I think you would, simply because they are not commercially available, and the novelty factor alone is strong enough to attract at least 2 other buyers.

Generally the bigger the compass the more precise it is. Compasses being liquid filled should be able to go DEEP. rzep is right on the mark. I still use a console and one of the reasons is the ease of compass use it provides. I haven't used a wrist compass diving since the early 1980's they are a PITA.

IF you are looking for something to get back to the boat look at the Desert Star System stuff.

I am designing my own board with a Ritchie Kayaker compass . Basically it's the same compass as the TAC 200 but has no open face and is not luminiscent.
According to Steve from Ritchie:

The Ritchie compasses have been used by Benthos to 1 ½ miles beneath the surface. The liquid filled compass with a diaphragm is neutral and doesn’t have pressure problems.

The kayaker does have the same footprint as the TAC-200-2 but the dial is not open face or luminescent.

So i will add a chemlight for soft illumination during night use. The kayaker compass is removable from it's holder so you can safely transport the board without the fear of damaging the compass.

I'll post pictures when done.
