I was there last year in Sept Water was almost 80 vis. between 75 and 80 ft. at peligan rock and about 60 at santa Maria less because it faces the open sea.Dove once with Amigos crew was OK but the owner was a jerk. We are trying to go in August to go to gordo banks. Two years ago it was the best Dive I ever had two whale Sharks came up to the Boat after the Dive. me and my wife slid right on the back of one and the Divemaster and bill got on the outher. we went for an e ticket ride that I will never forget. The boat Capt was really mad at us all because the two Sharks went in two Different Directions and almost lost sight of us.We saw schooling Hammerheads, tuna,Marlin,barracuda and Black Coral.Cant wait to go back. Go to the Marina to find the Dive shop there are six in the Tesoro Resort.
