The equipment needed for diving is divided into light equipment (fins, mask and snorkel or snorkel) and self-contained (bottle, buoyancy compensator, regulator with gauge and pressure gauge, and ballast). Additionally, the scuba diving equipment usually includes a dive computer a marker buoy, a flashlight, and a small knife, and depending on the temperature and currents, a hat and gloves (snorkeling grace bay beach).
While for all recreational diving certification emphasize that the most important rule is to never dive alone, there is discussion about it in 2001 Drew Richardson, a senior member of PADI, spoke favorably solitaire diving, recognizing that this can be accepted for suitably qualified divers and experience necessary.
It is the simplest form and oldest diving method employed by man, and appears in various regions and cultures to exploit food sources (fish, crustaceans and molluscs), useful resources (algae, sponges, corals) and resources of cultural value or economic (beads). The scuba diver using a compressed air bottle that lets you go breathing the stored air, giving it considerable autonomy (usually around an hour).
However, current safety standards require a number of tools that let you know how deep you are and what air pressure is left, called depth gauge and pressure gauge, respectively. Dive computers are also becoming popular, depending on depth, mixture of air and the time spent underwater, they indicate at all times the depth range where you can stay.
Notwithstanding the limited mobility diving diver because he stays connected to surface by an air hose. Scuba diving is one that does not require any connection to surface. The quest for autonomy by inventors occurred during the nineteenth century some inventions of limited effectiveness, the most notable of them being the regulator mentioned in Jules Verne's novel Twenty Thousand leagues Under the Sea.
The role of wetsuits is to protect the diver from hypothermia. The thermal insulation of skin is not adapted to aquatic environments because the specific heat of water is higher than the air. In water below 27 degrees Celsius, it is recommended to be thermally insulated; temperatures below 22 degrees Celsius and with 15 degrees Celsius or less good insulation is essential.
There are three basic types of isolation suits: wet suits, dry suits and semi-dry suits. The first generally are suits made of sparkling and resistant materials (usually neoprene), which form an insulating layer between the medium and the skin, but not waterproof. Its efficiency depends on the thickness of the foam and the body fit. Wet suits can be short or long, depending on the number of parts are classified into one-piece or two-piece suits.
Dry suits can be of two types: neoprene trilaminates. They reinforced sealing cuffs, ankles, neck and a special zipper that prevent entry of water between the suit and the skin, are more effective than wet, keeping the body out of contact with water, greatly limiting the loss of temperature. An extra complication is that the air inside the suit is under compression, so their compensation must be worked on during the dive as it is done with the air of BCD, for this has valves filling and exhaustion and courses are taught.
