Diving Career and Experience
Chew Poh Chang has been diving since 1991. His passion for diving sees him progress from a recreational diver to Instructor and Course Director with NAUI.

His drive to continue his education and seeking new skills and knowledge to explore beyond recreational limits lead him to cross over to IANTD in 1998 and gradually progressed to Technical Instructor level with both IANTD and NAUI Tech.

Poh Chang has been teaching for more than 14 years and has trained recreational divers, technical divers, instructors and instructor trainers. He is an instructor with NAUI, IANTD, DAN and now, UTD. His key focus is to provide safe and quality training, actively promoting UTD/Hogarthian/DIR philosophies and encourages divers to be a "thinking diver".

His diving has been mainly in exploring the deep wrecks in South China Sea, spectacular wall diving in Celebes Seas and atolls of the India Ocean around Asia Pacific region. In his leisure time, another newly developed passion is to cruise through the wrecks with his underwater scooter and documenting the wonders of underwater with his video camera.
