A sonar device for positioning a second vehicle within relative proximity of a first vehicle, includes a light indicator having at least two light outputs. A controller has first and second settings calibrated to correspond to first and second signal strengths. The first signal strength corresponds to a near distance between the first and second vehicles. The second signal strength corresponds to a far distance between the vehicles. Based on the strength of a returned sonar signal, the controller actuates the light indicator to indicate when the vehicles are at the near distance from each other and when the vehicles are at the far distance from each other. The vehicle operators use the light indicators to regulate the actual distance between the two vehicles to be within the near and far distances.
