With the SDT340 or the ULTRAChecker, the AIRSense can be used for close and mid-range airborne ultrasound and is compatible with the precision indicator set as well as the Extended Distance Sensor.
AIRSense is an optional accessory for both ultrasound devices. This new sensor adds a mid-range solution for airborne ultrasound detection for both the SDT340 and ULTRAChecker (FLEX2 for short range and ParaDish2 for long range with SDT340 only). The AIRSense detection range varies from 0-20 feet/0-6 meters and up to 50 feet/15 meters when the EDS cone is attached.
