Box calls

Use a plastic bread sack to keep them as dry as possible, however,in humid climates, the humidity will eventually begin to affect the call.To dry them out, just leave them on the mantle of the fireplace, or in an upstairs room. Carefully clean and re-apply chalk. This works with any wood call.

Slate calls

Slate surfaces are also affected by humidity. The old saying about the surface is...if its black, put it back. If its gray, let it play. You can dry out a slate call with a lighter, but be very careful not to crack the slate.

Humidity affects the tone and quality of all striken calls. Some may sound better with a little humiity. Try your calls in different operating conditions, so you'll know which to use in what environment. This is one area of being able to operate multiple types of calls becomes very important.
