Abstract: A swing plane indicating golf mat capable of indicating the path of a swing through the critical zone. The golf mat includes an array of toggling, grass-mimicking blades which, from the vantage point of the golfer, assume a different appearance when toggled over. In the preferred embodiment, the blades have a forward face and a rearward face. The forward face and rearward face are different colors. Because of the curvature of the blades, the blades normally appear one color when the blades are in their normal and non-toggled position. When the blades are toggled, the blades appear a different color.
