Re: Good Mask De-fogger?

Cliff Coggin wrote

Here in UK waters I get condensation inside my mask for much of the year,
but because glass and silicone are clean the water runs down without
obscuring vision. It's comparable to rain on a car windscreen: if the
glass is clean the rain will run off as a clear film, if the glass is
dirty the rain forms spots that can't be seen through.

Your windscreens, and mask lenses, must be made of a different kind of glass
from ours. Rain does not run off our windscreens here unless driven by the
force of wind. Even with RainEx, which is a coating designed to facilitate
that, it does not run off until your speed is in excess of about 40 miles
per hour.

We both have our own solutions to the problem. I prefer to clean the mask
once a year than to adapt my diving technique.

I suspect that you've already adapted. If not, I'm a bit surprised that you
would deliberately choose to continue a poor technique and particularly
surprised that you would recommend the same to others. Recreational diving
is a highly individual sport, but there are some generally accepted best
practicies. Not breathing through your nose is one of them.
