Golf Gadget is a term used to describe the three essential items needed for a successful game of golf: a PEG, a TEE, and a ball retriever. A PEG is a small piece of wood or metal that is used to mark the position of a golf ball on the ground. A TEE is a small stand that holds the ball off the ground, allowing the player to hit it more easily. A ball retriever is a long pole with a scoop at the end, used to retrieve balls from hard-to-reach places. Together, these three items make up the essential golf gadget.
