Today’s scuba masks are available in a variety of sizes, shapes, and styles. Apart from color and other non-functional design elements, different masks offer varying fields of vision and come with different lens designs. The style of mask you choose should depend primarily upon fit and function; here are some helpful hints for making a choice you’ll be pleased with.
Lens Styles
The most common styles of masks feature either three or four pane lenses. A 3-pane scuba mask features a single, solid front lens with additional windows on either side to enhance peripheral vision. Four pane masks are built more like glasses, with a separator at the bridge of the nose. Like three pane masks, they have side windows. Full face masks are available; but these are usually used by technical divers.
If you wear contact lenses or glasses, consider investing in a prescription scuba mask so that you can dive without wearing prescription lenses under your mask. The prescription portion of the mask is only in the front lens or lenses; the side windows are normally non-prescription. If your eyes are aging and you use reading glasses or bifocals, bifocal style gauge readers are a good investment.
Fit
A good fit is essential for comfort and for ensuring that you get a good seal so your mask does not leak. While inexpensive scuba masks are available, it is better to invest in one with a high grade silicone skirt. Hypoallergenic and flexible, these skirts help ensure that your mask conforms to your face properly.
In addition, choose a mask that has a nose pocket that is the right size and shape for your nose. Not only does the nose pocket cushion and protect you, it also helps to ensure that your mask stays fog free while you are diving, plus it helps to ensure you can purge your mask with ease. Whether you choose a mask with a purge valve or not is a matter of personal taste. Some divers like them, others stay away from them; because if they break during a dive, the entire mask will flood.
As you’re trying on different masks, take a look at the straps. Some have single straps, and others have double straps – the type of strap design you choose is a matter of personal comfort. Many divers like double straps because they offer extra stability, while some prefer the ease of a single strap. If you like a mask but you don’t like the straps that come with it, look for an after-market mask strap, and make sure you’re comfortable with the way it adjusts.
Trying on Scuba Masks
As you are trying out different masks, you can conduct a simple test to quickly eliminate masks that won’t work for you. First, place the mask over your face, ensuring it is in the right position, but leave the straps off. Next, inhale gently, through your nose, then start to breathe through your mouth as though diving. If the mask stays put without you needing to inhale through your nose again, or without having to push it back on with a hand, then you’ve found one that will probably be suitable. Manufacturers recommend keeping the mask on for about a minute to make sure you like the way it feels, and to ensure that the seal is suitable for your facial features.
After you remove the mask, look in the mirror. You shouldn’t be able to see a red mark on your face – if you do see lines, it means the mask was too tight and you should keep looking. If you’re having trouble finding one that fits right, ask for help from a dive shop employee or get a more experienced diver to go shopping with you. Take your time, and be sure to make a good decision – the right mask will help you enjoy your dives, while the wrong one will be nothing but trouble.
