The famous Greek conquerer and king, Alexander the Great promoted the invention of the diving bell in 333 B.C., which was designed to do two things: help divers reach deeper depths through weight, and also provide enough air for the diver to continue breathing during his dive without resurfacing. However, the dead space concern described above necessitates making the tube narrow enough to reduce the accumulation of carbon dioxide. If you really struggle with using the center mount snorkel, perhaps the issue is that you are afraid of getting water into the tube and choking on it. For example, I've been always using only my mouth to breathe in and out of the snorkel. In 1300, Persian divers began using tortoise shell to create goggles by slicing the shell so thin that it became translucent, and then polishing it. Along with a set of goggles and earplus, it has traveled extensively with me over the last twelve months and I suspect will do so for a long time yet. The last version, called bi-fins, takes place on the surface, employs a mask, snorkel, and pair of fins. Instead of the snorkel coming around the side of the face as is traditional with a divers snorkel, the Swimmer's Snorkel exits the mouth and runs straight up over the nose protruding from the water above the head.
The surface swimming version involves the use of a mask, snorkel, and monofin, and stipulates that swimmers remain at the water's surface except when turning. Second, the snorkel serves as a sensory cue to keep one's head down while swimming. As the name indicates the front mount snorkel attaches to the front of the head instead of the side like regular scuba or snorkeling snorkel equipment. If the head strap feels too tight, press the "button" on either side where the straps connect to the front of the head strap to loosen the straps. Use a phillips head screwdriver to tight down the screw that you'll find where the head mount and snorkel tube meet. After removing it from the packaging, you'll notice that the swimmer's snorkel comes shipped with the snorkel tube and the head strap as separate pieces. In the most basic snorkels, youth warmups consisting only of a simple tube and mouthpiece, the user can clear water that accumulates in the snorkel one of two ways.
There are two basic ways. These mechanical clearing mechanisms are prone to malfunction if they are not used frequently, however, and typically do require slightly more respiratory effort than would otherwise be needed. However, the variation comes in when we talk about exhalation (getting rid of your air or blowing the air out of your lungs). My teammate and friend, Dan, has not bonded with his snorkel because he can't figure out how to turn with it. Third, it is just plain fun to swim with a snorkel and it breaks up the monotony. The third, immersion swimming, uses a mask, monofin, and an underwater breathing apparatus. Mike Bottom, Head Coach of the World Sprint Team and Co-Head Coach at UC Berkeley, uses the Swimmer's Snorkel with all his top sprinters and estimates they use the snorkel during practice 25-30% of the time, every day. The Italian physicist Guglielmo de Lorena drew on these designs when he created the first functioning diving helmet in 1531 or 1535. This barrel-shaped bell would fit over the user's head and allow them to breathe while submerged. FINIS created and patented the first ever center-mount snorkel designed specifically for swimmers. The Swimmer's Snorkel can be incorporated into a training regimen so every warm up and swim down enables concentration on proper body alignment, complete axis rotation and arm stroke pattern to make them automatic.
The Swimmer's Snorkel allows swimmers to focus on stroke technique without the interruption of turning the head to breathe. Loosen them until the head mount feels comfortable. It also has a more of a streamlined shape where the tip bends towards the back of the head and the snorkel body is flatter instead of round. So what is the key take away from all this breathing through swimmer's snorkel stuff? Setting up the Kraken Aquatics Swimmer's Snorkel is pretty quick and easy. If you plan to wear a cap and/or goggles, be sure to put those on before you put the swimmer's snorkel on. All that is left to do is to get out and use your new swimmer's snorkel. In that case, you should check out the Dry Top attachment. If you use the snorkel to improve some part of your stroke and do not want to worry about getting into an oxygen debt, then breathe out through your nose (if you can master this technique).
