Sonavision have produced Through-Water Voice communications for over 20 years for applications such as Saturation Diving, Tourist Submarine and Rescue Submarine. The system can be used either as a normal communications channel or as an emergency system in the event that the normal cabled communications link is broken.

The standard communication system SubCom 2000 is used in saturation diving systems, but this system is backed by a further range using lower frequencies for greater range and dual frequencies for multi-channel communication. For more detailed on these please contact info@sonavision.co.uk
