Snorkeling mask squirting issue

[Dom Perignon]

Hello,

I snorkle a lot and when I go back to the surface the air expels too fast, which sometimes breaks the seal right around my nose, causing sea water to shoot into my eyes. For most people that would not be a big deal, but in my case any sea water in my eyes will ruin the next 10 min (painful + blinking non stop = I miss the show).

Holding the mask as I go up does help, but it's not practical since my right hand is busy holding my camera, and the left one is, on occasion, holding my diving lamp. (Yes, I do enjoy night snorkeling, and always carry my cam).

I've been wondering if a low volume mask would reduce this problem. The thinking would be that lens air in the mask would end up reducing the air that gets expelled on rapid ascent.

Many years ago, masks with purge valves were popular. I don't know if they are still around.

They are indeed still around, made by diving equipment manufacturers such as the French Sommap company, who still cater for people who prefer classic designs:

Dom,

A couple of comments on this situation.

--First, the masks David Wilson discussed above are available, and will vent that air as you ascend. So that may be a good solution for you.

--However, I think that the mask you are currently using does not fit well too. The check is to put the mask on without the strap, and see whether if you inhale through your nose it will stay in place. If yes, and you can keep it on your face for over a minute, it fits. If it tends to break seal within that minute, you have a poorly-fitting mask.

--Finally, some free divers on their ascent pull that air back into their airway, rather than letting it vent. But this takes quite a bit of breath-control and practice.

another possibility is that you are wearing your mask too tight leading to a poor seal.
