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...



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. You want a good quality mask that fits you well and gives you the best viewing area possible, because you don’t want to miss anything underwater. Visit or ask Da Nang Scuba's experts to get advice about to try on a scuba mask.

Standard Mask Features

  • Tempered-glass lens for safety, or lenses made from really strong, high-quality composite materials.
  • Comfortable, feathered, double-skirt made of soft silicone rubber.
  • Enclosed nose so that you can adjust for pressure changes by exhaling.
  • Finger pockets around your nose so that you can equalize your ears.
  • Low profile for easier clearing of water and a wider vision field.
  • Adjustable strap that can be locked in place.

Optional and Desirable Mask Features

  • A purge valve is a one-way valve used to clear water from a mask.
  • If you wear glasses, some masks are specifically designed to fit prescription lenses. Consult with a dive professional at Da Nang Scuba.
  • Black versus clear or translucent silicone rubber.
  • Mask strap made from wetsuit material that connects and adjusts using Velcro®.
  • Colored lenses or special anti-reflective lens coatings.
  • High-tech, heads-up display that allows you to check critical dive data.

How to Choose Your Scuba Mask

With the wide variety of masks available today, it will be more difficult to decide which one you like best rather than finding one that fits and is comfortable.

  • Hold the mask gently against your face with the strap looped in front, out of the way.
  • Gently inhale through your nose. If the mask stays there – no air leaking in and you don’t have to continuously suck in through your nose – then it should create a seal for you.
  • Check to see that the mask skirt rests evenly against your face along the entire edge. Mustaches and beards make finding a good seal a little more difficult, but still possible.
  • Adjust the strap, put the mask on and evaluate how the mask feels on your face – it should be comfortable.
  • If you can, attach a snorkel to the mask and put the mouthpiece in, or put a scuba regulator in your mouth. This should not significantly change how the mask fits.
  • Try pinching your nose.
  • Look around – straight ahead, up, down, sideways – to see if there are any annoying blind spots.
  • Try on several masks and narrow down your choices by fit and comfort. Don't sacrifice fit and comfort for price.

Take Care of Your Mask

  • Most new masks’ lenses need a scrub before use because the glass gets stuff on it during manufacturing. The dive center staff and the manufacturer will have various recommendations.
  • Before every dive, apply a defog solution to your mask lens.
  • Be familiar with your mask strap adjustment and locking device so that you can make quick adjustments at the dive site, if necessary.
  • Rinse thoroughly with fresh water after each use. Keep out of direct sunlight as much as possible. Store in a cool, dry place.
  • Keep your clear silicone out of contact with anything neoprene, like black scuba fins, because neoprene leaches into the silicone and discolors it.
