Many thanks. That is the Mark Powell of 'Deco for Divers'????? Jeepers. He knows his stuff...
Didn't realise St Andrew's was open for diving yet. I'll look it up.
Take a course from diving legend Mark Powell! I consider taking TDI Extended range and Trimix courses from him as well. However, before that I need to get comfortable in drysuit diving as I always dived in wetsuit.
