A single skipped check at the surface can mean a flooded housing at depth—and a repair bill in the thousands. This episode walks through the complete pre-dive and post-dive maintenance routine that separates photographers who consistently bring home sharp images from those salvaging waterlogged gear. Whether you're shooting with a compact setup or a full mirrorless rig with strobes, these step-by-step habits protect your investment and keep your housing watertight dive after dive. If you've ever wondered exactly what to inspect before splashing or how to properly rinse your gear afterward, this breakdown covers it all.
