Now there's a new thought . . .
I mostly rely on one call, a box type called "double thunder" I never thought of taking more than one call with me for a greater variety of sound. May have to try that. I mean I can make a lot of different sounds on the double thunder, but a smaller or larger call would have a different pitch and a slat call would have a different tone. May have to invest in a few more calls.
Live well, be safe
