Did a dive from this shop February 18, 2012 and want to say it was one of the best experiences I've had. Everyone was very professional and friendly. I would highly recommend them if you are in Marathon Fla. More

We had an amazing time with the snorkeling trip ! the people who work there are very friendly and attentive. They want to make sure you are satisfy, and go the extra mile with all the little kids. We also rented jet sky from them, and they were awesome... definitely will go back !!! More

I thoroughly enjoyed my experience with the Deep Blue Dive Center. It was my first time snorkeling and they were patient with me and enthused to have a rookie aboard.
