Leaky Masks
Few things ruin a dive as quickly as a poorly-sealed mask. I had this problem the other day, and it disrupted my dive by being distracting and making me run through my air supply by constantly clearing it.
I started playing around with something that I think helps a little. Next time your mask is leaking water, instead of clearing it as usual, exhale a little stream of bubbles out your nose. Sometimes this will keep a small leak cleared by forcing the water out of the mask.
This approach managed to keep my mask clear without costing my air supply. I have to exhale anyway, so I just exhaled at the same usual rate but out of my nose instead of my mouth.
This may not work with all bad seals, but I imagine if the problem is at the bottom of your mask you may find it helps. It’s certainly better than repeatedly stopping to clear your mask.
