When the "heat" is on, there is no better call to challenge bucks in the area. The Challenger was designed to mimic the vocalizations bucks use in the rut to alert does or caution other bucks to their presence. Topped with a snort wheeze call, for a 2-in-1 call, creating the ultimate call for calling nearby bucks. The Challenger will have no problem rising to the top of your grunt call favorites.
