You don’t have a save a dive kit? How many times have you been on a dive boat and someone lost a fin strap or something is missing or wrong with their gear and magically someone on the boat has that part in their save a dive kit? All it takes is one time and you are the hero of the day.
So what is in my save a dive kit?
O-rings of various sizes and more than 1 of each and at least 5 or 6 tank o-rings and a pick to remove said o-ring
Zip ties for mouth pieces and mouth pieces
A couple mask straps
A fin strap and buckle or 2
Aqua Seal for any patching of a wetsuit I may need to do
Batteries for my computer and camera
I know, that is a lot and yes, the dive boat/shop will probably have all of that stuff so why have a save a dive kit? There are times that we are not diving with a boat crew or near the shop, especially on the Island of Bonaire where shore diving is the norm. By having all this extra stuff I don’t have to drag everything back to the shop to get a new o-ring for the tank.
Most of this stuff stays in the room or the dive locker, but it has come handy on a few trips when someone needed to change out a hose or maybe they wanted to try a different hose configuration on their regulator set up.
What is not in my save a dive kit, hoses and parts for my regulators and the tools to overhaul a regulator that is something that should be done before you get to the islands.
