The arrow can include a compensator coupled to a shaft of the arrow and the compensator has diameter that is larger than a diameter of the shaft of the arrow. A thickness of the compensator, which is measured as the difference in the diameter of the compensator and the diameter of the shaft of the arrow, is configured to enable a user to aim the arrow with a bow that has been sighted for a standard arrow. ## Claims ### Claim 1 An apparatus for adding a payload capacity to an arrow while compensating for the extra weight added to the arrow, the arrow having a shaft, said apparatus comprising: an insert installable on a distal end of the shaft of the arrow, said insert comprising a chamber; a housing; means for removably securing the housing in the chamber of the insert; and at least one animal engagement member extending from said housing; wherein the diameter of the insert is greater than the diameter of the arrow, and wherein the diameter of the insert is chosen such that when the insert is rested upon an arrow rest of a bow, the insert raises the trajectory of the arrow sufficiently to compensate for the additional weight added to the bow by the insert, such that the arrow may be aimed as if no additional weight had been added while using a sight calibrated for use with an arrow without the insert installed, without making any adjustments to the aiming process due to the increased weight. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein said chamber comprises a chamber wall having a bore formed therein, wherein said bore is configured and dimensioned for removably receiving a first shear pin. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein said housing comprises a housing wall, wherein said bore extends through the housing wall. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the means for removably securing comprises a first bore formed in the arrow shaft and the housing, wherein said first bore is configured and dimensioned for removably receiving a first shear pin. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the means for removably securing the housing further comprises a second bore formed in the arrow shaft and the housing, wherein said second bore is configured and dimensioned for removably receiving a second shear pin. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein said arrow shaft comprises a longitudinal axis, wherein said first and second bores are perpendicular to said longitudinal axis of said arrow shaft. ### Claim 7 (depends on 1) The apparatus of claim 1, further comprising at least a second animal engagement member extending from the housing. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein said at least one animal engagement member comprises a hook. ### Claim 9 (depends on 1) The apparatus of claim 1, further comprising a chamber, wherein said chamber comprises a proximal end and a distal end, wherein said chamber comprises a pair of opposing sidewalls extending from the proximal end to the distal end of the chamber. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein said chamber further comprises a sloped surface at its proximal end, said sloped surface extending between the pair of opposing sidewalls. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein said housing comprises a radio transmitter. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein said housing comprises a GPS receiver. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein said housing comprises a battery. ### Claim 14 (depends on 1) The apparatus of claim 1 wherein the means for removably securing the housing comprises: at least one retaining member located on the housing; at least one retaining dimple located in the chamber; wherein the at least one retaining members can be snapped into the at least one retaining dimples, thus securing the housing to the chamber. ### Claim 15 (depends on 14) The apparatus of claim 14 wherein the chamber also comprises a first and second chamber sidewall; wherein the housing also comprises a first and second housing sidewall; wherein the at least one retaining members are located on the exterior of one or both of the first and second housing sidewalls; and wherein the at least one retaining dimples are located on the interior of one or both of the first and second chamber sidewalls.
