Savox Delsar LifeDetector LD3 Mini - Compact Seismic/ Acoustic Listening Device for Hasty 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 Mini is a two sensor seismic/acoustic listening device designed specifically for hasty searches. This compact kit can be quickly deployed on the rubble pile to convert the entire collapsed structure into a large sensitive microphone that transmits noises from entombed victims. Utilizing the same features and functionality as the Delsar LifeDeterctor LD3, the Delsar Mini is equipped with two sensors, two seismic sensors and one acoustic sensors.
