I took the Scuba certification course at UDT & just finished 5/11/14. It was by far one of the best put together courses & the instructors (Evin & Josh) were very knowledgeable. I feel very safe with my newly learned scuba skills & I am extremely excited for my first "official" dive in Roatan! SSI is a great course. Do it, not PADI! I would highly recommend UDT to my family, friends & anyone wanting to get scuba certified or update their certification. Their dive shop has absolutely anything & everything, you could need or ever want for diving!!! Scuba on my friends!!!
