Abstract

An archery projectile facility comprises an elongated body. The elongated body includes at least one accelerometer. The at least one accelerometer is operable to generate three-dimensional acceleration information. The archery projectile facility comprises a body processor. The body processor is operably connected to the at least one accelerometer. The body processor is adapted to process the three-dimensional acceleration information to generate sampled information. The archery projectile facility comprises a transmitter. The transmitter is operably connected to the body processor to broadcast the sampled information. The archery projectile facility comprises a receiver. The receiver includes a receiver processor. The receiver processor is adapted to generate resulting information based on the sampled information. The resulting information is based on a determination of a stabilization point.
