The LaserLine GL3000PMC Wing Plow-Tow Plow Guidance Laser reduces damage caused by wing strikes by better than 85%. The GL3000PMC uses an ultra-bright green laser-spot to establish a wing plow or tow plow’s trailing edge location before it is reached. The laser-spot impacts on the road/snow surface ahead of the truck in the driver's normal field of view, showing the driver where the plow trailing edge will be.
