Can you scuba dive by using a garden hose?

No.

Years ago, when I took my very first scuba course, the instructors had us walk from the shallow end of a pool to the deep end, wearing a weight belt and breathing through a very long snorkel. Nobody got all the way to the deep end before it became impossible to breathe against the increasing water pressure. It was a very effective exercise in that it taught us very quickly about the effects of ambient water pressure, which doubles in the first 33 feet of sea water.

If the intent of the question is to ask if one can breathe underwater through a garden hose used as a snorkel, the answer is "not deeper than a few feet". In fact, breathing through a snorkel deeper than about two feet is extraordinarily difficult. Your diaphragm simply isn't strong enough to displace the water at deeper depths.

One could use a hose like a garden hose with surface supplied air. The "snuba" systems used at some resorts use this approach. "Scuba", however, is defined as Self Contained Underwater Breathing Apparatus. It's a fair argument that any system which involves a surface gas supply is no longer "self contained".

Can you wear swimming goggles for snorkeling?

Snorkeling and diving masks include a place for the nose. This allows you to blow out and relieve the vacuum created by water pressure when going deeper. Swimming goggles should only be worn on the surface. Prolonged time spent underwater (5+ feet) can lead to tiny blood vessels in the eyes popping leaving your eyes VERY red for a few weeks. This also happens to divers who forget to breathe into their masks as they descend.

Actually higher pressure pushing against goggles does not create a vacuum, you would have to suck the air in the goggles through your eyes to extract air creating lower pressure, and thus a vacuum.

But on the surfaceI have used goggles snorkeling many times. It is tricky as your nose is in the water (with a mask, if you breathe in through your nose by mistake, nothing happens). I developed this technique when I would bring swim goggles to places like the Virgin Islands so when I was swimming "laps" I could see the interesting bottom. It was only a matter of adding a snorkel that made me realize that if you aren't going to snorkel much at all, goggles take alot less space in the suitcase than a mask. But if the purpose of the trip is to snorkel, bring a mask!

What is drift snorkeling?

Drift snorkeling refers to simply floating passively on the sea surface while using snorkeling gear to observe below. It differs from "active" snorkeling in that the snorkelers do not use fins to propel themselves along, unless they see something they want a closer look at.

This is a good technique in certain circumstances, such as when there is a current to move you along AND a nearby boat drifting along with you. Without the "rescue boat" nearby, it can put you in a difficult or even dangerous situation because you may be focused upon the world beneath the water and be unaware of how far you have gone or even where you are.

Can you snorkel wearing contact lenses?

AnswerAbsolutely. It's possible, though, as with any other physical activity, to lose a conatact. In the fifteen years I've been scuba diving and snorkeling, I've lost a lens only once, when a wave at the surface hit me squarely in the face. If you're worried, though, and depending on your vision, it's helpful to know that the refraction of water often allows someone with poor vision to see better underwater, so you may find you don't need the lenses as much.

Correction

Most of the time you can snorkel safely with contacts (barring the risk of losing them). However, in extreme cases (where you snorkel a lot, very deep, or both) you can interfere with gas exchange (nitrogen in this case) over the surface of the cornea, and in very extreme cases you can seriously damage the cornea as micro-bubbles form.

For most snorklers, this is a very unlikely problem. However, it shoud be noted that groups of pearl divers in the South Pacific actually got the bends while free-divig for pearls (90' dives, 4 minutes surface interval between dives, lots and lots of repetitiion).

As studies have not conclusively investigated gas exchange across the cornea, I would personally avoid diving with contacts. Note that it's easy and inexpensive to get almost any prescription lens sized for your mask.

Fine for surface snorkelingI have been snorkeling for decades (gave up diving) and on the surface, gas exchange is no more an issue than when standing on the shore.

The mask's water/glass/air interface provides a bit of magnification, so myopic people like me can snorkel ok without contacts, but I have found that wearing the contacts makes quite a difference in finding those well-camouflaged fish, especially if the reef is more than a couple meters down.

The advent of "disposable" contacts (it used to be $60 to replace one contact!) makes snorkeling with contacts stress-free. Just remember to bring your back-up glasses as snorkeling is a water activity and increases the odds of losing one.

What is swimmer using flippers and a mask?

a snorkeler. Or they could be an underwater hockey player.

How deep is the Olympic pool for high diving?

5 meters at sheffield and coventry

Last pool I dived into from a ten meter Olympic board was 16 feet deep.

According to FINA (the international swimming regulatory body), the minimum depth for pool which allows 10m platform diving is 5m.

Refer to the link below for the minimum dimensions (including depths) of pools which may be used for the various Olympic diving events.

Snorkel with period?

The presence of menstrual fluid (remember-you are not hemorrhaging-it is not "blood" per se but "menses"--the lining of the uterine wall that is red with blood cells from the interaction with your blood vessels) in the water will not attract sharks right away, although they may sense the presence of red blood cells in the water and come to investigate at night (which is when they tend to hunt anyway) long after you are already out of the water.

Depending on where you are in your cycle, the cold of the sea water at most snorkeling sites may be extremely uncomfortable for you, especially on the first or second day of your period. Remember when your mother told you to keep your hands out of cold water while you are having your period? She was right! Cold water temperatures contract the uterus and make you menstrate harder, creating cramps or nausea. I have a retroverted uterus, which made this situation a whole lot worse in the days before menopause! But, on the few times I tried it, some Extra Strength Tylenol allowed me to snorkel slowly anyway and enjoy my trip--although not as much as I usually do!

Be sure to always have tampons with you and put in a fresh one (or even two) well before you snorkel. The bathrooms at most snorkeling facilities or on most boats are not very clean or comfortable for changing purposes, and used tampons gum up the system on a "marine head" type toilet, creating extra problems for the boat and its crew. There are new products on the market such as "Instead" (functions much like a diaphragm) that will stop the external flow for several hours while you are on a snorkeling trip that might be a good substitute, although these are too new for me to have given it a try before menopause.

Make sure to have some fresh sanitary napkins with you for after your swim. Once again, I learned this lesson the hard way! Swimming wets the tampon(s) even more, and you may very well "leak" from the tampon(s) once you are out of the water! On one occasion in Bermuda, I did not realize this, and the guys on the boat had to follow around after me with a hose, washing off the deck once I got out of the water!! Fortunately, they had no idea it was me who was causing the problem, since there were a lot of other women on the trip with us!! They just assumed it was one "of the women" who was creating the mess on the deck!! <VBG> Embarrassing for me all the same!! If you are into the heavy phase of your period, go to the bathroom (or find a private spot) and just stick a napkin onto or under the loose nylon pocket of your suit. This just takes a few seconds and will make you feel more secure and comfortable.

Can you snorkel without being able to swim?

It is much easier to swim with fins on but the basics of swimming are necessary and a certain comfort with having your head under water for lengths of time is better. Trying to swim with your head under water but not so far that water gets in your snorkel, and just breathing through a snorkel for that matter takes some getting used to.

How do you clear your snorkel while scuba diving?

When you get to the suface with your head down take a breath off your regulator the take it out of your mouth. Put the snorkel mouth piece in your mouth and blow really hard.

Will water go up your nose when snorkeling?

NO, water will not go up your nose when your snorkeling. They make the snorkel a special way. You are very safe!!!!

AnswerActually the snorkel has nothing to do with the nose. Your nose is safely covered by the mask, so as long as your mask is not full of water, your nose stays nice and dry.

The only chance of water going up your nose is if your mask is leaky and water collects at the bottom of the mask, right where your nose is! That is why they emphasize you get a correct-fitting mask which is easily tested (in the shop) by pressing it on your face without using the strap, suck in a bit with your nose, and see if it stays on.

How do you breathe when snorkeling?

just breathe normally through your mouth just keep your head down or it will fill with water! swim on the surface and when you lift you head out of the water makesure that your snorkel has not filled with water before you try to breathe through it again!! have fun ---- I like to "sip" the air over my tongue. It seems to trap droplettes moer effectively. Nice not to aspirate :} Actually, this answer is incorrect. When snorkelling, you take a deep breath, dive down and as u reach the surface u blast the water in the snorkel out and repeat the process. If you are jus swimming on the surface it is not technically snorkelling, but some people like to call it skin diving to clarify. Or -- as you ascend, you can point the snorkel straight back so it's entirely vertical and puff a little air into it at depth. As you ascend, the air in the snorkel will expand, forcing water out. Just as you hit the surface, vigorously rotate your head foprwards and downwards, so the snorkel moves roughly 1890 degrees and the opening is now in the air, nearly vertical. Blast a little air out to remove the tiny amount of water remaining. Also, I think the act of "snorkelling" refers to whatever you choose to do from the time you leave the boat until the time you leave the water. So this would include phases when you're breathing on the surface, diving to depth, holding your breath underwater, clearing your snorkel, etc.

Why is it important to swim with partner while snorkeling?

It is good to have someone tell the search and rescue people where the body might be located. If it doesn't get to that extreme a partner might be able to help you stay alive ... if they know anything about reusing drowning people. Check out their skills in that area before you enlist them as your partner of you'll both run the peril of severe results.

How deep can you snorkel?

Snorkeling is only done at the surface. But if you hold your breath, you can dive down as deep as you want.
