Campbell runs Big Blue Tech, the technical side of Big Blue Diving on Koh Tao, which describes itself as a multi-award-winning TDI five-star technical centre. Students who trained there say the certifications are earned rather than rushed — one writes that "anyone training with Andy Campbell and the Big Blue Tech team truly earns their certifications, and has done so safely" — and another did TDI Advanced Wreck with him. Students on the centre's technical internship describe the operation he runs as smooth from start to finish.
