Cave diving is dangerous and MUST NOT be attempted unless you have formal cave diving training from a reconized agency. IANTD, NSS-CDS, NACD and GUE (among others) offer formal cave diving training.
Even with training, you can be killed cave diving.
For more information see the NSS-CDS's Saftey Broshure.
I took my Technical Cave Diver training from Sept 3rd through 10th with (the) Gary Taylor and I was able to carry my camera on 2 of the dives.
We entered at Orange Grove sink and proceeded to the Challenge/Distance split (~900').
Normally a siphon, Peacock III was actually springing while we were there.
