The Aftershock just might be one of the most unique goose calls on the market. It is one of the easiest short reed style calls to learn on due to its deep natural tone and light air requirement. The Aftershock is the perfect call for hunters that are used to blowing a flute or have trouble getting deep on a short reed. It has mellow tone great for hunting over water or areas where volume is not needed but 100% goose is a must.
