135 divers simultaneously breathed on a single SCUBAPRO MK25 first stage regulator during the celebration of SCUBAPRO’s 50th anniversary on June 23, 2013. A standard, out-of-box SCUBAPRO MK25 first stage was used for the record dive. The 135 participants included local Korean divers, a few overseas divers, three disabled divers and seven junior divers. The record dive was supported by Marine Bank, representatives from the Korean Dive Industry, and Korean dive training agencies and event sponsors G-Scuba, Seaman and KDEC (Korea Diving Educational Council). The official time keeper was Jae-Hoon You from the law firm of Guhwa and Associates. 135 SCUBAPRO R-series second stages were rigged through a hose and manifold system and connected to the turret of a single SCUBAPRO MK25 first stage. The entire regulator system was fed by six 45L-storage cylinders and two twin 11L cylinders. Approximately 65,000 litres of air were available to supply the divers for two attempts at the new record. The system supplied the 135 divers with air for over 10 minutes from the one SCUBAPRO MK25 first stage.
