Gearing Up for the Dive - The Snorkel
There used to be a time when scuba divers bring snorkels with them when they dive. However, the gear has become less popular in scuba diving for obvious reasons. What use do you have for snorkels when you have the scuba? Snorkels are cumbersome, annoying, and rarely needed. Even so, most certifying agencies still require the use of the snorkel and for good reason: The snorkel allows you to swim with fins for long distances, while keeping the head looking down and never having to come up for air. Keeping that in mind, you still may want to purchase a snorkel, if not for scuba diving, then for skin diving. You never know when you need the gear. Make Sure the Bore of the Snorkel is the Right Size The bore is that end of the snorkel that remains above the water. It is where air passes through when you suck through the mouthpiece. So you can see how important it is that the bore should be the right size. If it is too small, not enough air will pass through, making it hard for you to breathe. You will know when the bore is the right size if your thumb fits snugly in the top. Don’t make the bore too large either because it would be hard for you to expel the water after surfacing. Watch for the Flexible Section Near the Mouthpiece If you plan to carry the snorkel when scuba diving, then this is an important feature to look for. It allows the snorkel to hang straight when not in use so that it won’t get in the way with the scuba regulator. In most snorkels with this feature, the flexible section is often corrugated. That way, even when it is bent, it won’t close. But make sure that the corrugations do not continue on the inside because water may trickle down the grooves and get into your mouth. Purge Valve The purge valve is usually a one-way flap at the bottom. It makes it easier for you to get rid of the water when you surface. But remember that water in the snorkel will only fall to the level of the ocean’s surface so you would have to expel the rest by forcefully exhaling. |
