I just finished with my pool dives and fixing to go to the open water. I am having a problem with the mask clearing. I guess I breath through my nose more than I thought but after swimming around under water for a while I finally choked my way through it. Any tips on learning to breath just through my mouth so I can get past this?
Thanks

Practice breathing from your snorkel or regulator with your face in the water without a mask on. You can pinch your nose if you need to, then let go and see if you can get comfortable breathing with your face in the water and no mask. Take your time and practice this until it does not bother you any longer. Then try the mask again.
