Underwater Camera Maintenance Checklist: Pre-Dive and Post-Dive Care
A single skipped check at 60 feet cost Marcus Okafor $2,800 when seawater flooded his camera housing. In this episode, he walks through the exact pre-dive and post-dive maintenance routines that protect your underwater photography gear from leaks, corrosion, and costly failures. Whether you shoot with a simple point-and-shoot or a full mirrorless setup with strobes, these step-by-step habits apply to every system. If you've ever wondered what separates photographers who consistently bring home sharp images from those nursing flooded gear, this checklist is your answer.
Key Takeaways
- O-ring inspection is your first line of defense against floods. The rubber ring that seals your housing is like the gasket on a jar lid—one tiny grain of sand or a single hair can create a gap where water sneaks through. Check it under good light before every dive and clean it with your fingers, not towels that leave fuzz behind.
- A bucket test catches leaks before the ocean does. Submerging your empty, sealed housing in fresh water for a few minutes lets you spot air bubbles that signal a problem. Think of it like checking for holes in a bike tire before a long ride—much easier to fix on land than underwater.
- Pressing buttons underwater during your rinse flushes out hidden salt. Salt water hides inside the tiny gaps around your controls, and when it dries, it leaves crystals that jam everything up. Working each button while soaking the housing pushes that salt out before it can cause damage.
- Desiccant packs prevent fog from ruining your shots. These little silica gel packets absorb moisture inside your housing like the packets you find in new shoe boxes. When they change from blue to pink, they're full and need replacing—otherwise your lens fogs up and every image comes out hazy.
- Post-dive soaking is non-negotiable for gear longevity. Spraying your housing with a hose isn't enough—a proper five-minute soak in fresh water dissolves salt before it corrodes metal parts and freezes controls. Skipping this step is how expensive gear ends up in the repair shop.
