Product Information
The Ocean Reef M105 Digital DC Transceiver Surface Unit is a dual-channel surface communication unit for dive operators and instructors who need to run two separate communication lines from the surface at once, switching between them with a single button press. It carries the same core features as the Ocean Reef M105 Digital, with a second transceiver channel added for managing multiple groups or lines of divers.
Who it is for
This surface unit suits dive centers, training operations, and surface support teams that need to keep two distinct communication channels open, for example when supervising two separate groups of divers or running instructor and student lines side by side. The surface operator switches between the two channels by pressing a button.
Key details
- Dual transceiver channel, switchable by button for two independent communication lines
- Built-in speaker, headphone connection, and volume control for monitoring communications
- Water-resistant case with a pressure compensation valve
- LED battery tester that displays the power status of the battery at a glance
- Manufactured by Ocean Reef, an ISO 9001 Quality Management certified manufacturer
