Yesterday, December 5, 2009, a team of 3 divers using rEvo rebreathers succesfully completed a dive to 211m at Panorama Reef in the Egyptian Red Sea.
Local support, gasses, tanks, boats, staff (in and out water) was supplied by Orca Dive Clubs.
The dive was permitted by and had the support of the Egyptian Chamber of Diving and Watersports and had the support of Hypermed, the hyperbaric chamber of Hurghada.

Hyperbaric chamber stand-by: Dr Hossam Nassef (Egypt)
Gear and gasses
Hybrid standard rEvo III in cmf mode (Paul)
Hybrid standard rEvo II in cmf mode (Marco)
mCCR mini rEvo III (Pim)
Inboard dil 5/75
Offboard dil 10/70
PPO2 adjustment by injecting rich dil 10/70 in the deepest part of the dive (200m-100m)
Bailout gasses 5/75 10/70 15/50 20/30 50 O2
Deep lights provided by Green Force.
Dive organisation
Planned depth 210m, bottom time 1 minute, run time 280 minutes.
Deco profile according to the Shearwater computers on the rEvo’s.
Descent speed 20m/min, ascent speed from depth till first stop (95m) 20m/min.
Deep shot line from boat 1 +/- 50 m away from the reef, jump at 50m depth to shallow shot line from boat 2 near the reef to finish the dive.
Full deco station under boat 2 with all gasses at 12/9/6m
Deep divers carrying 80cft 5/75, 10/70 and 15/50 bail-out gasses, and one extra 40cft oxygen in case of loss of inboard oxygen.
Deep support divers carrying 80cft 15/50, 20/30 and 50%.
Shallow support divers bringing down 20/30 and 50% for the deep divers and taking off the deep mixes.
Paul and Marco using scooters to go down, Pim descending on the shot line. Parking scooters at the 180m mark (max scooter depht) and going to the end mark on the line. Ascending on the shotline till first stop, after recovering the scooters on the way up.
The Dive:
The entire dive went according to plan, except for a part of the ascent, where Pim switched over to open circuit gas as he felt unsure, probably due to overexertion during the descent in trying to keep up with the planned descent speed. After assessing the situation, Pim switched back to the rebreather.
The last 3 hours of the dive were spent on the nice reef of Panorama, near the support boat with the decostation. The deep divers, support divers and all together, enjoining the marine life and Marco filming ‘anemone city’.
The last diver left the water on runtime 294, and after 10 minutes surface deco the complete dive plan was finished.
Local support, gasses, tanks, boats, staff (in and out water) was supplied by Orca Dive Clubs.
