Features the Rack Blaster™ Grunt Call, the Snort Wheezer and the new Pack Rack™ Rattling System. The Rack Blaster produces all deer sounds with volume and realism that blows away other calls. The revolutionary Blasting Chamber® barrel is the key component. By chambering the air flow, then focusing it into a newly designed reed and tone board, the Rack Blaster is able to produce maximum volume and super-realistic sounds. Social grunts, tending grunts, aggravated and even growling grunts are made by exhaling into the chamber, while lusty estrous doe bleats and lost contact bleats are readily available by simply inhaling on the call. The semiflexible construction material and the ergonomic shape also contribute to the natural sound and allow for a multitude of sound manipulations and inflections. Sound Baffle technology gives Knight & Hale's Snort Wheezer added realism. Blow in the mouthpiece and the baffles do the work to make the meanest, maddest snort wheezes ever. Elicit territorial and dominance infringement responses from dominant bucks add realism to dominant rattling sequences and arouse the curiosity of subdominant bucks. The Pack Rack produces sounds of two bucks fighting.
