Types of Snorkels

Snorkeling gives vacationers a window into the exciting world beneath the waves. Scuba divers also use snorkels on the surface to conserve their air. When choosing a snorkel, it's important to understand your options and find the model that will work best for you.

  1. "J" Snorkel

    • At its most basic, a snorkel is a curved tube that allows you to breathe air from the surface while your face is underwater. A "J" snorkel is so named because it follows the shape of the letter J, and is the most simple snorkel available. They are rigid plastic tubes fitted with a mouthpiece. They are inexpensive and easy to maintain.

    Flexible

    • The most popular type of flexible snorkel features an accordion-like piece between the barrel and mouthpiece. This allows the mouthpiece to swing out of the way when it's not being used. Scuba divers often prefer this, since they use the snorkel only on the surface. Other types of flexible snorkels include some that either fold or roll into a ball, allowing them to be stowed easily for travel.

    Dry/Semi-Dry

    • A dry snorkel has a floating mechanism that blocks the entrance to the barrel when the snorkel is submerged, or when a wave crashes over it, preventing water from getting in. This mechanism reopens when the snorkel is at the surface. Dry snorkels work especially well for freediving. Semi-dry snorkels have a splash guard or wave guard to protect the top of the barrel, minimizing the amount of water that enters. It's easier to clear water from these snorkels, but they are larger, which causes more drag.

    Purge Valves

    • Some snorkels have a one-way opening at the bottom, below the mouthpiece. It allows water to fall out the bottom of the snorkel when the diver returns to the surface. This means less water needs to be moved out the top of the snorkel, so clearing requires less force.

    Other Considerations

    • When purchasing a snorkel, check the size of the bore (the barrel). If it is too small, it will be difficult to get enough air. If it's too wide, clearing water will be harder. The length of the snorkel is important too. Too short, and it won't reach above the waves; too long, and it may cause water to leak into your mask by pulling away from the face. A long snorkel also allows carbon dioxide to accumulate.

      Check the mouthpiece to be sure it's comfortable. Make sure, if you're purchasing a snorkel that's reasonably expensive, the mouthpiece is removable, so you don't have to buy a whole new snorkel when it is worn out. On an inexpensive snorkel, this won't matter as much, since replacement cost is minimal.

      Make sure the "snorkel keeper," or attachment mechanism, works with your mask. Some rubber or silicone keepers are difficult to move once they're in place, while others slide off too easily.

      As with any piece of equipment, consider the conditions under which it will most likely be used. This should help you decide which snorkel type is most appropriate.
