. The internal battery charges through the USB-C connection, while the external cell can be charged in its compatible charger.

Balanced for Field Use

The ECHO RV35 occupies the versatile middle position in SIG SAUER’s ECHO R thermal riflescope family. Its 640 x 512 sensor and 35 mm objective emphasize identification and image fidelity, while the 2-16x range and 12.5-degree field of view support both scanning and closer examination. For predator management, nighttime observation, and other lawful thermal-shooting applications, it offers a capable blend of resolution, runtime, connectivity, and manageable size. Always follow applicable laws, confirm a safe target and background, and read the owner’s manual before mounting or operating the optic.
