I am a PADI qualified Advanced Diver but wish to pursue diving within the military, which is based around BSAC. I rang up Bovisands the other day but I've missed all their crossover courses for the year, however they gave me the name of a unit/organisation to search for on ArmyNet to find my local diving centre to try and do one there. However, I can't find the site they were on about.. Does anyone know anything about these crossover courses or how to find out about getting on one? How long is the course and is it worth doing, as opposed to just doing the BSAC ocean diver course? Any help, as always, will be greatly appreciated.
