I did my PADI Advanced Certification with Pat at Silent World Dive Center in Key Largo last year. She was great! I was the only one doing a class and had lots of one on one time to get all my questions answered. We dove the Spiegel Grove, the Benwood, and a few sites on Elbow Reef. It was a blast! Chris helped me get my BP/W set up and adjusted properly in the AM before we went out, and talked to me about equipment choices and answered some of my questions about DIR. Their boats were comfortable, and only had 8 divers on each. I would not hesitate to dive with them again. Hope this helps.
