A golf training aide is attached to a golf club shaft and visually indicates to the golfer when the club shaft is held in a vertical plane and when the club head is held in proper angular relation to the ground. An indication of vertical alignment of the shaft is given when a first bubble is centered in a first bubble tube member and an indication of proper club head position is given when a second bubble is centered in a second bubble tube member. In a first embodiment, the second bubble tube member is linear-in-configuration and is rotatable about a horizontal axis. In a second embodiment, the second bubble tube member is arcuate-in-configuration and has a fixed position.
