Snorkeling wouldn't be possible without its namesake piece of equipment: the snorkel. In some places, snorkels are even mandatory for recreational diving. This important piece of equipment comes in the form of a curved tube with a mouthpiece that allows the diver to breathe while the nose and mouth are submerged. There are countless types of snorkels on the market to fit anyone's needs.
The most popular type is a snorkel with a one-way purge valve. A purge valve is usually located beneath the mouthpiece and allows the diver to easily clear the tube of water. Since the valve is one-way, water can only travel out of the snorkel which means the chance of swallowing water is eliminated. Another type is the open-top snorkel. Like the name suggests, this type of snorkel has an open top. Although this makes the snorkel less bulky, it also means pesky water can splash inside the snorkel.
Finally, dry and semi-dry snorkels are other types you may encounter. Dry snorkels have the ability to stay completely dry when the diver dips below the surface of the water. They're able to do this due to different mechanisms at the top that seal water out when submerged. Similarly, semi-dry snorkels keep most of the water out of the tube. When you find the right snorkel type with a comfortable mouthpiece, you'll be sure to have a great water adventure.
