In a previous post, we discussed the Basics of a Buoyancy Compensator, how it is used, and the Types of BCDs. 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 the range of choices out there.
Here are 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 straightforward, and you’re looking for comfort when you dive. If you have ever gone diving with a rental that didn’t fit well, either too loose or too tight, you spend a lot of time adjusting, which just takes out of the fun of the dive.
When inflated, a loose BC will ride up your arms and pull your tank up to your head level, making it uncomfortable to turn. If that’s the case, you also tend to adjust a lot during your dive. 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, try the buoyancy compensator and consider how it feels. Inflate it to see whether it feels tight. Move 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 alone should not be able to slide on your body from side to side.
Lift Capacity
Lift capacity is not as important a consideration for recreational diving, but it is always good to know. It is typically determined by floating an inflated BC and adding weight to it until it sinks. An average BC’s lift capacity is in the 30-40 lbs. range. Most BCs will have sufficient lift for the average diver.
When it comes to the cave, wreck, or technical diving, if you plan on carrying extra gear and more than one tank, the lift of the BCD is 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 is in a good place for easy access. Check the closures, whether buckles or zippers 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 BCDs come with an integrated weight system, which is essentially weighted to render your weight belt unnecessary. Not needing the traditional weight belt can be cool, as you won’t have to worry if you forget your weight belt or if the weights slide around when you dive.
You do have to pay attention to whether it can hold the weight you require for the type of diving you do and 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 may be worth the little extra.
Air Dumps and Pressure Release Valves
An extra air dump is not a necessity or requirement, but it could be a nice feature. If it’s situated by your shoulder or near the bottom of the BC, for instance, you can 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 they are easily accessible.
Whatever the style and feature of the Buoyancy Compensator, fit and comfort are the most important factors. Hopefully, these few points will make choosing the right BC easier for you.
