Vest Style BCD versus Back Inflation

BCD stands for buoyancy control device and it is perhaps the most essential pieces of equipment that you will utilize while diving. Knowing whether a vest style or back inflation BCD is right for you is important and can help you have a more enjoyable and safe diving experience. Choosing the best BCD for you is often difficult, but the information below can help you understand which style would best suit your needs.

Back Inflation BCD Definition

A back inflation BCD is one that is worn on the back of a diver, much like a backpack. It has an air compartment that only inflates in the back of the body and then the air cells hang behind a diver and often look like wings.

Definition of a Vest Style BCD

The vest style BCD is worn just like a vest and is the more traditional option. This type of BCD features air cells that inflate in the back of the diver and then wrap around the shoulders and chest as well.

Which is the Best BCD for You?

There are a number of factors that determine the best BCD for you. A lot of the decision depends on the type of diving you will be doing, while another part of the decision focuses on the various features you are looking for.

For instance, if you are looking for a BCD that will easily allow you to float on the top of the water, then a vest style may be the best BCD for you, as it will naturally hold you vertically up on the surface. A back inflation device will instantly propel you face down, but you can change this if you lean back as you float on the surface, making it just as functional.

When moving underwater however, a back inflation BCD is usually more helpful in propelling you through the water and decreasing the amount of air you use. The vest style BCDs often put you in a position where you fins are pointing down and this is less efficient and makes it more difficult for you to navigate through the water.

If you are searching for a device that is able to deflate quickly, then you may find that the best BCD for you is a vest style device. The air cells on the chest of the vest style products all have straps that press against the cells and make it easier to deflate. The back inflation devices do not have these straps and the air cells hang freely behind a diver making it a little more difficult to inflate completely.

It is important to gather an adequate amount of information before choosing the best BCD for your diving experience. Testing out both a back inflation and chest style BCD before making your final decision is also a great way to know which style would best fit your diving needs. A trial run along with the information above can help you reach a final decision and make an informed choice.
