ABSTRACT:
A hand held device for drawing and firing a bow that includes a housing containing a latch for engaging the bowstring and a balanced beam for holding the latch in a locked condition. A trigger mechanism is adapted to unbalance the beam when it is depressed a first distance. A spring loaded arm is adapted to be coupled to the trigger by a sear in a loaded condition so that when the trigger is depressed a distance less than the first distance the arm is uncoupled allowing the arm to strike the beam and thus fire the bow at a reduced trigger pressure.
