Knight & Hale Da&rsquo; Bone Deer Grunt Call Looks like an antler, sounds like a buck and offers completely silent carry in the woods Exhale-style call produces extremely lifelike buck vocalizations with minimal effort and unmatched volume Delivers soft sounds for close calls as well as loud, booming calls that get bucks attention from afar Made from a soft, pliable material that wont clang against metal or freeze up during winter Ideal for long-range or windy-day calling situations when most other grunt tubes fail to carry enough sound
