Why a base station

The Adventure Diving watch is the screen — each diver’s T2 transceiver is the radio below, and the S1 turns the boat into part of the network.

The boat sees everyone — liveThe S1 tracks every diver's position in real time and streams it to the crew's Dive app — up to eight divers, range and tank status for each, 100 m out — without anyone surfacing to wave. After the dive, the tracks download to each diver's own app for review.
Messages through waterPreset messages travel both ways over sonar — "turn back", "start your ascent", "drop a tank" — between the captain and every networked wrist below. And when two divers lose line of sight, the S1 relays between them.
Every diver knows the way homeFind‑my‑buoy puts the distance and direction back to the S1 on every connected watch — a return‑to‑base reference when visibility drops.
