PADI Master SCUBA Diver

What will you do with SCUBA?

This is a great dive shop to make your home scuba shop! They go above and beyond our experiences at other shops. They spend plenty of time making sure you have the proper gear for your needs, the information and instruction on classes and great trips. We tripled the amount of diving we do because of these guys!
