RJE's extensive background allowed it to design a diver pinger receiver that will provide years of operation with a minimal amount of maintenance. Using digital signal processing, the DPR-275 can track and locate any underwater acoustic beacons operating between 5 to 80 kHz. Rechargeable batteries provide up to eight hours of continuous use. A highly sensitive directional hydrophone allows the diver to hone-in on a beacon's acoustic signal from up to 1,200 meters away (37kHz/162.5dB source). Large control knobs allow the operator to access the DPR-275's functions, even with thick gloves. When the DPR-275 is pointed in the direction of an acoustic beacon, the unit generates an audio tone through an underwater headset providing the necessary feedback for relocation. To backup the audio tone, a signal strength meter provides additional feedback to the location of the beacon. The DPR-275 includes an underwater headset, battery charger, and storage case. RJE International has been supplying both military and commercial customers worldwide with acoustic receivers to assist in locating and recovering assets underwater for over 25 years.
