[underwater exhalation]
At some point in your diving career your mask is going to get knocked off your face.
Maybe you're following somebody too closely and you get kicked in the face...that's your fault!
or your mask strap breaks... things just happen...
and of course your mask may fog and water may leak in.
In this video we're going to demonstrate how to remove and replace your mask.
To clear the fog from the inside of your mask, break the seal on the top and let water enter.
To clear the mask, apply pressure to the top, relieve pressure from the bottom
and as you roll your head back exhale through your nose.
Notice how when the water comes in contact with the lens it clears the fog.
We do this skill so we can see when we are underwater.
Make sure when you exhale you leave a space between the bottom of your nose and the inside of the nose pocket.
Break the seal,
let water enter the mask,
apply pressure to the top, relieve pressure from the bottom
and as you exhale, roll your head back.
When we remove a mask,
first you flood it and then pull it away from your face.
To replace the mask, you can either put the mask against your face and form a seal and then put the strap on,
or you can put the strap on
and then put the mask on your face.
If you're wearing a hood, make sure that the mask only comes in contact with your face.
If the mask goes from your face and over your hood it will leak where the two meet.
Apply pressure to the top, relieve pressure from the bottom, as you roll your head back exhale through your nose.
That's how you clear a mask.
