Best way to attach a grey card

[OTF]

What courses do i need to take to earn a grey card?

How about white or grey duct tape on top of your fin? If you are shooting in raw and setting WB in post, all you need is a big enough piece to get the eye dropper on.

You can do a white balance on you buddy”s tank if galvanized.

Have you tried using someone's tank? I use someone's tank so I don't have to carry a card

The idea with the tank is very good, but my upcoming trip is to the Maldives and everybody dives with yellow-green nitrox tanks there.

I am wondering if anyone has compared custom white balance using the palm vs. a grey card. Are the differences big?

I’m a diver that takes pictures not a photographer who dives

This might be a false dichotomy. There are also divers who are photographers.

You are stretching. When Jill Heinerth is doing some cave photography, for example, are you suggesting she is not diving 100% of the time?

I have no idea who that is but is the focus focus or is it diving?

Look her up.
If you are in a cave, your focus better be diving.
