Testing the Divelink audio system Underwater at Race Rocks

Jean-Olivier Dalphond and Garry Fletcher listen to the diver Ryan Murphy, (PC Year 26) as he tests out the DIVELINK system from underwater at Race Rocks. We were able to add this underwater sound ( which is carried by sonar – up to 50 meters underwater) to live webcasts by the end of the term in April 2001.
