Scuba diving is a lifelong hobby for many. If you are interested in it as well, then buying your own gear will probably be a good long term investment. In the beginning, you will be overwhelmed with all the items you need to purchase, but stick with it and it will all become second nature to you. To some degree, this will be a factor of the environment and the purpose of the dive. Divers in cold water require more thermal protection than divers in warm water. Before you go for shopping, you need a list of all the essentials you are going to need. Dive Slate: The ability to communicate under water using hand signals is limited. So, to convey more-complex messages to one another, divers use specially designed underwater Dive Slate. Buoyancy compensators: Buoyancy compensators are one of the most important pieces of equipment you can get, so starting here is a good idea. Buoyancy compensators are also known as a stab jacket and are a piece of scuba gear that's worn like a jacket and holds a bladder which establishes neutral buoyancy underwater. Dive Gauges: The next item on your shopping list should be Dive Gauge. Dive gauges come in a variety of different styles; you have compasses, analog and metric analog. They are used to show you the PSI and depth. They are your basic navigational equipment when under water which is why many come with a compass as well; your dive gauge should always be included in your scuba gear. Exposure Protection: Divers require protection from both heat loss and abrasion. Heat loss is of particular importance, because water conducts heat away from the body many times faster than the air. Divers may become dangerously chilled in water that would seem uncomfortably warm, if it were air. Thermal and abrasion protection may range from lightweight wet suits for warm-water diving to thick, highly insulative dry suits for cold water diving.
