Artifacts recovered after long immersion in salt or freshwater require conservation treatment if they are to last. On exposure to high concentrations of oxygen in the air, iron artifacts will bloom into piles of rust. Wood will crack and split if dried out improperly. Organic materials will crumble to dust.
The manual below details conservation methods for many types of materials and artifacts.
You might not think that color matters much, but I prefer light, bright colors for any accessory that I might drop or set down. This includes knives, lights, bags, weights, and many other things. Yellow is my favorite color for this.
Despite the fact that black is really the only cool color for tech divers, I prefer Coast Guard orange uppers on my drysuits. These make you easier to spot, whether in the murk of the quarry, or drifting away on the surface of the Atlantic.
All equipment must be black. Ha ha - just kidding. You guys can take a joke, right?
