Abstract: A line striper 10 is equipped with additional features: including a speed/distance sensor 1 delivering high resolution and recognizing reverse movement. Also included is a built in programmable control 2 for setting parking stall or road line parameters including a measuring system. A device 3 applies paint marks (dots), or equivalent onto a surface. The striper 10 can hold a paint can 5 as a means of marking. An electrical thumb switch 4 is provided at the left handle bar. A speed compensating control provides intelligence to advance and retard the timing of actuation of the dot marking apparatus providing accuracy at any speed or direction.
