The Flextone All-N-One Deer Call developed by Tom Wiley features a patented combination of hard and soft parts that mimic the rigid voice box and soft, flexible neck and mouth tissues of a deer. This design produces an enhanced control of volume and tone, giving you a fuller range of vocalizations and a more natural sound. The All-N-One Deer Call also features buttons that show the user where to squeeze the call, (F) for fawn, (D) for doe, (YB) for young buck or just blow without squeezing for a mature buck. The opposite end also has a volume button for volume control. Now you have the flexibility to produce a full range of vocalizations with one deer call. The Flextone All-N-One Deer Call will, with just the squeeze of a button, accurately produce a fawn bleat or distress, a doe bleat or grunt, as well as a young buck or a mature buck grunt. Not only will you appreciate the natural sounds this call makes, but also the sounds it does not make if accidentally coming in contact with your gun or bow.
