The device includes a rebound board, and a precision tether adjuster having first strip of hook-and-loop fastening material attached to the rebound board, and a tether having a first end attached to a ball and a second end attached to a second, mating strip of hook-and-loop fastening material. The excess length of the tether is wrapped around the second strip, which is mated horizontally across the first strip at the appropriate vertical level for the user.
