A mobile apparatus and method to accurately transfer one or multiple points on one surface to one or multiple points on another surface, such as a reference line or markings on a floor to target points on an overhead ceiling for hanging support brackets. The apparatus includes a base supported by four wheels and a leveled top plate to facilitate use on uneven surfaces. Laser brackets mounted on said top plate support fixed lasers for single point layout. Laser brackets mounted on the ends of transversely movable support arms support movable lasers from said top plate for dual point layout. Vertical pointers on said base position the base on the floor markings. A linear measurement device accurately measures linear movement of the apparatus along the floor surface. A drum attachment supports a laser to provide indicator lines along radiuses in a horizontal and vertical plane.
