      A new way to find missing people

      Many people have opinions about Recco. The latest news is a device attachable to a helicopter for fast search over big areas.

      The Recco SAR Helicopter Detector is a missing person search device to search wide areas fast for people equipped with Recco Rescue Reflectors. The detector is attached to the helicopter with a sling and carried as a hanging load.

      Functional principle
      The Recco detector transmits a directional radio signal that is reflected by the Recco rescue reflector. The detector operator perceives the reflected signal as a tone, and the closer the detector gets to the reflector, the stronger the signal/tone.

      Search Parameters
      The search parameters are very dependent on the terrain, weather, vegetation and the surface structure. Therefore, only an approximate indication of the average search parameters can be given:

      • Height: approx. 100m
      • Speed: approx. 100 km/h
      • Search corridor width: approx. 100m

      Search performance at average search parameters = 6 minutes/km2
