Keep in mind that a lot of "farming out" goes on on AC. This is where the smaller shops work together when they don't have enough divers for a particular dive (ie. night dives or Blue Hole/Turneffe). They set you up with another shop which has enough divers and equipment for that dive. This enables the samller shops to compete with the largest one. And unless you set up with the largest dive operator, Amigos Del Mar this can and will happen. Amigos told me they never "farm people out" to other dive shops. I don't think any of the other dive shops can say that.
In searching for a dive operator it is necessary to ask people who have dived with more than one dive shop - so they have something to compare one from another. Otherwise all you get is people who have "pet" shops that they use and no other shop to compare theirs to.
That being said - I dived with Hustler and Amigos Del Mar.
While Hustler did not have their large boats available for long trips such as the Blue Hole, they did a great job on the local diving just off shore. Everitt, our divemaster was excellent. He took my wife by the hand and made her dive very enjoyable by showing her things she would never have seen otherwise. For the long trips right now they "farm people out" to Aqua Divers. That sometimes does not work well as our freind Eracsder found out when Aqua Divers called him at 10PM to tell him his trip was off. Needless to say he was PISSED OFF, both with Hustler and Aqua Divers - and you know I can't blame him for being pissed. When Hustler offered to set up my Blue Hole dive I graciously declined and went to Amigos and Eracsder joined me.
Amigos Del Mar - There's a reason that so many people praise their work. They are the best on the island - most proffessional, well equipped, with the largest boat and largest group of divemasters on the island. They do not take saftey for granted and they make you feel that your safety is their #1 concern.
In doing the Blue Hole and Turneffe with them, I was completely at ease and when the diving was done they had lots of refreshments for us, to make the trip back to AC more enjoyable. They had candy bars and snacks, pop, water, beer, and rum punch (panty rippers).
There is usually one dive shop that stands head and shoulders above the rest. Here on AC it is Amigos.
What more can I say?
