I've recommended several dive shops/ dive ops in this forum. The people I have recommended here are people I use on a regular basis, not once a year, ever other year, or once upon a time! I work for none of the shops I have recommended, neither am I associated with them in any way other than on a consumer driven basis. That being said, if one is going to be diving in Key Largo or Tavernier, I recommend in this order, Blue Water Divers, Sea Dwellers, Conch Republic Divers and Divers City. These are the people I use on a monthly basis. Hope this info helps. :tree: Bob
