technical or recreational???

Hi Angela, the term "technical" usually refers to diving in overhead environments, deep or long dives with decompression, or diving with multiple gases. You can get certified as a technical trimix instructor just as you can get certified as an open water instructor. Both certifications allow you to work as a professional trainer (along with the proper insurance).

A diver with "technical" training cannot work on underwater welding, repairing dams, or underwater demolition. Those types of jobs are handled by divers with "commercial" training. Some dive shops can provide commercial training.
