I've done a few dives where vis was basically 0-5 ft. You need to get out to Indian Arm for the truly awful vis. I did a couple of crabbing dives this summer where my buddy and I kept tabs on each other by literally swimming so close that we were always bumping into each other. Porteau can get pretty skunky in the fall, too. I remember assisting with one AOW dive out by the Granthall in particular: upon descent, I could see that the vis was really tenuous, sort of a halocline haze all around. As soon as the students touched down - BOOM! Vis was totally gone and I basically got myself and the other students to sit tight until the instructor thumbed the dive. Rory basically had to thumb the dive by putting his hand about 6" from my face, and we were sweating about getting all the students back up!
