it protects you for water going into your nose
It was a bright green snorkel mask.
Mares, Cressi and technisub are all great brands.. When buying your mask and snorkel the most important factors you should however consider is Fit and Comfort
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.
It should be made out of plastic. ( I guarantee it ).
Snorkeler as in snorkel
Snorkel equipment is actually quite simple, with the three main pieces of equipment being a mask, snorkel, and fins. If you snorkel often, it is advisable to buy your own equipment. Using those offered by hotels or other companies is fine once in awhile, but frequent use could lead to an infection. Other times, the snorkel equipment just doesn't fit. To acquire the perfect feel and limit your risk of infection, read on for information on how to buy a mask, snorkel, and fins. When buying a snorkel mask, look for one that has a soft silicone skirt that goes around the mask's exterior. This material will conform to your face and ensure water does not reach your eyes. The fit of a snorkel mask is really all about how it can conform to the shape of your face. Also look at the nose pocket of the mask. The bottom of the nose pocket should extend past your nose so that the two aren't touching. If they are touching, you won't be able to properly exhale. The best snorkels have a flexible tube that connects the mouthpiece and the extended portion of the snorkel. This flexible tube will allow for optimal positioning while you are underwater. To reduce water entering the snorkel, look for one that has an enclosed end and reservoir below the mouthpiece. Also look to make sure the snorkel comes with an attached snorkel keeper. This is a flexible strap that goes around the mask to make sure you don't lose your snorkel. Finally, look for fins that are appropriate for the type of snorkeling you plan to do. If you will be in an area with minimal waves, short fins are best. Larger fins will help you propel through powerful waves and currents. Also consider whether you want full-footed fins. These type of fins are placed over bare feet. If you plan to wear shoes or booties in the water, look for a pair of open-heeled fins.
I just took my mask, snorkel and flippers halfway around the world for six weeks, about 10 planes. I put it in my checked bag, though I think I could have carried it on with no problem.
I don't know if snorkel gear can be rented at Hilton Head. I always take my own because often times the gear you rent will be wore out. Good snorkel gear isn't that expensive and it packs well into luggage. Take your own mask and snorkel at least, you will be glad you did. Rent fins would be OK.
The meaning of ABC in scuba diving is Mask, Fin and Snorkel. We can call them as main aparatus.
During the dive your nose will want to naturally breath in, or take in water so having the nose under the mask helps that NOT to happen. Also if you take on water inside your mask and your nose is not within it will be VERY difficult for you to empty the water. To empty water from your scuba mask at depth you simply pull it out from your face and breath out through your nose and this causes the water to pour out. How would you do this if your nose is not enclosed within the mask? And also so that water doesn't go up your nose. And mouth (it doesn't taste good).
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.
