One of the most critical parts of a dive mask is the nose piece, and there are two types of nosepieces, full-face or half-face masks. Full face masks usually come with a nasal guard that fits around the mouth and nose and protects the wearer’s air passages. A half-face mask is designed to cover the bridge of the nose and the chin while giving the wearer the same protection as a full face mask. Both of these masks work by having a small slit in the front of the mask.
The best way to choose an RX dive mask is by comparing one of the several models available. One of the best ways to get useful information about this sort of mask is by asking at dive shops or doing some online research. Many sites on the internet will give you information about the different types of masks available and help you select a mask that works well for your diving needs. It is crucial to choose a mask that is comfortable to wear and fit appropriately so that you do not have problems with the mask during your dives.
