I posted this along time ago . . . no answer.
"How", water-proof is the PM3?
Is it water proof enough that it can be used in a light rain, light snow or even in a fog?
At what point must a PM3 be broken down because of weather.
What about snow-flakes that land on the face of a PM3, then melt? Is this too much water?
i have used it in light rain as you said, with no problems
