Abstract:
In one aspect, a method of determining an instantaneous speed of an arrow, includes determining a time-of-flight of the arrow; determining a distance between a location from which the arrow is loosed and a location of a target-face; providing, with an apparatus included in the arrow, data from at least a portion of a free flight of the arrow; and determining the instantaneous speed of the arrow for at least one point of the free-flight by employing each of: a) the time-of-flight; b) the distance; and c) at least some of the data provided by the apparatus.
