DJL offer a wide range of scuba and tech diving courses, PADI open water up to instructor and everything else in between, but they also offer a range of courses called shop opps, a 4 day course which is learning how to fix and maintain scuba equipment, such as BCDs and regulators, compressor maintenance and gas blending. Being out of the water with an ear infection, I decided to take the course as I wanted to expand my knowledge of scuba equipment as well have something new to add to my diving CV.
First thing we did was compressor maintenance. This proved to be dirty work as we were learning to change the oil the tank compressor. At first I struggled a bit with the using the tools but Ed the instructor was very helpful and patient and I soon got the hang of it. We also learned how to fill the tanks and change the filter, a very handy skill for anyone looking to get a job on a dive boat.
Next we learned how to service regulators. This again is a very usefully skill to have as getting your own regulators serviced can be expensive and learning how to do it your self can save you money. We also learned how to identify and fix any problems a regulator may be having, whether it be a leaking SPGs to a wet breathing second stages. We also looked at fixing leaking tanks and how to patch up BCDs that have holes in them, two more very usefully skills to have. There is also the option of taking gas blending course, which teaches you how to mix gases for nitrox and tech diving, which I will take later in the year.
I would definitely recommend the shop opps course to anyone, especially professional divers. Skills such as the ones you learn over the 4 days are incredibly valuable and many dive companies will look for it on a CV.
