Nuke 'em! Educated last season, call-shy birds react recklessly to this great finishing call to put them right into your decoys. With Brad's "VFR" Construction - Volume Flow Reduction (insert is constructed in a manner to reduce the escaping air, which results in more back pressure and better call control). Acrylic, double-reed construction, finessing call, great finishing call for that final "whisper in the ear" seduction into the "VFR" Construction. Better call control, easy to blow, real duck sound, soft beginning/pleading sounds.
