Woodhaven Turkey Call Mouth Red Vyper Model: WH071 The Red Vyper is a 3 reed call with our famous red latex as a top reed, clear latex as a middle reed, and black latex as a bottom reed. A classic "V" cut call with the tips of the side wings nipped to create our "Vyper" cut. The yelps have been sweetened ever so slightly while still producing the hard cutts, cackles and clucks'n purrs.
