The original, patented Hoyt Dovetail system functions by self-centering the limb on the engagement surfaces of the limb itself. This means that the system will appear to be loose until the bow is strung. Once the bow is strung, the self-centering aspect of the system takes over. Every time the bow is shot, the limbs are forced to the precise center alignment dictated by the geometric position of the alignment dowels. This makes shimming limbs for pocket fit unnecessary. Note that other bow companies making an imitation Hoyt dovetail may not hold the necessary tolerances required for optimal system function. This will be the case will all current Hoyt recurve bows except for the Gamemaster II and Dorado.
