The DECO 60 course is a natural progression for anyone certified at the DECO 50 level and allows divers to use two optimised decompression gases to a maximum of 60 metres/200 feet. Decompression obligations are limited only by the amount of gas carried by the diver.


          Divers certify to use Normoxic Trimix with a minimum oxygen contend of 18%. Helium is based on a 30 metre/100 foot EAD/END. DECO 60 divers may use up to 100% oxygen for optimised decompression schedules.


          The program may be completed wearing back mount twin set cylinders of for those qualified as sidemount divers, in sidemount configuration.


          The program expands on the knowledge learned and the skills mastered in the DECO 50 program. The program contains the very latest techniques, protocols and technical information. The manuals use the latest graphics and are both exciting and challenging. There are three manuals that cover all the essentials for the program, they are:
          • Diving in General
          • Confined Water
          • Open Water




The main focus of the Deco 60 course will introduce the use of higher  mixtures of helium and the associated planning that comes with using  multiple gas mixes during technical dives. As with all RAID courses  your best source of information is your instructor, and they will train  and guide you through the process to attaining mastery of all skills  and theory.
