Wooden duck calls scream tradition, with their classic looks, their smell, their entire being. Gaston wooden calls are no different, hand turned one at a time, they are second to none! Gaston Custom Field Models have everything you want in a call. Great top end to reach those high ducks and plenty of volume to hunt open water or large field situations as well as that nasty, raspy, low end needed to finish birds in the hole. Cocobola. Single Reed.
