I copied this from my post on another string and modified it for dates:
I returned from T&C about two weeks ago. Sorry for the late report. I did four (technically five) dives in two days with Dive Provo. First dive was a washout. There were four divers and two dive masters (one being the boat captain). We tried to go in front of Grace Bay. Visibility was about ten feet at best. The dive master hoped it would be better by the wall, but called the dive after about eight minutes. We went up and then went to the north end (?), in front of Amanyara. Viz was great - 100'. We did a full dive there. I was impressed with the fish life, shark, and corals. It was a wonderful dive.
We slowly moved to our second location during our surface interval. It was a short ride to the Black Coral Forest. Viz there was slightly worse at about 75 - 80'. Still a great dive.
The next day had a lot more divers - about 11 divers with two snorkelers. Five of us were "singles". We went to West Caicos. Both dives had about 60 - 70' of visibility. More great life and coral and some very curious sharks. I've never had sharks just hang around - almost circling. The only thing I didn't like about the dive was one of the divers. He was a novice diver and constantly doing the breast stroke while diving. I did my best to stay away from him and not get my regulator ripped out of my mouth. Luckily, he didn't hurt the other novice (female) diver he was hitting on above the water. The last diver came up about ten minutes after me and said the viz was deteriorating quickly as he finished his dive. I'm not sure what was affecting the visibility because it was less choppy than the day before.
