Your Scuba Gear


A mask is one of the most important, and personal, pieces of scuba diving equipment you own because it lets you explore with your eyes. More...


A snorkel is a very personal piece of equipment. It lives with your mask, spends time in your mouth, and lets you breathe while you look below, until you’re ready to submerge on scuba. More...


There are fins for swimming, snorkeling, free diving and body surfing. More...


Imagine scuba diving while hovering, weightless underwater – eye to eye with a fish. How is it possible? It starts with your buoyancy control device (BCD). More...


Most people float, which is great if you like to stay at the surface. However, scuba divers want to descend and need a weight system to help them offset this tendency to float. More...


If you think about it, breathing underwater is pretty remarkable, and it all happens because of the regulator. The scuba regulator is a great invention that delivers the air from your scuba tank to you just the way you need it to breathe. More...


Your SPG displays how much air remains in your tank so that you can end your dive well before you get too low. More...


You can track your dives using dive tables, a depth gauge and dive watch, but most scuba divers use a dive computer – it’s easier. More...


In the 1970s and 1980s, divers wore dive watches because it was the standard way to track bottom time while scuba diving. More...


A dive knife is a general tool that scuba divers occasionally use to cut entangling fishing line or rap on their tanks to get a buddy’s attention. More...


It’s obvious that a dive light is necessary to scuba dive at night to help you navigate, see your gauges, and observe interesting aquatic life. More...


Whether you’re driving to your local dive site or getting on a plane headed for the tropics, a sturdy gear bag will help you organize, protect and carry your scuba diving equipment. More...

It’s called exposure protection because while scuba diving you’re not only exposed to water’s cooling ability but also to things that can scrape, cut or sting. More...


With the rise of digital photography capabilities, there are now numerous options for capturing images underwater. More...


An accessory is defined as an item that can be added to something else to in order to make it more useful, versatile, or attractive. More...


A dive flag indicates that scuba divers are nearby. In some areas, flying a dive flag while scuba diving is required by law, but in general it’s a good idea for safety reasons. More...


In the unlikely event that you’re at the surface and need to get the attention of someone on shore or on a boat, you’ll be glad you have a surface signaling device. More...


High-pressure cylinders are relatively small, yet very strong containers that hold large volumes of compressed gas. More...


Scuba diving with a sidemount configuration simply means that you carry your tanks at your sides instead of on your back. More...



Imagine scuba diving while hovering, weightless underwater – eye to eye with a fish. How is it possible? It starts with your buoyancy control device (BCD).

A BCD does exactly what its name describes – it gives you control in the water. Sometimes you want to float on the surface comfortably. Occasionally, you want to kneel or stand on the bottom, sometimes during a training course. Most of the time, you want to drift along effortlessly mid-water, observing the scenery. To do this efficiently, you need a BCD that fits you well, along with a weight system to fine-tune your buoyancy. The BCD also holds your tank. Visit or ask Da Nang Scuba's experts to get advice about BCDs.

Standard BCD Features

  • Expandable bladder
  • Low-pressure inflator and oral inflation mechanism
  • Deflator mechanism and overpressure valve
  • Adjustable straps, buckles, bands or releases
  • Adjustable tank band and sturdy back plate

BCD Styles

  • Jacket style – most popular for recreational scuba diving. Some made specifically for women.
  • Wing (back-mount) style
  • Traveling BCDs – made of lighter materials
  • Technical diving systems combine wing-style bladders with harness setups
  • Sidemount divers combine a back wing with a harness system that mounts tanks to your sides.

Optional and Desirable BCD Features

  1. Integrated weight system
  2. D-rings, clips and hose retainers
  3. Pockets
  4. Alternate inflator regulator combines your alternate air source with the BCD inflator

How to Choose Your BCD

  1. Choose your BCD based on where you’ll use it most, and then make sure it fits.
    1. With a style in mind, try on the BCD for size. If in doubt, try on a few sizes. If you’ll wear a dry suit or thick wetsuit, consider wearing it to get the right fit.
    2. While wearing the BCD (and maybe gloves if you usually dive with them):
      • Tighten and loosen, clip and unclip every strap and release on the BCD.
      • Play with the inflator and deflator mechanisms.
      • Orally inflate the BCD completely and make sure it’s still comfortable, not restrictive.
    3. Check that the BCD’s inflator hose is compatible with your regulator setup.
    4. After trying on a few BCDs, narrow down your choice by fit and comfort. Then, make the final decision based on style, color, optional features and personal preference.

    A BCD is an investment that should last for several years, so don't sacrifice fit and comfort for price.

Take Care of Your BCD

  • Rinse thoroughly with fresh water after each use – both outside and inside.
  • Let the BCD dry completely – out of direct sunlight as much as possible.
  • Partially inflate the BCD and store in a cool and dry place. Don’t leave weights in the weight pockets.
