What goes in a save-a-dive kit?

O-ring assortment with picks, spare mask strap and fin strap, mouthpiece and zip ties, silicone grease, multi-tool with hex keys sized to your gear, spare batteries for lights and transmitters, and a DIN/yoke adapter if you cross fitting borders. Add a snorkel keeper and bolt snap. Total spend is under $60 and it converts dock-side failures into five-minute fixes — the checklist version lives in our free downloads.
