The snorkel can make it easier for you to swim back on the boat or on the shore, and your face can naturally be placed in the water. When there is a storm on the surface of the water, the height of the orifice that can be used with the breathing tube is usually higher than the height of the wave to avoid letting water flood into the mouth. So, why do you know the goggles with a breathing tube? Now let's take a look at the extreme sports safety tips in this area.
The snorkel is designed with many factors in mind. The full-function snorkel should include: nozzle stop valve, mirror buckle, adjustable threaded tube, oral drain valve, and the water in the nose of the mirror is your face mirror. The air tightness is not very good. It is also normal to have the mirror water in the diving. It is enough to do the mirror drainage. The best way to avoid nose water is to do the mirror drainage, a lot of practice, and then get used to a little bit of water in the mirror. You may think, since scuba diving has cylinders and regulators, Why is the breathing tube one of the standard equipment?
Because, first of all, when your face is resting or swimming, your face is looking down or looking for something in the water, you can breathe through the breathing tube to reduce the air consumption in the cylinder.
Second, when there is a storm on the surface of the water, the height of the orifice that can be used with the breathing tube is usually higher than the height of the wave to avoid letting water flood into the mouth.
Third, if you are out of the water away from the boat or the shore, and the air in the cylinder is running low, the breathing tube can make it easier for you to swim back on the boat or on the shore, and your face can naturally be placed in the water. While snorkeling, the breathing tube is a must-have, so you don't have to look up and stay in the water for a whole day.
The general breathing tube design is open at one end and the other end is a bent tube with a mouthpiece. The upper part of the breathing tube (tube body) is usually a semi-rigid plastic tube, and the lower part of the mouthpiece is made of silicone.
A suitable snorkel should have a proper curvature (suitable for your own face), with an inner diameter of about 2 cm and a length of 30 to 35 cm. A suitable snorkel is easy to breathe in addition to comfort. When you try it out, you can place the mouthpiece between your lips and your teeth. Place the tube body in front of your left ear. The mouthpiece should be comfortable, not scratching your mouth or causing chin fatigue, and it should be straight in your mouth. of.
Snorkel selection Snorkels are generally used with a face mirror. The breathing tube allows snorkelers to bury their heads in the water and enjoy the underwater landscape without having to look up frequently.
For divers, when floating on the surface before diving, you can use the breathing tube to breathe directly without wasting the precious air in the cylinder. The early snorkel was only a combination of a curved tube and a mouthpiece. However, in recent years, there have been many design improvements in the snorkel. For example, some have added a wave cover at the top to reduce seawater entering the breathing tube, or at the mouthpiece. Part of the increase in the drain valve, and even some of the breathing tube has a dual drain valve design, greatly improving the drainage efficiency.
The strength of a breathing tube depends on the comfort of use and the level of drainage.
The following principles can be followed to select a snorkel:
First: the diameter of the pipe is large.
Second: The length is preferably 30 to 40 cm. Too long a breathing tube will increase the breathing dead space and reduce the efficiency of ventilation.
Third: a moderately sized, comfortable mouthpiece. It is best to use a silicone mouthpiece because it is soft and non-toxic. Some of the lower part of the breathing tube has a flexible hose or a design that can be adjusted to the face to increase the comfort of use.
Fourth: whether the breathing tube has a special design to improve drainage efficiency
In short, the snorkel is a device that allows the snorkeler's face to remain in the water and still breathe. Divers should master the knowledge of what we should pay attention to when diving. Family members should stay with them, pay attention to travel safety and protect their health.
