In a previous post we discussed the Basics of a Buoyancy Compensator, How it is used and Types of BCD’s.  Buoyancy Compensators are among the most expensive pieces of equipment a diver uses. If you are taking the step to own your entire dive kit, you need to know exactly what you’re looking for and your range of choices out there.

Here’s a few points you must consider while choosing a Buoyancy Compensator or Buoyancy Control Device.

Fit
This is probably the most important, as recreational diving is pretty straight forward and you’re looking for comfort when you dive. If you have ever gone diving with a rental that didn’t fit well, either it was too loose or tight, you spend a lot of time wasted on adjusting which just takes out of the fun of the dive.

A BC that is loose, when inflated will ride up your arms and it also pulls your tank up to your head level making it uncomfortable to turn. You also tend to adjust a lot during your dive if that’s the case. A tight BC on the other hand can be more harmful than just uncomfortable. When inflated it can squeeze you and restrict your breathing.

So first thing, try the buoyancy compensator on and consider how it feels. Inflate it to see whether it feels tight then. Moves your arms and check if it’s constricting movement in any way. It should fit comfortably -not too tight across the shoulders, under the arms or around the waist. You should be able to move in it but the jacket by itself should not be able to slide on your body side to side.

Lift Capacity
Lift capacity is not as important a consideration for recreational diving, but it always good to know. It is typically determined by floating an inflated BC and adding weight to it until it sinks. An average lift capacity for a BC is in the 30-40 lbs. range. Most BC’s will have sufficient lift for the average diver.

When it comes to cave, wreck or technical diving and if you plan on carrying extra gear and more than one tank the lift of the BCD is more crucial and should be considered accordingly. Ask the expert at the dive store to determine the lift of the BC you’re looking at purchasing.

Pockets, Buckles, Velcro and More
It’s a good idea to check if the BC you are considering has sufficient pockets and that they are in a good place for easy access. Check the closures, whether buckles or zipper and the velcro that usually straps across your waist. Check that it comes with enough rings to attach your other equipment, if not you can add some on.

Weight Integration
Some of the more modern styles of Scuba BCD’s come with an integrated weight system which are essentially weighted to render your weight belt unnecessary. not needing the traditional weight belt can be a cool thing as you won’t have to worry if you forget your weight belt or of the weights sliding around when you dive.

What you do have to pay attention to is whether it can hold the weight you require for the type of diving you do as well as whether the weight can be easily released in case of an emergency. While you need one less piece of gear (a weight belt), they do cost a bit more than your regular BC. It maybe worth the little extra.

Air Dumps and Pressure Release Valves
Not a necessity or requirement but a feature that could be nice to have is an extra air dump. If it’s situated by your shoulder or near the bottom of the BC, for instance, you will be able to release air no matter what position you are in.

It’s more important to consider where your pressure release buttons on the BC are located and whether easy accessible.

Whatever style and feature on the Buoyancy Compensator, the fit and comfort is the most important. Hopefully these few points will make choosing the right BC easier for you.
