Using the UWB technology (Ultra Wide Band), it interrogates the sub-surface that allows identifying the victim's location by detecting : 

  • Irregular movements, such as finger movement,
  • Regular movements, such as chest movements from breathing.



  • Compact and lightweight

Functions available in search mode

  • Set minimum search depth (start) Yes
  • Set maximum search depth (end) Yes
  • Large or small movement indicator

Oscillogram function

  • An arrow is placed at the depth where movement is detected.
