It is very common for people who are not confident swimmers to use a life jacket while snorkeling. In many tour boats, life jackets are given to everyone. In shallow water that, in an emergency, you could stand up in, they are not necessary. (Though there could be a lot of good snorkeling at that depth.)
I lost my snorkel; then surfaced.
a snorkel
Snorkel is not a German word, therefore; it has no meaning in German. In English, a snorkel is a tube that swimmers/divers use to breathe underwater. It's part of their diving masks. The English verb to snorkel is the actual act of swimming/diving with the snorkel. To say snorkel in German, the verb is schnorcheln, and the noun is der Schnorchel.
yes they canys they use there trunk like a snorkel
yes you can, as long as it is completely sealed.
Swimming with a snorkel for the first time can be quite daunting.
Technically, no. A snorkel is merely a breathing apparatus that allows one to breathe while one's face is below water. You could use a snorkel while walking or crawling in shallow water. Still, it'd be a far better idea not to be in water deep enough to snorkel in without some ability to swim.
No, it will only work if the top of it is sticking out of the water so unless its a really long snorkle,,, no
oxygen is used for many different things such as breathing we breath oxygen out and in also divers use a snorkel which gives them access to breath under water for an amount of time
If you intend to do the crawl stroke, I find the mask to have too much water resistance to swim forward AND turn the head to breathe. You will find the head will just not turn. If you do not intend to turn the head (and use the snorkel instead), the mask may still have more forward resistance than you would like, tending to feel like someone is pushing the mask downward toward your chin. I would recommend goggles with or without a snorkel. It is possible to use goggles with a snorkel.
Breathing underwater can be difficult if you do not have the right equipment. A snorkel can help you to breath or you could use a scuba diving mask with oxygen.
There is no record of how many people use it.
