This excessive forward hip position is preferable immediately prior to striking the ball and corresponds to the fore-strike position signal. The visual and audio response unit, located adjacent the tee platform, visually indicates to the golfer when his or her hips exceed the forward optimal position, and the rearward optimal position. These are negative feedback signals.

Abstract: Presented is a golf tee device having ground anchoring prongs to stabilize the tee upon impact with a club head and keep the tee from "popping" out of the ground and traveling haphazardly. Also, the tee incorporates a circular non-adjustable base feature that limits the depth to which the tee can be inserted into the ground, thereby adjusting the elevation of the golf tee, and thus providing a platform for the golf ball that is the proper elevation to meet the needs of a particular golfer. Further, the base feature also aligns the tee in a perpendicular position relative to the ground. Incorporation of spine supporting radii above and below the base feature serve to significantly increase the strength and resiliency of the device.
