Sweet. I am really looking forward to going.
I have no intentions on getting down to 100'. I am fresh off certification, and 60' sounds good enough for me, for now that is...
The whole purpse of this trip for us is to get as much time in the water as possible to get more comfortable.
If you're fresh off certification, you may want to wait a while before heading to Ginnie. The open water part of Ginnie is about 12' deep max. In order to get to the 60', you have to go into the cavern and swim back close to 100'. My advice is to not do this without appropriate training. OW divers have died in the Ginnie Ballroom.
