I would like to buy a snorkel and mask, but dont no where to start, i would like a good one that wont leak,

The best mask for you is the one that’s most comfortable to wear. Everybody’s face is a different shape, so you should try on several masks to see which is most comfortable. A dive shop of any description will be your best bet for finding a wide selection.

To check whether the mask seals against your face, place it over your eyes and nose WITHOUT hooking the strap over your head, and inhale gently through your nose–if the mask sucks onto your face and prevents you from inhaling any further, it’s a good fit. You’ll need to clean the mask lens with white toothpaste before using it for the first time.

Snorkel selection is usually fairly straightforward. So long as it’s wide enough that you can breathe through it easily, it should be fine for you. For an average adult, the snorkel should be at least 20-25 mm (3/4 to 1") in diameter. Whatever model you buy, you’ll need to take deeper breaths than normal, to compensate for the extra ‘dead air’ space of the snorkel tube.

NB Most top-mounted Snorkel ’splashguards/wave protectors’ etc. don’t work all that well, and if you skindive down under the water, the snorkel will flood regardless–so the extra bux for these attachments aren’t really worth it. If you have a lungful of air, a sharp ‘blast’ exhalation will clear any snorkel quite effectively.

Here’s a few specifics to look for:

Mask:
–Low volume (two-lens masks have a lower volume than single-lens masks)
–Tempered glass faceplate, not polycarbonate (glass stays clearer, and doesn’t scratch as easily)
–Silicone skirt, not rubber (silicone is softer, and less allergenic)

Snorkel:
–Silicone mouthpiece
–Drain valve (makes snorkel clearing easier)
–Simple, robust mask-strap attachment clip

Im planning a trip and want to scuba and/or snorkel. I do have my blood sugar under control.

There is nobody that will stop you from snorkeling, and you should be safe enough as long as you are Snorkeling with a buddy.

If you are insulin-dependent, the answer is generally no to SCUBA because of the increased risk of sudden loss of consciousness. In years past the answer was an unequivocable no, diabetes was considered an absolute contraindication to SCUBA training. Today, diabetic individuals that meet certain criteria MIGHT be allowed to SCUBA dive if they follow specific procedures. If you aren’t already certified, you will also need to have a medical exam and obtain a physician’s approval to participate in diving in accordance with that dive training agency’s standards.

I want to check out Wakiki, but I don’t need to stay there. I’ll have a rental car so I can drive around…assuming parking isn’t a hassle. I’m looking more for a relaxing vacation than feeling like I’m right back in the middle of a major city. I found a great deal on a vacation rental near the Kohala Mandarin, but I don’t know how great the beach is there. I love to snorkel, but other than Hanauma Bay and Shark’s Cove, no one seems to mention other good snorkeling areas. Lanikai looks nice in the pictures, but how about the snorkeling there? As you can tell, I’m doing last minute vacation planning!

Since you don’t want to stay in Waikiki, you’re definitely going to have to get a rental. Lanikai is a great place to get a rental. Kailua Beach Park near Lanikai is a very nice beach. You can Snorkel there, but you may not see much. The reason Shark’s Cove and Hanauma Bay are such ideal places for snorkeling is because they are closed off from the ocean. If it’s raining a lot (like it is right now) the runoff from the mountains tends to make the water brown and murky which makes it hard to see things when you are snorkeling. If you are coming anytime soon, expect a lot of rain. It’s been raining quite a lot here in the last month and may continue. Also in some places the coral reefs may be quite a ways off shore, which also makes it difficult. Other than these two snorkeling places (Hanauma Bay and Shark’s Cove) it may be difficult to find a spot. It may be a long drive from Lanikai to Honolulu (Waikiki), depending on what time you plan on driving. If it’s during any time of rush hour it’ll take you at least 1.5 hours to get to the other side. If you are going to Waikiki you can park in the Honolulu Zoo parking lot on the corner of Kapahulu Ave. and Kalakaua Ave. It’s metered but cheap and there are plenty of spaces. Hope this helps a little.

I’m shopping for inexpensive eye wear and a snorkel (fins to be rented on site). Can I just get pool-style goggles instead of the bulky mask? Is it that important to have my nose covered?

If you just stay on (or not far below) the surface, you could get by with goggles. However, I think you may have problems with leaks if you attach a relatively heavy & bulky snorkel to the swim goggles. Swim goggles seal over a relatively small area compared to a dive mask, and part of the sealing mechanism is the tightness of the strap. A well-fitting dive mask will create a seal pretty much regardless of the strap tightness, and the strap is there mostly just to keep the mask in place.

When it comes to breathing, as long as you can focus on breathing exclusively through your mouth you shouldn’t inhale water through your nose. If you’re not used to breathing through a Snorkel or regulator, though, you could have a tendency to inhale some water wearing goggles. With some practice this probably wouldn’t be the main reason you would choose a mask over goggles.

Where a dive mask is absolutely necessary instead of goggles is if you plan to hold your breath and dive to any significant depth below the surface. I’m afraid I don’t know what that exact depth is, but 20 or 30 feet seems like a reasonable number to guess at. Both dive masks and goggles allow you to see better underwater by creating an air space around your eyes which allow your eyes to focus (without a mask everything appears blurry underwater). Air, like any gas, is compressible meaning as you apply pressure to it it will compress into a smaller volume. As you dive under water, the weight of the water above you applies pressure to air spaces in and around your body, which includes your goggles and mask. (As an aside, this is why you feel pressure/pain in your ears if you dive deep enough underwater since your middle ear contains an air space.) As the air around your eyes compresses it takes up less volume and since nature abhors a vacuum something else must give to try to replace that volume…which ends up being the soft tissues around and in your eyes. The result is what we call a "mask squeeze". Here is an image of a classic example of a mask squeeze: http://www.bsac14.org.uk/photo/masksq2w.jpg . While it looks terrible, it is usually a minor injury and will clear up on its own like any bruise. There is no permanent damage to the eye as long as the redness is limited to the whites of the eyes and does not affect the irises (colored portion).

The reason that a nose pocket exists on a dive mask is pretty much just so that the air space inside the mask can be equalized with the water pressure outside the mask. This is done by exhaling a little air into the mask through the nose. Equalizing the pressure is what prevents a mask squeeze. Since swim goggles have no nose pocket, there is no way to equalize the pressure inside the goggles and so a mask squeeze cannot be prevented.

Anyway, even if you don’t intend to do any significant breath-hold diving, I think you will probably be better off with a well-fitting dive mask instead of goggles because of the leak risk. The whole purpose of snorkeling is to see what’s below you, and if your goggles should leak all the time you won’t have much fun.

Good luck with whatever your choose!

Some friends and I are traveling to Siesta Key, Florida in a few weeks and wanna go snorkeling. Any suggestions?

Well, the best shallow-water snorkeling on the Gulf Coast is on Siesta Key at a place called Point-Of-Rocks.

While 99 percent of the beaches in Florida are pure sand and shell, this spot has an outcropping of flat limestone rock that covers several acres of shallow water. Fish congregate here to feed, which makes for some very interesting Snorkeling. The water here is usually exceptionally clear and calm, and crowds are light.

Good luck, and the link below is to a webpage about Florida beaches and about halfway down the page is an article titled: "Best Snorkeling Beach - Crescent Beach, Siesta Key" with all the info you need…

I would like to try how to Snorkel but not sure if it is allowed if I do not know how to swim. Is it possible to try it even if I do not know how to swim?

You could do snorkeling and not know how too swim. All you need is too make sure you have a life jacket and some fins and just keep a steady kick behind you.
Have fun!

The human lungs can function satisfactory up to a limit where the pressure difference between the outside and inside of the lungs is one-twentieth of an atmosphere, if a diver uses a snorkel for breathing, how far below the water can she swim? Assume the diver is in salt water whose density is 1025kg/m^3.

it all depends on the Persons Lung Capacity
but as u get deeper under water the preasure from the water on your lungs causes ur lungs to become smaller and also compresses the air that is in ur lungs so the deeper u go the less Oxygen u will have in ur lungs

in Salt water the Pressure is alot Greater as U get deeper compared to when you in Fresh Water

also considering that when you use a Snorkel you are also not taking in a full breath of air as there is still a remainder of carbon dioxide in the snorkel Tube itself so it would actually be better to take a proper breath than to breath through a Snorkel

P.s Snorkels were Made for Surface Diving
dont think i was much Help Just spilling out the Info i Know
