Abstract: The present invention provides a “third-axis” leveling block for use with an archery sight. The third-axis leveling block holds an archery sighting device (e.g., a scope or a pin sight) as know in the art. The leveling block adjusts the position of the sight in two axes by means of cams. One of the cams adjusts the sighting device to the archer's preferred cant. The other cam adjusts the angle of the sighting device with respect to the bow to keep the archer's cant consistent when the bow is raised or lowered for shooting at targets at any elevation, above, below, or on the same level as the archer.
