Learn About Scuba Diving Equipment For Fun And Safety

There is much more to recreational diving than simply donning scuba diving equipment and jumping off the boat. Any underwater activities require some degree of safety training and instruction, and the use of self contained underwater breathing apparatus is no exception. Normally, humans staying underwater for long periods of time would drown. The use of scuba diving equipment has overcome that limitation. Scuba diving equipment allows the diver to take his own supply of air underwater, without the need to return to the surface often or the limitation of a breathing tube.

The pressurized air tank is the heart of the scuba diving equipment. It is a tank small enough to be strapped to the diver's back. Don't let the small size fool you. This tank contains air pressurized up to 3000 psi. That's more than 200 normal atmospheres! A tank full of atmospheric pressure air would be no better than holding your breath! That kind of high air pressure would instantly damage a diver's lungs if not properly regulated. The scuba diving equipment contains a regulator which reduces the pressure to breathable levels. The extreme pressure of the scuba diving equipment's air tank contains the equivalent of thousands of regular breaths.

The scuba diving equipment must contain a mask. Much diving is done in salt water, which can irritate the eyes. Furthermore, water acts as a lens, altering a diver's perceptions much like eyeglasses do. Including a scuba mask in the scuba diving equipment allows the diver to see clearly and effectively underwater. Not only does this enhance the underwater sightseeing tour, it allows divers to keep track of each other.

A weight belt might be needed with the scuba diving equipment. If you've ever tried to swim underwater holding a beach ball, you know how hard that is to do! The scuba air tank plus the water itself tend to increase the diver's buoyancy, forcing him to the surface. A weight belt provides the proper ballast to allow a diver to ascend or descend more easily.

Swim fins are an essential part of scuba diving equipment. Humans are not particularly effective swimmers, compared to fish. Swim fins mimic the fins of fish, providing more surface area with which to push through the water. The fins also amplify our natural swimming motions, much like a kite amplifies the power of the breeze. The air tank carries a limited supply, so having swim fins in your scuba diving equipment allows you to make the most of your diving trip to the reef.

There are many other types of scuba diving equipment. These can include depth gauges, tank capacity gauges, and even radios that allow you to converse with other divers. Before going on your diving vacation, call ahead to see what kind of scuba diving equipment is required for the dive.
