<p>Apparatus for detecting, measuring and/or displaying differences from a desired ideal golf swing comprises (a) one or two permanent magnets (91, 92) in spaced recesses in one or more clubs (90), (b) a number of loops (71-74) in a planar detector array close to the notional or actual ball position (93) and (c) readout means for picking up the various signals created as the magnets cross straight line portions of the loops and conveying them to indications of swing angle, club face angle, club face tilt, impact zone at the club face, speed, acceleration, rake and so on. The magnitudes of speed, height sensitivity, and magnet strength permit such golf diagnostic equipment to be readily constructed and give usable displays of figures or (on a screen) outcome of the notional golf stroke.</p> |
