I did google the scuba sextant because I couldn't fathom how a sextant which works by reference to celestial bodies could work under water and it turns out it's really a Nav-finder by Padi. Now what I find interesting about it is it makes life easy for the diver because you have a form of sorts to record your dive directions on.

To use it simply requires you know your kick cycle distance and pay constant attention to your heading. Pretty slick and I appreciate the posting talking about a scuba sextant because I would have never considered a way to do it with a tool.

I've done it the hard way by making notes on a slate, pretty common but I like the automated way, well, sort of automated. Thanks for the posting, I learned something new today and now I'm happy.
