Abstract: A golf-tee mount is an apparatus that easily and effectively secures a golf-tee body into the ground. The apparatus includes golf-tee body, a mountable base, and a plurality of spikes. The golf-tee body upholds a golf ball that is about to be hit and is preferably made of a flexible material. The mountable base stabilizes and attaches the golf-tee body into the ground and allows the golf-tee body to be interchangeable as needed and is preferably made of a rigid material. Furthermore, the mountable base may remain connected with the ground while interchanging the golf-tee body. The plurality of spikes penetrates the ground and allows a user to easily fasten the mountable base, and consequently the golf-tee body, into the ground. The golf-tee body further includes a plurality of finger-receiving grooves that allows the user to better grip the golf-tee body while connecting the golf-tee body with the mountable base.

Abstract: A golf tee tether assembly for PURPOSE includes a cable has a length of no less than 19.0 inches. A pair of grommets is each attached to a respective end of the cable. Each of the grommets has an inside diameter of no more than 0.312 inches thereby facilitating each of the grommets to insertably receive a golf tee. A first one of the grommets is positionable at a drive location on a golf course to support a golf ball for driving the golf ball. A second one of the grommets is positionable at an anchor location that is displaced from the drive location. In this way the golf tee in the second grommet inhibits the golf tee in the first grommet from flying away when the golf ball is driven.
