The BGC Canada Hammer is one of the world’s most popular polycarbonate Canada goose calls because it super easy to use and produces the full range of typical goose sounds required for hunting. From soft moans and clucks to swing them in a little closer to up high with snappy hail calls to get their attention. Each call is fully tested and tuned by the exclusive BGC Pro Staff Tuners who modify the calls as needed to make certain they produce the full range of goose sounds. The insert features Quick Tune Guts and double O-rings help insure an airtight seal between the barrel and insert. All of these features add to the overall quality and style of this legendary goose call.
