Oh come on. That isolated event above was years ago.
I've dived with LTD, Wall to Wall, DNS, Neptune, Ocean Frontiers, Sunset Divers, and all are very good operators who provide valet services.
LTD has big boats and relatively small groups. I prefer DNS because I like the group of regulars who are usually on the boat, and I like Dusty Norman, but would have no trouble diving with LTD in a pinch. In fact, Gary, who owns LTD, worked at Wall to Wall for years. If he was not an excellent DM, Giles would not have kept him on for so long.
Everyone has their favorites, but apart from a few cattle boat companies, all GC dive operations provide good service, dive the same sites with more or less comparable profiles. . They have to to stay in business in a very competitive market.
