The recent thread in the sidemount forum sparked my interest in this seemingly "overused" type of training. So, I posted a poll to see how many CDF Cave certified divers were trained in the time periods listed. Please assist me in my personal venture into this currently unknown information.

The poll is posted as "private", meaning no one will know which option you choose, so be as honest as possible and know that you cannot be ridiculed for your selection.

Thanks.
