Scuba Tanks

Annual Cylinder Test

You’re probably not going to be too happy when you want to head out for your first dive of the season and you take your tank to the dive shop for an air fill and find its out of test. No dive shop will fill a scuba cylinder out of test. Check your cylinder and ensure it is still in test before wanting to dive in this season.

Ozaquatec Scuba Service Centre is a full accredited SAI Global Hydrostatic Cylinder test station complying with Australian standards AS2030 and AS2337. See Hydrostatic Testing

Cylinder Visual Inspection

Just with doing checks on your other Scuba gear its always worthwhile to do your own external inspection of your cylinder. You should be looking for any damage such as gouges, dents or corrosion. To carry out this inspection thoroughly, the cylinder boot and mesh are removed. Check for any signs of problems and if you find some get the cylinder looked at immediately at a licensed cylinder testing station.

If you have a tank handle, make sure it’s secured properly.

Now that covers all of your main gear but don’t forget about all your accessories…
Mask and Fin straps have a great knack of snapping just at the wrong time. Be sure to check them over, stretch them to look for any tears or splits. For your own sake make sure you carry at least one spare strap of each type you use in your emergency spares box!

Batteries

Computers have had battery condition indicators for years now, but don’t forget that batteries are affected by temperature, so even though the indicator might say 50% whilst on the surface attached to your nice warm wrist, as it hits the water and cools down it could quite easily fail. Be safe, get it replaced (or do it yourself if it’s user changeable) before the battery level gets too low.

O-rings

Items such as your torch shouldn’t be overlooked either. The O-ring that is preventing it from being flooded should be checked. Carefully remove the O-ring (don’t use sharp implements as you could nick or cut the o-ring). Give the O-ring a wash in some warm soapy water and dry it. Inspect the O-ring for any damage, and finally apply and a sparing amount of silicone grease.

The groove in which the O-ring sits should also be cleaned out and dried before re-inserting the o-ring.

Our Final Note

This checklist and these steps should never replace proper servicing carried out by a trained and qualified service technician. Consider these steps as a check that everything is in good working order and a means of spotting potential problems before they become an real problem.
