The Delsar LifeDetector 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.
Easy-to-Read Clear Display Panel expandable with up to 6 Sensors.
