"we could drop a secchi disk from the surface"

I hope I do not sound to ignorant but what is a secchi disk? Is it like in fishing where they take a white painted disk of known diameter and a string attached to it. Drop it into the water until it becomes invisible and then measure the length of line to get clarity.

I suppose a small version of that could be made suitable for carrying in a BC pocket. At any depth you could take it out drop it away from you and record the length of line. A light line with a knot tied every foot should do it or. Or possibly the buoy line could be used in some fashion. It might even be a fun activity to do during diving. Your buddy could even grab it and swim off slowly until he and it goes out of sight (tug on line), then swim back following the line to get horizontal vis.

I also wish spelling check was part of the board, but instead, for longer messages I compose them in a separate window with a tool that does have spelling check and then cut and paste in into the board message.
