Diving Bcd
What constitutes the minimum equipment that recreational divers should have and use on every dive? To some extent this will be an environmental factor and the effects immersion. Divers in cold water require more thermal protection than divers in warm water. Divers engaged in activities such as photography or night diving, deep, wreck, or ice cavern diving, require additional specialized diving equipment that sightseeing divers in shallow waters, Open water is not needed.
There are, however, some equipment items that most experts believe recreational divers should have and use on every dive. The following is a brief description of each of these elements.
Mask, snorkel and fins
These are the most basic of all diving equipment. Masks allow divers to see underwater without distortion. Tubes on the surface to breathe without having to raise his head in the water or air using their tanks. Fins allow divers to move through the water with great efficiency of the measure.
Exposure Protection
Divers need protection from both heat loss and abrasion. The heat loss is of particular importance because water conducts body heat 20 to 25 times faster than air of the same temperature. Divers may become dangerously cold water seems too hot, if it were air.
Thermal and abrasion protection suits can range from mild neoprene diving in temperate waters thick, highly insulating dry suits for cold water diving. Most divers also use some form of hand and foot protection. Wet suit boots are the most common form of foot protection. Hand protection can vary from thick wetsuit gloves or light gloves.
Weight Systems
Depending on the natural buoyancy of a diver and dynamic team, you may need to use some kind of system weight to offset the excess buoyancy. The most common type of weight is a weight belt, but the general options available.
Diving Systems
Modern diving systems integrate several components, including sources of primary and alternate air, the buoyancy control device (BCD) and instrumentation.
Sources of air
Source of a diver's primary air comprises a compressed air cylinder and a two-stage regulator reduces the air at the same pressure the surrounding water. The most common form of alternate air source is an additional second stage regulator, similar to the diver breathes normally. This extra phase II is shared with other divers to be depleted, or out of breath.
Devices buoyancy control
A diver's buoyancy control device (or BCD) is used for two purposes. When inflated in the area, allows the diver to rest or swim comfortably without having to fight to keep his head above water. Underwater, the BCD may be partially inflated to compensate for any reduction in buoyancy caused by compression of the exposure suit diver during descent.
Meters
The minimum instrumentation with which each diver must be equipped with include:
a means of controlling air supply
an appropriate way to determine the depth
a way to measure the time spent under water
Also recommend that each diver have and use a compass underwater. This not only makes it easier for the diver to navigate, but also helps to eliminate the need for long, exhausting all surface at the end of a immersion.
Knife or tool
Although the risk of becoming entangled under water is scarce, it is recommended that all divers equip themselves with some kind of cutting tool. Depending on its design, this tool can also be used for the curious and measurement.
Record Book
Because the cards certification only provide that in a moment in time, a diver met the minimum requirements for certification at this level, divers record their dives in the record books. Log books provide a tangible record of the depth and breadth of experience of divers. A growing number of stations and dive operations charter require that present both divers certification card and log book before they provide a service for diving.
Slate
The ability to communicate underwater with hand signals is limited. Therefore, to transmit more complex messages to each other, divers use specially designed boards underwater.
Using slates can eliminate the need to discuss surface and can add comfort and enjoyment of the dive.
