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 still offer the excitement of this growing sport. We can rent you the proper equipment and instruct you on its use. Put on a tank or free dive if you like. The shallow reefs of the Keys offer a wide variety of fish and a great place to hunt. Our instructors can teach the beginner or fine tune the seasoned hunter. In the Keys fragile eco environment you always take ONLY what you will consume. You can cook it yourself or we can point you to the local restaurants that will cook your catch.
