How to Use a Scuba Mask

There's three different styles of masks that we have here. There's some that have actually a split lens. So this is the split lens style, where the two lenses are actually separated. There's some that have a split lens with side window. This is the full face with the side window. On the mask. And then there's also another mask called the frame less mask, which really, there is no frame to this, there's no hard plastic frame like the one right below. And this mask is called the frame less mask, there's one solid piece of glass and then there is no frame on this. It's actually just silicone. Now the way to check to see whether a mask seals on your face, is to actually put it up to your face, take your glasses off, and. You want to breathe in slightly through your nose, and that mask should stay on your face when you do that.
