PRE-DIVE EQUIPMENT CHECKS

Scuba diving is very equipment intensive. The equipment that you take into the water with you is not only your life support equipment, it is also your buddy/teammates emergency life support equipment. If you haven't gone diving in more than a year, it's a wise idea to have all your equipment serviced before taking the plunge. There are lots of rubber seals inside scuba equipment and they eventually go bad. Equipment can seem to work on the surface, but the moment you hit the water, things can start to leak. So it's a wise idea to have it examined if you've been out of the water for a while. Remember to have all your equipment inspected and serviced before every season.

Pre-dive checks are a critical part of diving and a proper pre-dive equipment check should always be performed, even if all you did was switch tanks between dives. Using a pre-dive checklist every time will help unsure that you don’t miss or overlook anything. Just like pilots do, it’s a good idea to use a printed checklist to make sure you check everything. Generally speaking, the one item you fail to check will be the one item that fails. You can go through the pre-dive checklist before you suit up, this way if there are any problems, you can deal with them early on, instead of having to undress.

Below is an example of a pre-dive checklist. You may use it as-is, modify it to meet your needs, or create a new one that works better for you.

Check the tank and tank valve for any obvious issues. If it is a yoke style valve, check the O-ring on the face of the valve.

Wet the BC or BP/W straps that hold the tank, and then attach to tank.

Put regulator(s) on tank and hook up low pressure inflator.

Hold the pressure gauge in a safe direction, slowly turn on the tank valve all the way and listen for leaks. Check the pressure gauge (SPG).

Purge to blow debris out of the second stage regulators, check for odor, than breathe from the regulators.

Inflate BC/wing with the power inflator until you hear the pressure relief valve activate.

Check all BC/wing dump valves to insure they work and seal.

Turn off the tank valve and breathe down excess gas until there is nothing to breath. Try breathing from each second stage regulator. This is called a negative pressure test. If you can breathe from them, there is a leak and your regulators should be inspected and serviced.

Hold the pressure gauge in a safe direction, turn on the tank all the way and listen for leaks. Breathe from your regulator while watching the pressure gauge (SPG). The needle should not move.

Check your buckles, weight pouches, fins and mask straps.

Make sure your buddy does the same procedure with their equipment, and then check each other’s equipment the same way. Once your scuba equipment is setup, you can don suits, weight belts and go dive.
