Rechargeable batteries provide up to 8 hours of continuous use. The PRS-275 uses a highly sensitive directional hydrophone which allows the operator to hone-in on a beacon's acoustic signal from up to 1,200 meters away (37kHz/162.5dB source). The acoustic receiver, the DPR-275, is designed to be used by a diver to depths of 200m. A separate directional hydrophone with adjustable staff assembly allows the receiver to be converted for use on a small boat or platform. When the hydrophone is pointed in the direction of an acoustic beacon, the unit generates an audio tone through a waterproof headset providing feedback for relocation. To backup the audio tone, a signal strength meter provides additional feedback to the Staff Assembly & Cables and Headphones with DPR-275 (Included with PRS-275 Pinger Receiver System) 15375 Barranca Parkway, Suite I-112, Irvine, CA 92618 949-727-9399 | [email protected] | RJ
