The DRS-100B Diver Recall – Hydrophone system is U.S. Navy approved and used by Special Warfare units around the world. The DRS-100B is a dive supervisor’s best friend, allowing him to recall free-swimming divers. It will alert all divers within range with either voice, solid or intermittent tones. The DRS-100B also offers a listening mode which is great to hear marine biological and/or man-made noise.
The system comes complete with a high-quality hand-held microphone, transducer with 25′ of cable, rechargeable batteries, battery charger and main electronic unit. The DRS-100B is a must of all diving operations!
