The Ocean Reef M100 Portable Transceiver Surface Unit is a compact, belt-worn communication device designed for scuba diving operations. Its pocket-sized form sits comfortably on the operator’s belt, similar in size to a cellphone, and enables seamless interaction with divers in action. The unit features a PTT button and a headphone/microphone connector for clear, hands-free dialogue during diving, with an automatic on/off function that simplifies power management. With a 10-meter transducer cable, 1-channel operation, and up to 9 hours of battery life, it delivers reliable, practical scuba gear communication within a 200-meter range.

Engineered for straightforward integration with standard diving gear, the M100 supports quick setup and dependable performance in dynamic environments. Its compact design reduces bulk on the surface, while the built-in controls and connectivity keep operations smooth and efficient for professional divers.
