Tks Alex... I thought that was the case and I have tried it before, but from the kite. This means the image is too far out for any detail.
Another way of course is to do like you and get a linemount for the Pentax but for that there is the GoPro, the image is much better.
Tks for finding information for us.

I like the W90. Attached are a couple of snaps from Denmark WA.
The green reef looks brilliant......so do the the babes on the beach.
