Pocna deserves no less than 5 stars. This was my first scuba diving experience so I chose the discovery dive course.The staff here is very skilled, didactic, passionate and fun. I was started off with a 20 minute video describing the experience, instructions, safety features and physiological effects of pressure on the body. This was followed by breathing and mouthpiece practice in shallow water prior to a 30min boat ride to open water. Diving isn't trivial and they were patient and sensitive to everyone's questions and occasional distress. We dived twice for about 30 min each time. First in the MUSA museum. The sculptures were breathtaking and included a miniature house, a Volkswagen Beetle and a haunting collection of human statues frozen in time. Second was to a nearby reef called Manchones. It was another shallow dive (approx 8m), during which we swam along with an incredible array of fish including stingrays, blowfish, lion fish, a huge puffer and many more. Special thanks to Hannah and Lalo for your competence, patience and for making this experience a day we'll never forget.
