The Ulitmate Big Buck Kit includes: Pack Rack, EZ Grunter, Windseeker II and Ultimate Whitetaill XIII. Pack Rack: Pull the two pieces apart. Hit them together and twist in a clock-wise and counter-clock-wise motion. Use your hands to cover and uncover the sound chambers as well as grip each piece firmly or loosely to vary the volume and give realism to your rattling sequence. Now, set the call down, grap your gun or bow and get ready. EZ Grunter: This is the original EZ Grunter, the call that started it all... one of the first Knight & Hale calls. The EZ Grunter's hose is virtually the same size as a deer's windpipe making it easy for you to produce the accurate tone and guttural sound of big bucks. You can use this call as a basic "grunter" as it is easy for you to produce most of a deer's "contact" sounds. Windseeker II: Never let the wind cost you that trophy of a lifetime. Windseeker II from Knight and Hale is an essential item to always keeping the wind in your favor. The fine, lightweight powder will detect even the slightest wind current. Knight & Hale Ulitmate Whitetail XIII Buck Fever: Settled in, bow on the hanger. Frosty breath rises above your facemask as the sky goes from black to grey and the stars disappear.
