Scuba diving is a sport and profession that takes place in a hostile environment for humans --- the ocean. Because of the inherent danger, specialized equipment is required which can be rented, purchased, or a combination of the two depending on how often you plan on diving. Using gear, such as the diving mask, is quite easy to learn while others require specialized training to become proficient.
Scuba Mask
The most common scuba masks offer three or four panes for vision --- the one you choose will depend on your comfort-level with one or the other. Another factor to consider when selecting your mask is the seal -- the mask's skirt or gasket's ability to form to the contours of your face, keeping water from entering the mask. The nose pocket is important for not only your comfort, but also performance, keeping the mask from fogging during a dive. Masks stay in place by a single or a double strap. Select the type offering you the most comfort.
Scuba Fins
Scuba fins make diving possible --- propelling a diver through water expending little energy while reaching velocities not possible without them, According to Scuba Guide's website. Scuba fins need to fit as your street shoes do. Some divers put on booties before their fins, giving a snug fit. Although there are many fin designs available, most common is a split or solid fin. The split fin is a newer design and cost more, however gives you better propulsion than traditional solid fin designs.
Scuba Suits
The four types of scuba suits are selected based on water temperature, dive dangers such as sunken ships, sea-life, water temperature and personal comfort. For recreational dives in shallow, warm waters, a swimsuit will suffice. A body-skin offers slightly more protection than a swimsuit, used in similar diving conditions. A wetsuit is the most common scuba diving attire, made from neoprene and varying in thickness for buoyancy and warmth. A dry suit is for cold waters, allowing the diver to wear thermal layers underneath the suit itself.
Scuba Tank And Regulator
The scuba tank may is the most important piece of diving gear, as without air diving is not possible. The tank separates scuba diving from snorkeling. The diver uses a valve to control airflow by turning a small wheel left or right. According to PADI, an organization that certifies divers, you carry the largest tanks possible. The regulator adjusts the pressure of air coming from the tank --- making it suitable for breathing by the diver. The regulator makes sure air is available when the diver inhales, and redirects your exhale into the water.
