Ocean Reef Alpha Pro X-Divers

The Ocean Reef Alpha Pro X-Divers is a hardwired, full-duplex underwater communication system that lets a surface operator talk with one or two divers at the same time, built for commercial and technical diving. The set includes an underwater unit, a surface unit, and a professional 50-meter cable, and it connects to professional Ocean Reef masks through the Ocean Reef Extender Frame.

Who it is for

This system is designed for professional and commercial diving teams that cannot compromise on clear, hands-free, full-duplex communication between a tender on the surface and divers below. Because it is a hardwired, cable-based unit, it suits commercial and technical diving operations where a tethered connection is standard.

Key details

• Full-duplex communication lets both sides talk and listen simultaneously, with powered volume control adjustable from the surface unit.
• The surface unit has 2 ports for two communication cables, a switch to talk with diver 1, diver 2, or both, a microphone, incorporated speaker, and an optional headset port.
• The professional cable included measures 50 meters, with a 10mm diameter, 4000+ Newton resistance, a 6-pin waterproof rubber connector at the diver end, and a DIN metal connector at the surface end; cable length can be customized up to 200 meters on request.
• The surface unit runs on a 12V rechargeable battery with 24 hours of standby autonomy.
• The surface unit offers audio/video recall, while the underwater unit has an audio recall button that looks like a push-to-talk button.

Compatibility and sizing

The underwater unit is engineered to pair specifically with the ALPHA PRO X DIVERS surface unit, though it can be purchased separately. It connects to professional Ocean Reef masks via the Ocean Reef Extender Frame; masks such as the Neptune III are not included and must be purchased separately.
