SubVox Topside: Whole-Crew Surface Link
One station
Every diver connected
SubVox Topside is a battery-powered surface station that reaches any size dive team by voice, up to 1000 metres out.
What it does
- Two-way voice, unlimited team size — the operator and every diver on the shared channel speak freely, up to 1000 metres apart, with no shifts to schedule and no wait to connect
- Eight-channel interference control — the supervisor matches the station's channel to the dive team's units, so other stations working nearby don't cross-talk
- Standalone, battery-powered operation — the station runs on its own power, with no vessel electrical connection needed
Distinctive features
- 3000+ charge-discharge cycles — long service life before replacement
- −10 to 50 °C operating range — reliable from Arctic dives to tropical heat
- High-sensitivity receiver — picks up faint transmissions at range
- Built-in voice activity detector — distinguishes speech from background noise
- Compatible with OTS, Ocean Reef and similar systems — shares the frequency bands most underwater telephones use
- Shockproof, IP67-rated case — sealed when closed, for transport and storage
- 2 kg, one case — no cranes or deck gear to bring aboard
SubVox Topside is the surface voice every dive team needs, built for conditions where consumer equipment fails. It runs on its own LiFePO4 battery for up to 20 hours in reception mode, rated to operate from −10 to 50 °C, while a submersible antenna does the actual listening over the side and the case stays on deck. Eight channels keep it clear of every other team working the same stretch of water, with no cap on how many SubVox Diver units can share the one assigned to this team. Because it uses the same frequency bands as OTS and Ocean Reef gear, it drops into a dive team's existing setup instead of replacing it. One station. Every diver on the line. No shifts to schedule.
