Abstract: An arrow rest for use with an archery bow comprises a flexible planar member in which a dislodged arrow is gravitationally urged down repositioning edges toward the launch position. Upwardly extending arms prevent horizontal exit of a dislodged arrow and return a dislodged arrow to the repositioning edges for gravitational urging toward launch position. An enclosing arm connects the upwardly extending arms to prevent vertical exit of a dislodged arrow and to return a dislodged arrow to the repositioning edges for gravitational urging toward launch position. An embodiment provides for lateral insertion of an arrow through a flexible gap in the enclosing arm. An embodiment of a launch position provides a common axial centerline for a wide range of diameters of arrows.

Abstract: A bow angle tuner for aligning an arrow to an archery bow, for precise arrow flight, while the arrow is in the bow, by measurements or comparisons which integrate a minimum of five mechanical bow adjustments, and the diameter of the arrow. A planar member includes a groove, either angular or circular, on one face in which an arrow, of any commercially available diameter, is releaseably secured. One or more rulers, of suitable and equal length, are releaseably attached to, or integral to, the planar member and positioned in such a manner that the rulers form an included angle of less than one hundred eighty degrees and the included angle is bisected by the groove in the planar member and centers on the groove in the planar member.
