Flextone All-in-one Boned Up Deer Call looks as fierce as it grunts. Its flexible design is the reason this grunt call can create such realistic sounds. The call easily bends and twists for natural inflection – just like the soft tissue in deer's mouths and throats. Amateur callers will appreciate the user-friendly buttons; simply press to switch between compelling buck, young buck, doe and fawn sounds. The volume button offers further control for softer sounds. Advanced callers know the trouble disassembly and O-rings can create, but these modern upgrades paired with the call's impressive versatility will turn what could have been a tragic hunt into a triumphant one. There are people who just talk about getting things done. Then there are people who see opportunity, roll up their sleeves and do it. Flextone developed at the hands of doers who weren't satisfied with game calls on the market and decided to make their own. The calls' designs use a soft, flexible body to mimic throat tissue, while a hard reed plays the role of vocal box.
