Emergency through water communications for diving bells and manned submersibles is of importance. The Nautronix Emergency Communications System is designed specifically for this purpose. Comprising a surface and bell/submarine unit, each with full hemispherical beam transducer, and battery backup capability, the Nautronix Emergency Communications System is the ideal choice.

Based on single sideband (SSB) acoustic telemetry to provide minimum background noise, and available in 8.0875 and 25 KHz models, the system is easy to install, and the compact bell unit utilises minimal valued space inside the divng bell. The Nautronix Emergency Through Water Communications provides a reliable and essential link between the bell and mother vessel or divers.
