Buoyancy control device in short BCD, or jacket, is a system that allows a diver to control his or her neutral hovering while scuba diving.
Controlling your buoyancy underwater is an important skill, if not the most important, to master and to achieve positive, neutral or negative buoyancy as a diver to not bump into any corals, fish, rocks, sharks or turtles, and disturb or even worse destroy them. A perfect buoyancy control is essential for a Diver!
There are a few different types of BCD’s on the Market which I will explain here further down but first there are some technical terms on a BCD which are important to know if you’d like to invest in a BCD you’ll know what the description of a BCD actually means.
A scuba BCD is just an air bladder that lets you control your buoyancy underwater by inflating or deflating your BCD. The Bladder are air-filled pockets connected to each other which are surrounding you.
Besides controlling your buoyancy, scuba BCD’s also store your dive accessories, in Pockets with zippers or Velcro as well as D-Rings. Keep your regulators and octopuses organized and prevent them from dangling.
Buckles are made mostly from plastic and keep your BCD where it supposed to be, or make it easier to take it off or put on.
Cummerbund is a Velcro in front of your Belly it keeps the BCD on your back when diving and inflating so it doesn’t float off.
The BCD Backplate is mostly made of Plastic due to weight and holds your Tank securely with a strap if properly closed.
Some later BCD’s are weight integrated which means they have specialized pockets for carrying the Lead weights with a fast release mechanism in case of an emergency.
If in case you inflated the BCD with too much air you can pull the string of your Dump Valve and a valve placed on your shoulder will open and will let a lot of air out quickly. Mostly there is one on each shoulder where on the left shoulder its integrated in the inflator hose which you would pull to open it. On your right side it usually is a small button the size of a big marble to pull.
Some BCD’s also have a Dump Valve on the lower right bottom side in case you need to deflate while head over Diving.
These Dump Valves also act as over pressure valve in case the BCD is inflated to heavily.
An Air2 is a fully equipped Regulator which is attached to the end of the Corrugated tube and acts as an inflator/deflator and an emergency regulator in case your main Regulator fails.
Male or Female BCD?
Most BCD’s are unisex, meaning they work for both men and women. However, there are a few Lady BCD’s available. Because a women’s cut is narrower at the shoulder and wider at the hips than a mans.
The basic material used in the construction of BCD’s is nylon, or a variation often called. Cordura®, this being the brand name of a company that specializes in tough fabrics made from, among other things, nylon. Some manufacturers may highlight their extra polyurethane (PU) coating, which aids resistance to abrasion.
‘Denier’ is a term which may be more familiar to readers. It is a measure of how densely the fibers of a particular fabric are woven, with the lower end of the scale being less dense – and therefore lighter, but less durable – than the higher end.
Recreational Jacket Style BCD
Set up Travel BCD
This is the most common BCD type for warm water recreational diving. It is also the type that you were probably given to use when you got your scuba diving license. Many Dive Center use them to teach due to reliability and robustness. Also because it’s easier to learn buoyancy control in these type of BCD’s than in a Wing for example.
The air bladder wraps around the diver from the back to the front.
Packed Travel BCD
A travel BCD is like a normal diving BCD except more lightweight and smaller to pack.
Nowadays with most airlines charging exponentially excess luggage or reducing their free carry on luggage you are left with leaving some Dive Equipment at home or renting it expensive from the Dive Center but we all know that you’d rather use your own equipment which you are familiar with and know it does fit like a glove.
So now more than ever it’s important to look for light weight BCD’s
Semi Wing BCD
Semi Wing BCD
The design includes a Metal, Aluminum or Stainless Steel backplate, harness and detachable air bladd
Advanced divers might prefer Semi wing BCD’s because it allows for more arm movement and you can remain horizontal underwater.
This is because the air bladder is placed on the back.
The weight is also lighter than a normal style Jacket BCD while it is still equipped with D-Rings, Weight Pockets, and Side Pockets.
The design includes a Metal, Aluminum or Stainless Steel backplate, harness and detachable air bladder surrounding the backplate.
This type of BCD originates from technical diving, where divers are using a twinset of two tanks or a rebreather. In recent years, wing-style BCD’s have appeared in single-tank diving and made its way into recreational diving.
Like a jacket Style BCD the shape is still like a sleeveless vest with pockets around the waist but the front is more streamlined because there is no air bladder in the front.
Due to a very small water resistance, low drag reduces the effort needed to move through the water. The less effort, the better our air consumption and the more time we get on our underwater adventure. However the Wing Style is more expensive and has less storage space if at some at all.
The Stabilizing Jacket remains the BCD style choice of experienced and professional divers because of its dynamic control system. Stabilizing Jackets reject the idea of air bladders within BCDs; instead, they use internal air passages that basically embrace the diver and allow air to remain dynamic inside the jacket. This air flows freely to the jacket’s highest point, which allows the diver to basically rotate around a bubble. This adds stability and creates ease of motion for the diver.
Care and cleaning
After a dive in salt water, fresh water or a swimming pool, you should always rinse the jacket thoroughly with fresh water; you should operate all drains and inlets while rinsing so that the remaining salt water or residual dirt is flushed out.
BCD’s should also always be rinsed inside. Because every time you press the inflator while diving, some salt water runs backwards into the bladder and it collects there.
Hold the water hose on the inflator opening and press it until some water has collected inside the BCD. Then the BCD is shaken back and forth so that the fresh water that has just been poured in, is distributed in the BCD and the salt water is rinsed out.
To get the water out of the BCD, the BCD is inflated with a little air by the inflator and turned upside down so that the inflator is the lowest point of the BCD then just press the inflator button so that the water can run out. This can be repeated two to three times depending on how much the jacket has been used and how long you want to store it.
Then you should inflate the BCD a little and hang it up to dry for about 1 week, depending on the environment, before stowing it.
