Abstract
A specially designed line marking device includes a marking string that is attached to a bow-shaped support structure with no free end for conveniently use by a single operator, a shuttle for coating the marking string with marking media prior to use, allowing an operator to effectively use this marking device and snap a marking line onto a working surface without the assistance of an additional operator, and a movable carriage containing liquid, powder, or aerosol marking media to be sprayed or deposited along said marking string, creating an inverse image of the marking string.
