I'm not a rain hunter, but I do get out in light mist and also when the grass is wet. I would like to get a rain cover instead of keeping a produce bag handy for such times 
I'm thinking of getting the Fisher F5 cover, but wonder about the holes in it for the knob shafts. It seems like water may still get into the detector, even with the cover, unless the pots are sealed mil spec units or some such thing. Don't mind spending the money, but if my plastic bag protects the unit better than the factory cover, I will keep using it.
Any feedback appreciated!
