Abstract

An adjustable height golf tee system having a tee and an anchor is discussed. The tee is height-adjustable relative to the anchor. A first anchor includes a cap, a stem, and a tip. The stem can be threaded internally, externally, or a combination thereof. A second anchor includes a base, a first stem, a cap, and a second stem as well as optional spacers. The stems can be threaded internally. Both the first and second anchors can be composed multiple pieces (e.g., a detachable cap, a detachable stem, or a detachable portion thereof) to provide access to an inner cavity of the respective stems.
