Regulator
Modern scuba diving (scuba diving) can be said is based on the breathing regulator (regulator) of the invention. Breathing regulator (in English usually referred to as reg.) Have a different design and construction, its main function is to be within the high-pressure cylinder into the air fit to breathe the air pressure, so that we can easily breathe. Reg is basically divided into two parts, called a head (first stage) and two heads (second stage). a connection to the cylinder head, high-pressure air inside the cylinder to fit to breathe the air pressure. and then through the gas hose from the air sent to the first two divers with the two heads can be used in the mouth mouth breathing (breathing air from the cylinder output, expiratory air discharged from the first two). breathing regulator generally also includes access to a low-voltage BCD refilling hose, pressure instrument connected to the device and back-up devices such as gas source.
BCD
Buoyancy compensation vest (commonly referred to as BCD, Bouyancy Compensation Device). In the past (and even now is still very common) BCD is Bouyancy Control Device (buoyancy control vest), but the more recent years it renamed the "buoyancy compensation vest" (Bouyancy Compensation Device, or BC - Buoyancy Compensator), which is a better interpretation, because strictly speaking, is a dive BCD "compensation" buoyancy rather than "control" buoyancy. BCD is designed to be air into the vest inside (or from the release the air inside the vest), thereby changing the buoyancy. there are two ways to join the air, first by the low-pressure gas cylinders connected to the refilling hose (low pressure inflator), the other is the use of artificial blowing (oral inflation). and put air spaces (air releases) generally have two or three, mainly the upper and lower corner, could be more easily facilitate the dive in the air released from the BCD. while the BCD is also equipped with the stability and load on the back of the cylinder device. part of the new Design BCD, also includes built-in weight (integrated weight), according to standard deflated, reserve gas source and so on.
The primary entry to the BCD 2000 yuan in general Sengo about three thousand dollars or so pretty good and should be more convenient to include more features.
WetSuit
Wetsuit diving primary role is to keep warm, so there are different thickness and long sleeve styles, with different diving environments. Usually by the thinnest of about 0.5mm to 10mm thick. In tropical or sub-tropical diving, the more commonly used for the 1-3mm. during the cooler water temperatures have to 5mm thick or more
Wetsuit diving. dive in colder water temperatures may have to consider the use of diving clothes (dry suit), but pay attention to clothes is to use diving There are different skills, so it must be subject to special courses.
General
Wetsuit diving thin and cheap 3 also has several hundred dollars, such as the commonly used 2-3mm thick
Wetsuit diving, one yuan each should have a lot of choice.
Air Cylinder, Tank
Cylinders (air cylinder, but more commonly referred to as tank) is used for storing high-pressure air. Materials are mostly stainless steel or aluminum, there are different size and with a switching system and a breathing regulator connection. In addition to the individual fractional area , the majority of the number of divers who have owned gas cylinders, mostly from the dive shop is responsible for providing gas cylinders and pneumatic service. Gas prices starting from one yuan each, depending on the material, size and specifications.
