The Delsar LifeDetector 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 LifeDetector LD3, the Delsar Mini is equipped with two sensors — two seismic sensors and one acoustic sensor.
