A Deep Blue Dive - Marathon and the Key's best source for all of your scuba, snorkel, and boating needs

We are one of the very few dive shops in the Keys that offer the excitement of this growing sport. We can instruct you and rent you the proper equipment. Put on a tank, or if you like to free dive, the Keys are a great place because of the shallow waters along with the reef line. Our instructors can teach the beginner or fine tune the seasonsed hunter. In the Keys fragile eco environment you always take ONLY what you will consume. And, we can point you to the local restaurants that will cook your catch. Grouper with Key Lime Butter, anyone?
