I only realised when it was a bit late and as it happens I wanted to give it a go. Even with a less than 30 minutes surface interval - would have liked more but we seemed to be picking up divers and time was pressed. And it should be noted that its hard to get deep dives here in Antigua anyway. I had lots of non deco left..
We saw 2 nurse sharks in close proximity on the dive and much much more besides. Catherine has made a really good video which shows how good diving in Antigua can be.
