How to Choose a Good BCD? [GUIDE]


BCDs come in all shapes, sizes, and colours, each with its own set of unique features. With all these options people often get confused about which BCD is best for their needs. So, we're here to guide you through the murky waters and help you make a splash with your choice. So, buckle up and let's dive in!

Choosing a Good BCD

Choosing a good BCD is not just about picking the one with the flashiest colour or the highest price tag. It's about understanding your needs as a diver, knowing the features that will serve you best, and finding a BCD that fits well and feels comfortable.

Understanding Your Diving Needs

Before you can pick the perfect BCD, you need to understand your own diving habits. Are you a recreational diver who prefers warm, calm waters? Or are you an adventurous soul, always seeking new depths in cold, challenging environments?

Your diving needs will determine the type of BCD you should go for. For instance, if you're mostly a recreational diver, a jacket-style BCD might be your best bet. On the other hand, tech divers often prefer back-inflate or wing-style BCDs.

Features to Look For

Not all BCDs are created equal. Here are some features to consider:

  • Integrated Weight System: This feature allows you to ditch your weight belt. It's easier to manage, and you can drop weights quickly in an emergency.
  • Lift Capacity: This determines how much weight the BCD can offset. Make sure it can handle your equipment and any extras you may carry.
  • Pockets and D-rings: If you're the type who likes to bring along gadgets or collect souvenirs, look for a BCD with ample storage options.
  • Size and Fit: A good BCD should fit like a glove. It shouldn't restrict your movement or breathing, nor should it float up around your ears when inflated.

Quality and Durability

When it comes to BCDs, quality can't be compromised. Look for durable materials, sturdy construction, and reliable brand names. Check reviews and do your research.

Different Types of BCDs

BCDs come in different types, each designed for a specific kind of diving. Let's take a closer look:

Jacket-Style BCDs

These are the most common type, particularly for recreational divers. They're easy to use, comfortable, and provide good stability and lift.

Back-Inflate BCDs

This type provides more freedom of movement in the front and tends to position the diver horizontally, which is ideal for experienced divers.

Wing-Style BCDs

These are favoured by technical divers. They offer excellent horizontal trim and freedom of movement, but they require more skill to control buoyancy.

Choosing the Right Size BCD

A BCD that doesn't fit well can ruin your dive. Here's how to get the right size:

Check the Size Chart

Manufacturers provide size charts based on height, weight, and chest measurements. Use these as a guide, but remember that fit can vary between brands.

Try It On

If possible, try the BCD before you buy. Check the fit and comfort, and practice inflating and deflating it. Make sure the straps are easy to adjust and the pockets are within reach.

Test It In the Water

The ultimate test for a BCD is how it performs underwater. If you have the chance, rent the BCD model you're interested in and give it a whirl in real diving conditions.

Caring for Your BCD

Once you've chosen your BCD, you'll want to take good care of it. Proper maintenance can extend the life of your BCD and keep it performing at its best.

Rinse and Dry

After each dive, rinse your BCD thoroughly with fresh water to remove salt, chlorine, and any debris. Allow it to dry completely before storage.

Inspect Regularly

Check your BCD for any signs of wear and tear before and after each dive. Look for leaks, loose straps, or damaged buckles.

Annual Service

Get your BCD serviced by a professional annually. This will ensure all the valves and inflator mechanisms are working properly.

Top BCD Brands to Consider

Q: What is the main purpose of a BCD?

A: The main purpose of a BCD (Buoyancy Control Device) is to help divers maintain neutral buoyancy underwater and positive buoyancy on the surface. It allows divers to ascend, descend, and hover with ease.

Q: How often should I replace my BCD?

A: With proper care and maintenance, a good quality BCD can last up to 10 years. However, this can vary depending on usage and care.

Q: Can I use a BCD for snorkelling?

A: While you technically can, it's generally not recommended. BCDs are designed for scuba diving and may be too bulky and heavy for snorkelling.

Q: Does the colour of my BCD matter?

A: Colour is more a matter of personal preference. However, brightly coloured BCDs can enhance visibility underwater.

Q: How do I know if a BCD fits properly?

A: A properly fitting BCD should be snug but not too tight. It should not restrict your movement or breathing, and it should stay in place when inflated.

Q: Is it better to rent or buy a BCD?

A: If you dive frequently, it might be more cost-effective to buy your own BCD. This also allows you to become familiar with your gear and ensure it fits perfectly.


Choosing a good BCD isn't rocket science, but it does require a bit of homework. You need to know your diving needs, understand the different types and features of BCDs, and find the one that fits you like a second skin. Remember, the best BCD is the one that makes you feel comfortable, confident, and ready to explore the underwater world. So, take your time, do your research, and make a splash with your choice!
