On the 18th of September 2014, an Egyptian diver, Ahmed Gabr, descended in the Red Sea to a depth of 332.35m, setting a new World Record for the Deepest Scuba Dive. The dive took place in Dahab with the help of H2O Divers and a team of 30 people including 9 divers, technicians and medical staff.
The diving plan aimed to reach 350m deep; however, due to the symptoms of HPNS (high-pressure nervous syndrome) which began to occur below 320 meters, Ahmed decided to start his ascent.
The total diving time amounted to 13 hours and 50 minutes, with decompression stops totalling 13 hours and 35 minutes! Ahmed Gabr took into account problems he expected to face during decompression that had been experienced at previous record-breaking dives performed by other teams. Such a deep dive requires many hours of decompression, and a heavy set of cylinders on your back interferes with blood circulation and puts significantly more strain on the body. Therefore, the standard backmount configuration was used only at the initial stage of decompression. Ahmed then exchanged the heavy gear for a sidemount configuration with the STEALTH 2.0 harness. This provided incomparably better comfort and freedom of movement during the many hours of decompression.
The majority of the support team members also used a sidemount configuration. The main reason for this decision was the considerable comfort offered and no difficulty with quickly changing cylinders - factors which have significant impact during such an intensive dive.
The record was recognised by Guinness World Records in two categories: the Deepest Scuba Dive (Male) and the Deepest Scuba Dive in Sea Water.
