To all who have Enticer Aluminum Calls. I started putting Aluminum Call instruction. in each call today. Condition 3 different places on the call, as the call will play the same 360 & 1 inch in from the edge. You will get 3 different sounds , one place with green scotch brite for hi pitch, one place with 400 grit for sharp pitch & one place with the gray stone for deep raspy. All 3 are in the call pack. Hope this helps! thanks Al Holbert
