I made a wrist slate with a compass and BT from a piece of 6" PVC. I cut a
hole in it for the Icolite compass to push up from the bottom. This way only
the face of the compass is sticking up reducing the overall profile. It also
has a Hyper Aquland watch strapped to it and a small pencil with surgical
tubing holding it in place. I have been able to write on the slate with
mittens. Normally I only write deco, heading or any other 
project related info on the slate prior to the dive. I have found that if I
need to ditch my gear I can pull off the slate fast enough to prevent it
from catching a strap.
Also I only use this in ocean diving. Don't do the cave thing...

I would be glad to take a picture and send it. Let me know....

Moriarity Sr.

I've been playing with the idea of a cut in 1/2 piece of  3" PVC, with the
compass, BT and watch mounted on it, on my left wrist (rather then have all
three separate).  I've seen a few, and none have really fit exactly what I
wanted in the layout.  I have to get a piece of 3", and take the heat gun to
it to make it conform to my arm better then the standard size/bend.  I've
seen a few arm slates, but don't have a source as far as manufacturer, so I
haven't explored that route.  All I do are ocean dives, so I also use the
compass on every dive, having them all separate is kind of a pain in the
ass.
