The main requirements for effective field maintenance are:

  1. Space and lots of it, to lay your disassembled equipment out so you can go over it methodically.
  2. Time mistakes happen when you are rushed.
  3. Peace and quiet: mistakes happen when you are distracted.
  4. A clean environment Beware drips of water trapped under o-rings or behind the film advance lever.
  5. Good light to see what you are doing.

The same basic principles apply to photographic equipment as you were taught about your diving equipment, only more so (Wash - Dry - Store). Photo equipment is even more susceptible to ingress of water and needs regular maintenance to ensure the integrity of pressure seals.

The increased level of salinity found in most tropical locations can eat your camera alive. Ideally you should soak your gear in fresh water as soon as you leave the water. Flushing is not enough; you should soak for half an hour minimum, overnight if possible, and operate all the controls in the rinse tank to ensure fresh water gets behind all the levers too.

Problems to avoid You should never allow cameras to dry out before freshwater soaking. Abrasive salt crystals will be left deposited on any part of your equipment allowed to dry out and this can be especially harmful to hidden o-rings the next time you operate the shaft they protect. So, keeping your housing damp, even with seawater if that is all that is immediately available, is desirable.

You can do a complete maintenance cycle after every dive but it is a much more accepted procedure to get into the habit of breaking down your camera at the end of every working day, but this is a good philosophy if limited to those parts that MUST be opened. True, if you check everything, any plugs that have worked loose for instance are automatically put right, but you also risk introducing foreign material that could potentially bridge O-ring seals.

geat advice! In extreme cases where equipment refuses to come apart, soak in a mild acidic solution such as vinegar, operate controls. Resort to force, such as stilson wrenches, only as a last resort. Most parts can be worked free with repeated manipulation.

Check o-rings for nicks etc. in good light

When you work an o-ring through your fingers to grease it, it increases in size. You may need to leave it to resume its normal shape.

Problems to avoid Think Security: If you must leave equipment unattended in hotel rooms, don't make it easy to steal, chain it. It won't deter the determined thief but it will deter the opportunist. Don't leave cameras out whilst the hotel room is being cleaned. You will end up with a layer of dust over them.
