Sadly, there are too few participants in this forum to make it useful. I received many useful posts regarding the same question on ScubaBoard. I would question the ongoing utility of the Undercurrent Forum in its current form. Increased participation and a larger number of members might help considerably.
I just spotted the message that the Diver's Forum will be moving to the public site in the future. I hope this results in a critical mass of active participants but worry about the quality of some posts vis a vis ScubaBoard.
Good diving, Craig
