- o-rings for your tank valves and regs, and anything else that uses them
- wire ties, large and small, lots of 'em
- spare straps & buckles for mask, fins, snorkel, and knife
- spare regulator mouthpiece & wire tie

- duct tape ( squeeze a small roll flat to save space )
- silicone grease or O2 lube
- extra batteries and bulbs for all your lights, computers, and camera
- spare lanyards and brass snaps
- stainless steel dive tool with wrenches, allens, and screw drivers ( pictured above )
- stainless steel folding multi-tool with pliers, blades, and wire cutter
- glues and sealants - neoprene cement, AquaSeal, Crazy Glue
- bicycle tire patch kit - for small suit repairs
- soap, powder and wax for drysuit if necessary
