Amazing dive... entered a zen state. Did the cave again, then came straight back through to return the the shark gutter on the deep end (the shallow cave entry was getting slammed, so not much life there). Sat at the bottom of the shark gutter and just took the most amazing photos... and went into deco by a few minutes because I was so entranced. Whoops. Ascended really slowly and spent 10 minutes at 5m to be sure. I was great on my air too - surfaced with 50 bar starting from 200, which is an impressive effort for a deep dive like this.
