The sight is programmable to alter the respective sight pin position(s) associated with one or more distance(s) to account for specific performance characteristics of a user's bow and/or arrow. ## Claims ### Claim 1 A sight for use in combination with an archery weapon comprising: a housing; a sight pin, wherein the position of the sight pin relative to the housing is adjustable; detection means for detecting a position of said sight pin relative to said housing; display means for providing an indication of a range to a selected target; and control means operable to receive an indication of the position of said sight pin from said detection means, and operable to cause an associated indication of the range to be displayed on said display means based on a detected difference in position of the indicated sight pin position and a stored association of a first sight pin position and a first range. ### Claim 2 (depends on 1) The sight of claim 1, wherein the position of said sight pin relative to said housing is adjusted via an adjustment means. ### Claim 3 (depends on 2) The sight of claim 2 wherein the adjustment means comprises a flexible cable adapted to engage a screw. ### Claim 4 (depends on 3) The sight of claim 3 further comprising a flexible cable holder and a knob. ### Claim 5 (depends on 1) The sight of claim 1, wherein the stored association is user-defined. ### Claim 6 (depends on 1) The sight of claim 1, wherein the position of said sight pin relative to said housing is continuously adjustable. ### Claim 7 (depends on 6) The sight of claim 6, wherein a control means includes a stored association of at least one sight pin position with a corresponding range, and wherein said control means is operable to cause said display means to provide an indication of a corresponding range for each position of said sight pin relative to the housing. ### Claim 8 (depends on 1) The sight of claim 1 consisting of a single sight pin. ### Claim 9 A programmable bow sight comprising: control means having a first stored association between a first position of an adjustable sighting element and a first range to a target; detecting means for detecting the position of the adjustable sighting element; and display means for indicating a range associated with a detected position of said sighting element, wherein said control means causes said display means to indicate the range associated with the detected position of said sighting element based on the first stored association between the first position of the sighting element and the first range. ### Claim 10 (depends on 9) The programmable bow sight of claim 9, wherein the detected position is substantially the first position, and wherein the range associated with the detected position is substantially the first range. ### Claim 11 (depends on 9) The programmable bow sight of claim 9, wherein the detected position is substantially different than the first position, and wherein the range associated with the detected position is determined based on a difference between the detected position and the first position. ### Claim 12 (depends on 9) The programmable bow sight of claim 9, wherein said sighting element is substantially continuously adjustable. ### Claim 13 (depends on 12) The programmable bow sight of claim 12, wherein said control means further comprises a second stored association between a second position of said sighting element and a second range. ### Claim 14 (depends on 12) The programmable bow sight of claim 12, wherein the detected position of said sighting element is detected via a linear position sensor operable with means for adjusting a position of said sighting element relative to said housing and said control means. ### Claim 15 (depends on 14) The programmable bow sight of claim 14, wherein said control means is operable to determine the detected position of said sighting element based on an output of said linear position sensor. ### Claim 16 (depends on 9) The programmable bow sight of claim 9, wherein said control means is programmable to at least one of disassociate the first position of said sighting element and the first range, and associate a second position of said sighting element with the first range. ### Claim 17 (depends on 9) The programmable bow sight of claim 9 consisting of a single sight element. ### Claim 18 (depends on 9) The programmable bow sight of claim 9 wherein the sighting element is adjusted by an adjustment means comprising a flexible cable adapted to engage a screw. ### Claim 19 (depends on 18) The programmable bow sight of claim 18 further comprising a flexible cable holder and a knob.
