A golf tee comprising an air channel is described. The tee has a longitudinal axis and a perpendicular axis. The tee has an intake near the lower portion of the tee cup and a channel connects this intake to the tee cup itself such that air entering the intake of the tee is redirected to exit the tee though the tee cup along the longitudinal axis.

The golf tee marking device can place a notch in a golf tee multiple times and at multiple heights, one height for drivers and another height for irons. The golf tee marking device comprising a housing for inserting and holding a golf tee, at least one lever having means for crimping said golf tee within said housing, when said lever is activated. Wherein said golf tee is positioned in said housing and said lever is activated by a user, said crimping means creates a notch on said golf tee to the correct height of the golf tee.

A golf tee set is provided with a keeper for preventing a tee from flying into a driving range or being lost, in which a first golf tee is tethered to a second golf tee, wherein a first point of attachment of the tether to the first golf tee is free of interfering force on at least the first golf tee, and wherein the tether is constructed of a filament having less weight, stiffness and resistance to twisting compared to a minimum weight, stiffness and resistance necessary to cause interference with the first golf tee loaded with a golf ball. The improved tether system avoids using holes in the tee, which can lead to breakage during play, and is removable to allow the user to select different tees for different game circumstances.

A golf tee has a contact alert material encapsulated therein. The golf tee includes a top portion with top, side and bottom walls fixedly attached to a shaft that terminates into a point appointed to be inserted into a ground surface. A cavity is formed between the top, side and bottom walls of the top portion. A contact alert material is encapsulated within the cavity and is composed of a combustible material that generates a spark on impact. The contact alert material is appointed to generate the spark during a golf swing when a golf club strikes the ball and the side walls. The alert is provided immediately as instantaneous feedback during the golf swing adapted to thereby improve muscle memory required to reliably replicate a proper golf swing.

A kit for building sand bunkers for accelerated water removal low maintenance multi-hole golfing facility. The sand bunkers are water permeable and water shuttling. Each kit creates a plurality of sand bunker each having a continuous bunker edge, a drain assembly, a synthetic tufted surface, a continuous integral edge overlapping polymer mesh, a non-woven dual smooth surfaced geo-textile, and a sand layer. Once built with the kit, the water in the sand bunker flows from the continuous bunker edge over the synthetic tufted surface, through the non-woven dual smooth surfaced geo-textile to the drain assembly while preventing the drain assembly from clogging, thereby maintaining an unclogged drain assembly for the water permeable and water shuttling sand bunker.
