ABOUT US
ProTec, short for Professional Technical and Recreational Diving, is a global training and certification organization catering to beginners, recreational divers, and dive professionals. We work together with dive instructors and dive centres promoting responsible, sustainable diving among all levels of diving business like Cave Diving Thailand,Tech Sidemount, Tec Deep Diver & Rebreather Diver .
ProTec roots lay back in the early eighties, when the founders of ProTec, among some enthusiastic deep and mixed gas divers in Austria and Switzerland, set up their way to dive beyond the sport diving limits with new rules and training to achieve maximum safety for this extreme sport at at suitable sites for open water dives and at suitable sites for overhead dives.
The journey of ProTec began as a club initiative, which later expanded to international collaboration with various technical diving organizations. In 1997, the name and logo were revamped as part of a reorganization aimed at facilitating global operations. Initially focused exclusively on technical diving, ProTec became the first technical diving organization to incorporate recreational diving into its program. This addition was met with widespread approval and marked the start of its success.
At the heart of ProTec lies its board of directors and founding members, operating as a non-profit entity. This board delegates tasks and grants rights to international partners—commercial organizations authorized to handle operational duties. Although established primarily as a technical diving organization, recreational diving was introduced within just two years, enhancing the program and achieving immediate success.
ProTec's expansion included partnerships with international diving organizations. Notably, in 2005, ProTec joined CMAS as an international federation, aligning closely with CMAS standards. Today, ProTec offers a CMAS-compliant course program alongside its globally recognized OWD/AOWD programs.
