Questions about this item:

Having the right stuff in your save-a-dive kit can make the difference between a great dive and the worst day of diving you ever had. You're getting your cylinder filled and pop! You blew the neck seal. Watching everyone else swimming out from the beach or making a giant stride entry off the back of the boat and you're just sitting there with a bad valve to cylinder O-Ring. This is something that can be prevented if you come prepared. Always carrying spares of the easily replaceable parts can make this nightmare never happening to you. Four Bits and the dive is saved! Have plenty of spare O-Rings on hand in your Save-A-Dive Kit.
