SCUBA technicians service and maintain equipment that keeps people safe and breathing underwater. The different parts work together in a highly specialised way that requires strict training and attention to detail.
Even mechanically inclined people can damage or destroy SCUBA equipment due to its intricate construction. The wide variety of gear that needs to be in proper working order -- from oxygen tanks to regulators to less well-known equipment such as compressors -- requires specific coursework to understand. SCUBA technicians are responsible for peoples' lives.
SCUBA technicians can be certified by the Association of Scuba Service Engineers & Technicians (ASSET) or the Inspectorate for Diving Equipment Servicing and Testing (IDEST). Registered IDEST technicians are specifically trained to service and test SCUBA tanks, while ASSET training covers all areas of SCUBA technology. ASSET and IDEST operate under the authority of The SCUBA Industry Trade Association (SITA).
Schools that offer ASSET and IDEST certification usually have hands-on courses in popular SCUBA tourist destinations. This allows for intensive training in all areas of SCUBA equipment servicing and testing. Online courses only allow for partial diver training.
