This has to be one of, if not THE best dive outfitters in the entire Keys. First, they keep the group of divers small; there's nothing worse than a large group of spazzy unskilled divers. Second, the dive guides are all great divers with great personalities; I often have doubts about the guide's competency with other outfitters, but NOT SO with Lost Reef! Third, they take you to interesting dive sites; it's one thing just to go diving, but it's more important to see interesting stuff under there! Fourth, for those needing to rent gear, Lost Reef has good quality equipment to borrow. Fifth, they keep to the given time schedule; I hate places that either start or end later than planned. Sixth, the price is very fair for what you get! I highly recommend these guys.
