Savox Delsar LifeDetector LD3 - Seismic and Acoustic Listening Device for Extensive Search

Used by FEMA, USAR, SUSAR and rescue teams from around the world, the Delsar Life Detector LD3 is seismic/acoustic listening device to detect and locate live victims trapped in:

  • Collapsed structures caused by earthquakes
  • Explosions
  • Landslides
  • Mine disasters or cave-ins

The Delsar Life Detector LD3 converts the entire collapsed structure into a large sensitive microphone that transmits noises from entombed victims. The seismic and acoustic sensors convert vibrations created by the live victim into audible and visual signals. The Delsar is rugged, reliable and able to withstand days of continuous use at the disaster site.
