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 objective of using snorkel masks is to protect your eyes from water and to any other objects that may harm you as you dive. It is critical to choose what is best in the market since it’s an important item. Masks that are of top quality is something that feels right to your face, fits perfectly to it, does not let water to get and at the same time, lets you see the world underwater clearly.
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 – for any snorkel mask that you will buy, its ability to let you see underwater clearly is the most important aspect you should consider. Meaning, the formation and lens measurement will affect your decision on which one to buy. 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.
In single lens, it provides larger view since it doesn’t have frames that run across the bridge of your nose.
With a single lens, it’s impossible however to replace for prescription corrections.
On the other hand, if you are in need of prescription lenses replacement, then better opt for twin lens snorkel masks. You can easily fit it as part of the frame.
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 – you should not take this for granted as well and have to do quick research for internal volume prior to 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 a lot of people who actually prefer masks with lower volume as it’s more comfortable to wear.
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. Many snorkel masks don’t run at same angle since the face is scraped at the bottom. This improves the user’s lower field view while reducing the internal volume too. Once the mask angle is raked, the frame will then move back to cheek bones which makes it less of a challenge to look downward.
