Abstract
A split-buss-cable single-cam compound archery bow substantially reduces torque exerted on the bow by the buss cable as the bow is drawn. An adjustable-width and adjustable-position splitter holds split buss cable ends in a substantially parallel spaced-apart configuration. The splitter is adapted to enable attachment at varying positions along the split buss cable and to enable adjustment of the splitter distance. The splitter may be positioned so as to substantially eliminate interference between the split buss cable and an archer's arm as the bow is drawn and released.

- a split buss cable, the split buss cable having a first end and a second end, the first end being secured to the cam assembly, the second end being bifurcated into first and second split buss cable ends, the first and second split buss cable ends being secured at the first bow limb tip at opposing sides thereof;
- and
- a buss cable splitter, the splitter including a substantially rigid member secured to the first and second split buss cable ends so as to hold the first and second split buss cable ends in a spaced-apart configuration separated by a splitter distance,
- the cam assembly being adapted for letting out the draw cable as the bow is drawn, for letting out the let-out/take-up cable as the bow is drawn, and taking up the first end of the split buss cable as the bow is drawn,
- the splitter being adapted for enabling removing and re-securing the splitter at varying points along the length of the first and second split buss cable ends.
