A reusable compact device having a T-shaped plate with a tapering end, a cross member end, a central aperture, and a darkened perpendicular line between the aperture and cross member. When the golfer places the plate at ground level, points its tapering end toward the desired flight path of his/her ball, inserts a tee through the aperture and partially into the ground, places a golf ball upon the tee, self-aligns with the plate's tapering end, aligns the club face with the plate's cross member, and centers the club face to the exact ball center using the darkened perpendicular line, the golfer does not have to look up, position and stance are not lost during the swing, and the resulting swing is straightened, with improved accuracy and consistency in launching a golf ball along an intended flight path. Optionally, grooved tees are used to adjust ball height according to club type.

A device for attachment to a golf tee comprises a first marker to be aligned with the intended direction of travel of a golf ball and a second marker which lies generally normal to the first marker and which is intended to be aligned with the face of a golf club with which a golf ball supported by the tee is to be struck. The device includes an aperture through which the shank of a golf tee can pass to enable the device to be selectively attached to the golf tee. The device also includes a platform formed with a plurality of angularly spaced radially extending line indicators separate from the boundary of the aperture which enables the first marker to be offset from a true line to counteract inter alia a natural slice.

A hollow, rubber unitary golf tee is adapted to be placed upon a playing surface, the golf tee comprising a frustoconical portion, a playing surface engaging base, an upper surface and a centrally located ball support associated with the upper surface wherein the playing surface engaging base is greater in diameter than the upper surface.

A dime-sized annulus top end is provided for a golf tee. Also provided for the golf tee is a removable penetration cone which is a piece of stiff material with a pointed end for inserting into ground and an open hollowed end for receiving and securely holding a golf tee point. The annulus rim golf tee and removable penetration cone, while simple and unobtrusive, stabilize a teed golf ball, reduce re-teeing, and provide easy tee-insertion into all terrain.
