I've used various and sundry things. Paint pens, sharpies, and other writing implements were my first round.
My fins are decorated with four different bright "neon" colors of small zip ties: orange and green on one fin, pink and blue on the other. If it's a leisurely, uncrowded boat with a bunch of students doing a checkout, it's ever so fun to suddenly realize you have your fins on the wrong feet and have to change them. :biggrin: The bright zip ties contrast well with the plain black fins, making fin-based ID underwater somewhat easier.
As far as gear/diver association on a boat goes, that part's *trivially* easy. I've always been the only one with a stainless steel plate, a DSS Torus wing, and an extra D-ring on a basic harness... oh, and the harness webbing is bright pink. I'm enough of a ham to enjoy standing out, and it helps keep my group together on large boat checkout trips (you can see the webbing practically *glowing* through the murk).
To complete the whole tagging thing, I can also attach laminated tags to anything that could use one. (I had to buy a laminator to use on the great [thread=212110]ISOSAD Monopoly Challenge[/thread] project -- anybody know much about small-scale metal casting to give me tips on the houses/hotels? ) Laminated tags are great for large objects (bags, BCs, etc), but they'd get in the way too much on the smaller stuff.
