The right snorkel for me
"A snorkel must fit comfortably in your mouth, allow you to purge water out of the mouthpiece and hose quickly and help you to swim efficiently. But, the most important characteristics to remember when choosing a snorkel are its length and the diameter of its barrel.
Snorkels must not be too long or too short. If a snorkel is too long it will be difficult to breathe because the barrel will fill up with carbon dioxide. Every time you breathe out carbon dioxide through your snorkel your breath must travel up and out of the barrel of your snorkel to allow you to draw oxygen back down the barrel and into your lungs. If your snorkel is too long you will only push a percentage of the carbon dioxide up and out of the barrel during your exhale. You will need to inhale oxygen before all the carbon dioxide has been pushed out; leaving the percentage of carbon dioxide entering your bloodstream higher each time you take a breath. This cycle could lead to suffocation. If a snorkel is too short it will constantly fill with water, requiring you to constantly force the water out of your snorkel which can be very exhausting.
The inside diameter of your snorkel must be approximately three quarters of an inch or 1.9 cm. If the snorkel is thinner than .75 inches it will be difficult to breathe because there will not be enough room in the barrel for you to draw enough air into your lungs. This will cause you to breathe harder and rapidly, which could cause hyperventilation. If the barrel is thicker than .75 inches it will be too large and will be uncomfortable to use and attach to your mask.
Learning to attach your snorkel to your scuba mask to make sure it is easy to grab and use is an important part of safe scuba diving practices. Snorkels are attached to the left side of your mask with a snorkel keeper. Snorkel keepers are either plastic or rubber and most use a post-hole closure. Each snorkel keeper is different and attaching your snorkel to your mask with a snorkel keeper requires practice. If you will detach your snorkel from your mask after each dive you should practice attaching your snorkel, as it can be a little tricky. Alternately, you can leave your snorkel attached to your mask if you are diving more than once in a day.
