The Buoyancy Control Device, or BCD, is like the main pillar of the diving suit. It helps hold the diving tank and hold the antenna cable. Some models have built-in ports. And most importantly, it can collect, release, or add air. To help the diver Maintain neutral buoyancy while diving.
BCDs can be divided into 3 main types:
BCD Jacket
Adjustable Front BCD
Reverse Inflatable BCD
BCD JACKET
Although this type has been used for a long time, BCD Jackets are still popular with divers today. With ease of use Can add more air And there is no difficulty in adjusting the fit Since Scubapro introduced the first BCD Jacket 40 years ago, it has been a revolution in diving equipment by default. With higher buoyancy stability The unique design of the fully connected air chamber This allows air to move throughout the entire set. Keeping balance underwater And floating on your back on the water is easy. Today, Scubapro’s BCD Classic retains the timeless design of the BCD Jacket combined with new technology that makes this BCD even more durable. Equipped with a valve designed to allow more air to be received, the Scubapro Classic still holds a place in the hearts of BCD Jacket fans to this day. FRONT ADJUSTABLE BCD
Most (among Thai divers or even foreigners) we still call this type of BCD a Jacket BCD, but even so, the front adjustable BCD has some subtle details that are quite different from the Jacket BCD. With this type of BCD, the size can be adjusted to fit the user. Regardless of the position of the shoulders, chest and waist, the diver can feel comfortable. But there are still airbags under the arms and waist. Examples of front adjustable BCDs include the Hydros mountaineering.andGlide
BCD PUMP BACK
Just by the name, it is clear that this type of BCD has only one air chamber on the back. The bulkiness in front of the body disappears. Helps to significantly reduce drag when in the flow area. Compared to other types of BCDs, Back-Inflate BCD gives you the same knowledge as not wearing a BCD. Seahawk2 or Hydros Pro is one of the best Back-Inflate BCDs favored by divers. and underwater photographers, however, due to the air vent on the back Makes you have to practice floating on the water. And pay a little attention to the lead addition. But that is not considered a factor that makes this type of BCD less popular.
