I will be holding a free seminar on recreational backmount doubles this saturday 11 May at 1 PM at Blue Lagoon Huntsville. This is part of a backmount doubles orientation / course that I am conducting that day. In this seminar, I will be going over the basics of diving with both manifolded and independent backmount doubles. This is for divers interested in carrying more breathing gas using backmount doubles. It does not include any technical diving decompression content. Interested people are welcome to also observe the skills conducted during the session / dive. Time permitting, divers can also try on a pair of doubles. Contact us at divezonescuba@yahoo.com if you are interested in attending.
