The BiG Scuba Podcast

In this episode Gemma and Ian chat to David Strike. Originally from the UK, David Strike learned to dive with the B.S.A.C. in 1961, since when he has worked for a major London newspaper's editorial intelligence department, served with the Royal Navy, participated in ground-breaking oceanographic research and been a grave digger, a bodyguard and an offshore commercial diver in the North Sea gas and oil fields. Since immigrating to Australia with his wife and young family, he has had an active involvement in diving as a recreational and technical diving Instructor and Instructor Certifier. Qualified on open circuit, as well as rebreathers, surface demand, and standard diving apparatus, his diving credentials include certifications from ANDI, BSAC, IANTD, PADI and SSI, as well as the legendary diving company, Siebe-Gorman.   Establishing a successful, internationally-affiliated media representation organisation while simultaneously continuing to teach diving and study for an external university degree, he was one of the first divers in Australia to embrace Technical Diving – and the first to dive recreationally with Nitrox. Selling up his media company interests in 1991, he joined the embryonic Asian Diver magazine as its first Field Editor, since when he has: assisted in the 1995 launch of the first Asian Dive Exhibition & Conference (ADEC), and the first 'Tek-Asia' Conference; served as a Board member of Dive Australia – the country's former peak diving industry body; was the co-publisher and editor of, 'Professional Diver Journal' - a quarterly magazine for occupational, military and technical diving enthusiasts; authored the world's first book on Live-aboard dive vessels, as well as a crisis management manual; contributed to a number of other diving-related training manuals, and penned several hundred articles covering all aspects of diving that have appeared in newspapers and magazines around the world.   Having travelled and dived extensively throughout the European, Asian and Pacific regions for over six decades - and in a variety of roles - Strike continues to maintain his passionate interest in an activity that has dominated his life. Previously the organiser of the internationally acclaimed OZTeK Diving Conference and Exhibition, and Singapore's, TeKAsia Conference', he is the recipient of several, 'Lifetime Achievement Awards' and a Fellow of the Explorers Club of New York.   Web: www.nektonix.com   The BiG Scuba Podcast is proudly supported by Narked at 90 – "Beyond Technical."

This week Gemma and Ian take you on location for a proper UK diving adventure! We kick things off with a shore dive at East Runton on the North Norfolk coast, exploring the famous chalk reef in around 20°C water, before heading north to the Farne Islands for three days and six dives. Join us in the Farne Islands as we explore Northern Hares, Longstone Gullys, Blue Caps, The Hopper and Gun Rock, with plenty of marine life along the way – including lobsters, crabs, dogfish, anemones, wrasse, seals, puffins and even a porpoise! We chat about changing tides and currents, the importance of having an experienced skipper, our favourite moments from the trip and why this could be our best Farne Islands trip yet. Plus, we talk about diving with family, the appeal of UK diving and why Seahouses and the Farne Islands are well worth a visit for divers and non-divers alike. 🎧 Dive in and join us on the adventure!
