A training device for golfer's wherein two separate narrow light beams are generated rearwardly of a golf ball support. The two light beams are perpendicular to each other and are continuously visible to a golfer throughout the swing as long as the golfer's head is moved only within a certain range. The angle of the beams is adjustable with respect to the ground to accommodate golfers of different heights. The width of the light beams can be made wider for less skilled golfers, and narrower for more skilled golfers.
