Did you know that most people only see about 25 percent of the world? The reason is that they don't know how to scuba dive. Scuba diving is an activity that can be very beneficial in allowing a person to see the 75 percent of the world that is underwater. It is also a great way to exercise.

We were invited to go to Long Island Scuba, and take a Discover Scuba class. In the class, we watched an introductory video about scuba diving safety. Then we were given in-water instruction in a heated indoor pool. Our instructor, Dave Keller, provided us with instruction on how to use diving equipment so we could safely breathe and swim under water. The main equipment that allows you to breathe underwater is an air tank and a regulator that you put in your mouth. The equipment that allows you to move underwater is a vest and flippers. The vest can have air added or taken away to adjust how buoyant you are.

We were nervous! On our first swim around we were shaking. However, our instructor was encouraging and patient, and he helped us overcome our fear. After about a half-hour of hands-on practice with the equipment, we were swimming underwater for 10 to 15 minutes at a time. We felt very confident. Swimming under water and practicing picking up objects was both calming and exciting.

The owner of L.I. Scuba, Ralph Collis, along with our instructor Dave, shared with us many stories about their best experiences under water. Dave said they even once found gold. They told us that scuba diving in Long Island waters is more difficult that most other places. If you can scuba dive here, you will be prepared to scuba dive anywhere.

We had a great time here. We think that it is a great activity for kids 10 and older. We would recommend Long Island Scuba as a great place to begin your underwater adventure. In addition to instruction, they have a full line of equipment for sale and can also repair equipment. They also have a tank refill station if you buy your own air tank. It is located at 895 Wellwood Ave., Lindenhurst. Call 631-225-8450, or on the web: longislandscuba.com
