Dove Hole in the wall twice this week and both times it was great. Both times I went up stream but in that tunnel the visibility was at least 50-60 feet which is enough to see the largest of the rooms from wall to wall and ceiling to floor. It doesn't hurt that I got a great deal for the guys at Cave Adventurers on an Underwater Light Dude 35 Watt light. The light was bright enough to light up the largest of the rooms in Hole in the wall. There was a little bit of flow but both dives we made it past the line to century tunnel and made it about 400-500 more feet in with back gas diving HP100's. At the top of Albert's Room the water got significantly colder but also clearer. All in all great dives.
