Many interesting dive sites, once difficult for sport divers to reach, have become more accessible.

Mixed gases to extend depth limits more safely, and multiple cylinders or rebreathers to extend dive times, help divers reach and enjoy these sites.

BSAC has a full suite of courses to meet the demand of divers who wish to extend the range and scope of their diving.

To attend these courses you must be at least a Sports Diver and have completed the Accelerated Decompression Procedurescourse (or appropriate equivalent).
