A combination golf tee and brush includes a cup-like top portion extending to a spike-like bottom portion. The top portion is configured as an arcuate, cup-like recess or cradle to nest a golf ball thereon. The bottom portion has an elongated shaft and a bottom tip that has an elongated edge. The tee brush has a series of mounting holes in which are mounted at least one group of flexible bristles or bristle portions. The bristles may include two laterally opposed groups of bristles or fibers that extend generally laterally from the shaft and are positioned closer to the top portion than the bottom tip.

An apparatus for fixing golf tees (6) by means of a band (2) which can be rolled up and unrolled and which is arranged together with the rolling and unrolling device in a housing (1) and can be fixed to the at least one golf tee (6), wherein the golf tee (6) has a tee shaft (7) for inserting into the ground and a plateau arranged thereon for a golf ball, wherein the band (2) has openings (3) which are arranged spaced apart in the longitudinal direction (4) of the band, are visible and accessible when the band (2) is unrolled and which penetrate the band (2) and into each of which a tee shaft (7) of golf tees (6) can be frictionally inserted.

To communicate with a magnetometer (82) within a golf ball (20) used in a golf facility, an electromagnetic coil (30) is configured to supply pulsed signals to the magnetometer. A plurality of coils (30) are provided at different locations around the golf facility, and the pulsed signals are preferably coded so that the location of the golf ball is known.

A multi-purpose golf tool includes a golf tee platform arranged on a golf tool body, the golf tee platform configured to receive a golf ball balanced thereon, a first prong extending from the golf tool body opposite the golf tee platform, a second prong extending from the golf tool body opposite the golf tee platform, a curved depression extending perpendicular to the length and formed by the golf tool body and a portion of the first prong and second prong, and a first rounded gap between the first prong and the second prong. The first prong has a first ridge extending perpendicular to the length and abutting the curved depression. The second prong has a second ridge extending perpendicular to the length and abutting the curved depression.

A golf tee may comprise an upper portion, a lower portion, a hinge, and a magnetic coupler. The hinge may be coupled to the upper portion and the lower portion and enables rotation between the upper portion and the lower portion only about a single axis. The magnetic coupler may be coupled to the upper portion and the lower portion and releasably maintains axial alignment between the upper potion and the lower portion by magnetic force.
