SubWave T2 Transceiver

The dive network's radio. The T2 screws onto your regulator's high‑pressure port and carries SubWave itself — every underwater message relays T2‑to‑T2 and up to the S1 buoy — while streaming your live tank pressure to every networked wrist. The watch is the screen; this is its voice.

Why a transceiver

No T2, no underwater comms — the Adventure Diving watch is the screen and the brain; the T2 is its radio in the water.

The network's radioEvery underwater message travels through the T2 — transceiver to transceiver between divers, and up to the S1 buoy for the boat — along with live distance to each diver. The watch composes; the T2 transmits.
Air, for you and your partyLive pressure for up to 8 tanks on every networked wrist — and your air time remaining, computed from your actual breathing rate and depth, decompression stops included.
Sonar that whispersSubWave runs at 1–10 W — against roughly 1,000 W for marine sonar — because sound carries better through water than radio ever will. Testing has shown no disturbance to sea life.

Pressure, liveTank pressure and air time remaining on the watch — alerts at reserve, alarms when critical.

Eight tanks, one glanceEvery T2 in your group reports in — depth, distance and air for each networked diver.
