Abstract
An apparatus for quantifying the position of a released arrow as it passes across the bow riser. A low power, electronics measurement unit attached onto or mounted internal to a bow in communication with a sensor detects a signal from an arrow shaft for the purposes of collecting data pertaining to arrow position. The electronics measurement unit provides a user configurable gain to control the variation and sensitivity of the collected data. The optical trigger mechanism used to stimulate the sensor does not require arrow shaft modification. Statistical parameters of the collected data are displayed on the bow and are used to determine and improve archery tackle performance.
