David "Dave" John Shaw (1954 – 8 January 2005) was an Australian scuba diver, technical diver, and airline pilot for Cathay Pacific, who flew the A330-300, A340-300, and A340-600.
Shaw's first rebreather was an Inspiration closed circuit rebreather, which he eventually dived to depths beyond the unit's supposed capability. That prompted him to purchase a Mk15.5, which he modified by removing the analogue electronics and replacing them with the Juergensen Marine Hammerhead digital electronics, in a specially modified POD designed to handle extreme pressures. The Mk15.5 was his rebreather of choice for dives deeper than 150 metres (500 ft). Shaw also owned a Cis-Lunar Mk5P that he used on extended dives in caves shallower than 150 m. He believed the Cis-Lunar had greater redundancy capabilities for such dives but could not cope with extreme depths.
On 28 October 2004, Shaw broke the following records at Bushman's Hole, South Africa:
He used a Mk15.5 with Juergensen Marine Hammerhead electronics and the following gas mixtures: trimix 4/80, 10/70, 15/55, 17/40, 26/25, air, nitrox50, 100% oxygen. The cave elevation was 1,550 metres (5,090 ft) and the dive duration was 9 hours 40 minutes.
On this record-breaking dive, Shaw discovered the body of Deon Dreyer, a South African diver who had died in Bushman's Hole ten years previously. The body was at a depth of 270 metres (890 ft).
Shaw died on 8 January 2005 while seeking to recover the body of Deon Dreyer.
