My Son and I had an amazing experience on the try dive half day course. I had a couple of dives before, for my Son it was his first. I have never had such a thorough explanation about the basics of diving. Our guide Nelly takes her job very seriously, she took great care us, especially my Son who had Some problems with his ears. I highly recommend this diving scool.
