Silicone masks, on the other hand, will last the user upwards of ten years, if cared for properly. Silicone mask skirts will always fit water trigger sprayer better, and give a better seal than other materials. This is because silicone has more elasticity, and can withstand repeated use in any type of water conditions. Silicone mask skirts come in two colors, clear and black, with the choice being a matter of personal preference. Clear skirts will allow more light to enter the mask, and give a brighter view of the environment. Black skirted masks, however, are very popular with photographers who prefer not to have any extraneous light entering their camera’s viewfinder. How should a mask fit? This is a question that has lots of answers.
First, try the mask on without the strap. Place the mask on your face and inhale through your nose very lightly. You should feel an even seal around the perimeter of the mask, with no air leaking through the mask at any point. Be especially cautious of the areas next to your eyes and under your nose, where lots of folks have some little lines or creases that can prevent a mask from sealing properly. Once you’re satisfied the mask fit without the strap, go ahead and place the mask on with the strap. Is there any discomfort……do you feel any air leaking when you try to inhale?Let’s talk about styles now. There a lots of different styles on the market today….single lens designs, twin lens, three lens and even four lens designs. As you move up in the number of lenses, the internal volume of the mask (the amount of air space inside the mask) tends to increase. This has both advantages and disadvantages. The advantage is that you will get better peripheral vision from a multi-window mask. The downside is that if the mask leaks somewhat it requires more effort to clear the water out of the mask. A great feature for snorkelers is a purge valve mask.
This type of mask has a small one-way valve that will allow the wearer to purge or remove the water from the mask without lifting the face from the water. All that is required is to hold the entire mask firmly against your face, and blow through your nose, keeping the purge valve at the lowest point of ther mask. This design saves energy and allows the wearer to keep their face in the water. In it’s most basic form, a snorkel is nothing more than a tube that allows you to breathe with your face underwater. The things to look for in a snorkel are a large diameter tube, allowing air to pass freely through the snorkel, and some type of purge valve system, which lets you use the force of gravity to help you move water down through the snorkel, rather than up against the force of gravity. The purge valve on better snorkels operates the same way as those on masks…..keep the snorkel bottom in the water, and blow forcefully to move the water through the purge valve, take a cautious breath, and you’re back to snorkeling!
Snorkels cannot be more than about 17 inches long, because your lungs do not have the strength to fully move against the water pressure. Some snorkels are curved to fit the side of your head better, making the snorkel less resistant to water, causing less drag. Other models have “dry tops” on them, meaning they have special one-way valves that will close off the top of the snorkel when the user dips their head under water or if a wave comes over the top of the user’s head. These valves work great for those that have had a less than desirable previous experience, or for those that can’t purge their snorkel completely of water when it fills. The best snorkels have special mouthpieces designed by an orthodontist, to alleviate the jaw and mouth discomfort some folks have when snorkeling for extended periods. Like masks and snorkels there are lots of different fins on the market today. Some fins are better utilized for Scuba Diving, rather than snorkeling. There are really two types of fins used, and these are full-foot or adjustable heel models. Again, each has it’s own advantages. For example, the full-foot fins, which are designed to be worn barefoot, are better for travel, as they weigh less, and are generally shorter and narrower than the adjustable heel style.
