A full face snorkel mask is an integral item of your snorkel gear. Through this, you can see what’s beneath the sea in full view. The purpose of snorkel masks are to provide protection to the eyes from any object that could harm you when you dive and also, to the water itself. Because of the reason that a face mask isn’t cheap, you have to be sure that you’re making the right selection. Top quality masks should be the one that fits perfectly in your face, feels just right, does not let water to get in and also, let you see clearly the world underwater.
With regards to buying a full face snorkel mask, there are actually a number of points that you have to be aware of such as:
Number 1. Lenses – among the integral elements that you have to be aware of when buying a snorkel mask is its capability of letting you see underwater. For this reason, you have to base your decision as well on the formation and measurement of lens. You may purchase multiple, twin or single lens configuration however, you must not take for granted that there are other options you can have such as the special coating, glass specifications and shape of lens.
Single lens can make the more open as they don’t have frames running across the bridge of your nose.
With a single lens, it’s impossible however to replace for prescription corrections.
In relation to twin lens snorkel masks, it is compatible with a prescription lenses replacement. Due to the reason that part of the frame is removable, it can be easily fitted in.
Multiple lens on the other hand have window panel for each side of mask in order to make it brighter and more comfortable.
Number 2. Internal volume – like the lenses, the mask’s internal volume plays an important role too when buying one. The volume is your confirmed airspace that’s made once the mask is sealed to your face. Internal volume is subjected to compression when the diver dives in the water. There are so many people who do prefer masks that have lower volume simply because of the reason that it is more comfortable.
Number 3. Mask angle – a lot of people don’t notice it but, angle of the mask is vital aspect of the full face snorkel mask too. Because our face is scraped at the bottom, different snorkel masks have different angulations. This is advantageous as it helps in reducing internal mask volume while improving the lower field view. As soon as the mask angle is raked, the frame moves back to the cheek bones and for that, looking downward is a lot easier.
