Tech Dive Crew
Our technical training team is comprised of skilled and experienced individuals who excel in their own field of expertise. No one can train divers to do everything, with that we have specialists who focus on their own personal interest in the area they're responsible for.
Our team work and live in a very small community of technical deep diving explorers who's main goal is to train and expose divers to this ever growing style of deep water exploration and advanced scuba industry education.
We provide technical diving in English, French, German, Spanish, Swedish, Thai and Japanese.
