I will be on the big island for just a few days around Easter and I'm trying to decide between Jack's and Big Island Divers. I am limited to these two because they seem to be the only shops open Easter night for the manta dive, which I want to do, and I don't want to switch operators during my limited days on the island. I have a large camera, I'm good on air, and I don't enjoy the cattle call operations. I don't need a baby sitter, but I also know that the dive guides know the sites better than anyone else and I appreciate it when they point out the good stuff. Anyone have a vote?
