With a BCD(Buoyancy Compensator Device), divers can move easily underwater and in a more comfortable way. The scuba diving buoyancy compensator device is a very vital device for the divers and you will greatly enjoy its benefits as you are using it underwater. Like any other device, this one has some parts and accessories, which are connected to it, in order to enhance its functioning. You can find some bcd spare parts that will be available whenever you have issues with your device. Here are some of the common bcd parts and accessories that can be easily replaced, such as stainless steel backplate, Aluminum backplate, plastic backplate; scuba bcd inflator, over pressure relief valve, dump valve, single tank adaptor, fish tail, butt plates, stainless steel wasit cam buckle, hose protector, snorkel vest, signal tube, signal tube oral inflator, lift bag etc.

Backplate in AL, SS and Plastic
A backplate is usually a solid piece that is hard and placed on the back of the device next to the tank. The backplates are usually designed with some specifications like some may have bends at the base, which helps to offer an ergonomic curve that makes the diver feel more comfortable. Technically, the backplate will be made either in aluminum, stainless steel or in plastic. For the plastic backplates, they are usually made extra strong, in order to be tough enough inside water. For the aluminum plates, they have a coating that ensures they do not catch rust while underwater. The main aim of the backplates is to offer more support to the device and the tank.

Harness
The harness will also come in different forms and sizes, which are chosen according to the scuba dive’s specifications. The major aim of the harness is to offer more support to the bcd parts. They help to fix the D rings, weight pockets and the backplates as well, and deluxe harness with soft pads on shoulder belts, waist belts. Most of them can be adjusted to fit the diver perfectly and they also have some sort of cushioning, which offers more comfort when they are worn.

Inflators
Technically, there are two major types of Inflators that are used with the bcds. They include the manual and the power Inflators. The major aim of an Inflator is to fill the bcd with air, only that the mechanism of the two is different. To begin with, the power Inflator is linked to the tank, through a hose with a low pressure. You will only need to press the button, which will allow air to get into the device. Conversely, the manual Inflator, which is also called the oral Inflator, allows you to fill the device with air by blowing it. You will blow into the inflator hose through the mouthpiece. There is a button that locks the hose, which you will be needed to open it up and blow air through it. This Inflator is mostly linked besides the power Inflator button.

Weight pocket

There are some buoyancy compensator devices that use a fitted weight system, implying that there are some pockets that are specifically designed to manage the entire weight of the device. This also relieves the scuba diver from wearing weight belts. These pockets are designed to allow you put the weights in them and also, you can easily get rid of them whenever there is an emergency. A weight pocket is basically used to fit in weights that will help to manage the device while under water. The pocket is also well positioned to ensure that there is a weight balance of the scuba diver.

 Dump valve
This is another common part of the buoyancy compensator device, which help to release air from the bcd. They play the exact opposite role of the Inflator. They are also called the Deflators or the over pressure relief valve. There are the manual Deflators that will require you to press a button that is on the hose, which will allow air to flow out of the device. There is a way that you can easily release the air from the device, which is by moving upwards in a vertical position. As you are moving upwards, you will then lift the hose over your head, then push the button to release the air. Most of the bcd will be fitted with a single or more dump valves on them. The size of the bc device will determine the number of dump valves available. You will only need to pull the cord in order to release the air out of the bcd’s bladder. There can be a dump valve that is placed on the shoulder, usually on the left, in order to allow you to pull the cord with your right hand, in case of any emergency. Another sump valve will be placed on the lower part of the bc device. With this valve, you will be able to release the air when you are in an inverted position underwater.

Single tank adaptor
There are some bcds that use a single tank while in the water, while others will use two tanks. The single tanks are the most common, since they are mostly used with by the majority of the divers. The double tanks bcds are mostly used for deep sea diving, with the more experienced divers. There is a single tank adaptor, which is used with the single tank bcd. The adaptor is used to attach things that you might carry along underwater, such as cam straps, which will be linked to a backplate.

Fish tail
A fish tail is also among the common bcd spare parts that you can replace when the original fish tail is ruined. The fishtail help to support the cylinders on the sides and also, they hold them tightly at the back along the diver’s body line. They are well placed and designed to avoid drifting outwards or flapping together. The fishtail will be suitable for the open circuit technical divers, Rebreather divers, and any other exploration diver, including the cave divers. The fishtail will mostly be hardened on the inside, which helps to split the platform. It will be connected to the Rebreather and the harness, mostly to offer more support. They can be adjusted according to the user’s preferences and also, they can be used in different applications altogether.
