IANTD Essentials Diving Course

The first step on the nitrox ladder, the IANTD EANx Diver program is designed to provide recreational divers with a safer breathing medium for the sport diving range. Divers may elect to dive the EANx on air tables, EANx tables or computers. This course covers the use of EANx mixes in the range of 21% to a maximum of 40% oxygen.

This course with me includes two dives on an EANx mixture of between 24% and 40% oxygen.

I am a passionate adventurer, loving being in the mountains walking, climbing, scrambling as much as I love being under the water exploring shipwrecks, mines and caverns, or in search of treasure in the depths. I am a Mountain Instructor (MIA), a Winter Mountain Leader, a Scuba Diving Instructor (BSAC, TDI, SDI, IANTD), a skipper for CAT3 waters up to 25mtr and as I’ve built this experience over time, I have written about it and published those works. In addition I am a Chartered Manager with CILT, a member of the institute of Engineering & Technology, a Fellow of the Institute of Leadership & Management and a Fellow of the Royal Geographical Society. I help people fulfill their goals in the Mountains (Worldwide), Scuba Diving (Worldwide), provide location support worldwide for the media and assist with technical and safety support whenever requested.
