Underwater photographic equipment requires special care and maintenance. Your equipment has been designed to be submerged. It has been constructed to seal against water; that means it is watertight. The internal electronic mechanisms that drive the system are protected only if you protect the components that keep the water out.
Your system is vulnerable to a host of natural enemies. Here are the things that can harm your equipment:
A maintenance regimen is essential. You've made a considerable investment in your equipment. Treat it properly and it will perform for you for a very long time. Neglect it and it will need costly repairs or, even worse, replacement.
The first thing you do after a dive is rinse your system in fresh water. Salt is your system's number one enemy. Salt water can dry and form crystals within 10 minutes after you surface. Submerge the system and let it soak for at least 30 minutes. While the system is soaking, agitate gently and work all the controls at least once. This will help flush out any salt residue.
Do not rinse your system with a hose. The high pressure may actually force salt crystals and sand into crevices. Lay the system on a clean towel and let it air dry; this allows water in inaccessible areas to evaporate. Then, using a clean, dry cloth, wipe excess moisture from the body, ports, levers, connectors, and so on. Do not wipe the lenses. Only lens tissues or photographic lens cloths should be used on lenses.
O-rings are the most important components of your underwater camera system. If the O-ring is lubricated, it will be elastic enough to shape itself uniformly around the channel. If it is dry, there will be too much friction to allow it to reshape itself uniformly. It will not safeguard against flooding.
Every time you open the camera to change film, examine the O-ring and service if necessary.
ALWAYS (ADVICE OF ESKO Diveworld)
NEVER (Advice of ESKO Diveworld)
|Before using your equipment, carefully inspect all the O-rings for salt, dust, sand, hair, cracks, nicks and any debris or damage. If an O-ring is dirty, clean it. If it is damaged, replace it with a new one.|
Never use a sharp or pointed object to remove an O-ring from its channel. Never pull, twist, stretch or bend an O-ring. Abusive handling can damage the O-ring and void its sealing integrity.
|To lubricate an O-ring, apply a dab of silicone grease to your fingertip, then draw the O-ring through your fingers till it is evenly coated. Use the grease sparingly. Too much grease attracts dust and debris.|
Always open the back door on your camera with the lid facing down. In this position any trapped water will fall out and away from the interior. Open all O-ring-sealed equipment in this position.
