Underwater thickness monitoring

A team of divers from the A7 Project in the UK have been using a Cygnus DIVE underwater ultrasonic thickness gauge so that they could measure the metal thickness of a century old Royal Navy submarine wreck to determine the current condition of the remains and to monitor its deterioration over time.
