The RECCO detector emits a directional radar signal like the beam of a flashlight, so when the radar signal hits the RECCO reflector, it’s echoed back to the detector and points the rescuer in the direction of the person in danger. The closer the detector gets to the reflector the stronger the returned signal, ultimately allowing the rescuer to pinpoint the victim's location. RECCO reflectors are designed to last a lifetime and do not age or wear out—if not mechanically damaged they will last forever, so you can continue exploring the mountains without fear of failure from your rescue technology.

The RECCO reflector makes you searchable to the rescuers. RECCO reflectors are lightweight passive transponders that require no power or activation to function. They consist of a diode and an antenna. RECCO reflectors are integrated into the product. RECCO reflectors are designed to last a lifetime and do not age or wear out. If not mechanically damaged they will last forever.
