PADI TecRec courses are the quality benchmarks in the tec diving world due to their rigorous, yet logical, training sequence and the PADI educational materials that support them. TecRec courses are instructionally valid and have a seamless course flow that takes you from a new tec diver to one qualified to dive to the outer reaches of sport diving. Each level introduces you to new gear and procedures to extend your dive limits.

The Professional Scuba Association International is oldest technical / extended range scuba certification agencies in the world. PSAI was the first agency to offer certification at the diver and instructor levels in both recreational sport and technical diving, almost three decades before anyone else.
