Golf tee insertion depth measurement and marking system

A golf tee insertion depth measurement tool for providing a gauge to facilitate marking a shaft of a golf tee to indicate a desired insertion depth that will provide an optimum height for a golf ball placed on the tee, which ball is to be struck by a club face having a height H1, the tool comprising:

• a base portion having:
• an upper edge;
• and
• a bottom surface that is spaced from the upper edge by a distance D;
• and
• an elongate stem portion connected to the base portion and extending upwardly from the upper edge of the base portion, the stem portion having a plurality of spaced-apart apertures extending through the stem portion, the stem portion extending to a height H2 above the upper edge of the base portion.

A golf tee insertion depth marking apparatus for marking a shaft of a golf tee to indicate a desired insertion depth that will provide an optimum height for a golf ball placed on the tee, which ball is to be struck by a club face having a height H1, the apparatus comprising:

• a marker tool comprising:
• a housing having at least a first surface and a second surface;
• a first bore extending from the first surface into the housing, the first bore having a diameter sufficient to receive the shaft of the golf tee when the shaft is inserted therein;
• a plurality of first windows disposed in the second surface of the housing, each of the first windows providing an opening into the first bore, each first window of sufficient size to receive a tip portion of a marking pen inserted therein, whereby the tip portion of the marking pen may make contact with and mark the shaft of the golf tee inserted into the first bore;
• a second bore extending from the first surface into the housing, the second bore having a diameter sufficient to receive the shaft of the golf tee when the shaft is inserted therein;
• and
• a plurality of second windows disposed in the second surface of the housing, each of the second windows providing an opening into the second bore, each second window of sufficient size to receive a tip portion of a marking pen inserted therein, whereby the tip portion of the marking pen may make contact with and mark the shaft of the golf tee inserted into the second bore;
• and
• a measurement tool comprising:
• a base portion having:
• an upper edge;
• and
• a bottom surface that is spaced from the upper edge by a distance D;
• and
• an elongate stem portion connected to the base portion and extending upwardly from the upper edge of the base portion, the stem portion having a plurality of spaced-apart apertures extending through the stem portion, the stem portion extending to a height H2 above the upper edge of the base portion.

A method of using a measurement tool and a marking tool to mark a shaft of a golf tee to indicate a desired insertion depth that will provide an optimum height above the ground for a golf ball placed on the golf tee, which ball is to be struck by a golf club head having a face, wherein the measurement tool comprises a base portion and an elongate stem portion extending from the base portion, wherein the stem portion has a plurality of spaced-apart apertures, and wherein the marking tool comprises a housing having a first surface, a second surface, a one bore extending from the first surface into the housing, and a plurality of windows disposed in the second surface of the housing that each provide an opening into the bore, the method comprising the steps of:

• (a) placing the base portion of the measurement tool on the ground with the stem portion extending upwardly;
• (b) placing the golf club head on the ground with the face of the golf club adjacent the measurement tool;
• (c) determining which one of the apertures in the stem portion of the measurement tool is closest to an upper edge of the face of the golf club;
• (d) placing the measurement tool adjacent the marking tool, with the apertures of the measurement tool aligned with the windows of the marking tool;
• (e) determining which one of the windows of the marking tool is aligned with the aperture determined in step (c);
• (f) inserting the golf tee into the bore of the marking tool;
• and
• (g) marking the shaft of the golf tee by inserting a tip portion of a marking pen into the window determined in step (e) and contacting the tip portion of the marking pen against the shaft of the golf tee.
