Abstract: An adjustable holder for a hunter's tree stand provides support for various bow sizes. The holder may comprise: a mounting plate; a bow support arm pivotally attached to the mounting plate to be moveable in discrete increments; a locking plate being slidably mounted in relation to the support arm; a biasing member to bias the locking plate relative to the bow support arm and releasably engage slots located in the mounting plate to provide the incremental movement; and upper and lower bow retaining members, To provide vertical adjustability, an extendable arm is provided and telescopes outward from the bow support aim, and upon which is mounted the upper bow retaining member. Further adjustability is accomplished with the lower bow support member, which may comprise a shaft with a knob disposed upon one end, being pivotally secured to a crank arm that is then pivotally secured to the bow support aim.
