Abstract: A pocket sized, hand held electronic device for indicating the ball path for both the strike and spare ball. To indicate where the ball should start from the foul line, over which arrow it should pass and where it should strike the pin array. A plurality of indicators are provided at appropriate locations on the part of the device on which the static image of a standard bowling alley is provided. By pressing switch elements of a membrane switch arranged in the same configuration as the pattern of the real bowling pins, the user indicates which pins are still standing for the second ball, for a spare. With this input the device indicates the recommended ball path. Pressing a reset switch returns the display to the strike setting, to again indicate the ball path for the first ball of the next frame. The device can be adjusted to match the actual curve of the ball. One embodiment provides limited directions while a second embodiment provides more directions for the advanced bowler.
