To ensure balance, it is important to mention DSAT. DSAT is the technical arm of PADI, their TecRec courses are aimed at offering training beyond the recreational limit (i.e. more than 40m depth).
Similar to the recreational program, DSAT TecRec is split into small modular training session, aiming to extend your capability in small controlled steps.The training starts with using technical equipment to the recreational limit (i.e. 40m) and then extendeding the depth. PADI / DSAT now also offer Rebreather training in their progression ladder, which is aligned to the recreational limits (18m, 30m and 40m).
