Most of what is here covers owner level maintenance and save a dive fixes: removing and replacing O-rings, freeing a stiff valve handwheel, dealing with an inflator, adjusting webbing and carrying a small set of spares. Used sensibly they save dives. What they do not do is qualify anyone to service a regulator, a BCD inflator or a cylinder valve. Those have internal wear parts, service kits, torque figures and test procedures that belong to a trained technician working to the manufacturer schedule.
An O-ring pick is the difference between a two minute fix on the boat and a dive you do not do. Picks come in several profiles, and the O-rings themselves are sized to the fitting rather than being general purpose, so match the O-ring to the equipment rather than to whatever is loose in the box. A set with a few profiles is more use than a single tool.
Cover removal tools, support handles, adjustable spanners and Schrader valve tools are made for particular jobs and sometimes for particular manufacturers parts, so check the manufacturer specification before assuming one fits your kit. Using them on the outside of your equipment is reasonable. Using them to open a first stage or a cylinder valve is not.
SiTech combi tools and valve removal tools are made for specific valve and ring systems, so check what your suit is fitted with before ordering. The systems are not interchangeable. If a valve or seal needs replacing rather than simply removing, we repair and service drysuits here: see Drysuit Repairs.
A small tool roll that lives in the car is worth more than a full bench at home. Assorted O-rings, a pick, spare mask and fin straps, a mouthpiece and cable ties cover a large share of the things that end a day of diving. Add the tools your own setup actually takes, and if you are not sure what those are, bring the kit in and ask.
