The ‘CORE’ is our newest goose call. It comes standard with our custom molded broke-in guts. The call is designed to be tuned to mimic interior Canada geese so it is a little higher pitched than the Life Sentence. The CORE is fun to blow, has a ton of range, a lot of volume, good crack on the top end and really good low end because of the broke-in guts. Pick it up and it’s sure to be your new favorite call!
