Many interesting dive sites, once difficult for sport divers to reach, have become more accessible with technical diving training. Mixed gases (to extend depth limits more safely), and multiple cylinders (to extend dive times), help divers reach and enjoy these sites.
Sport Mixed Gas Diver (50m) is BSAC's entry-level open circuit technical course. From there you can progress through the Explorer and Advanced Mixed Gas Diver courses, building skills and experience as you go.
