Abstract:
A method and device for allowing accurate sequential hole drilling locations in multiple floor and ceiling joists that includes a means for marking multiple holes without the need to measure, level and mark each individual joist or to run plumb lines. In one embodiment, the laser sighting device of the present invention includes a main body housing, a centering cone, an extension tube, and an adjustable center or bracket. A laser unit is positioned within the device and emits a laser from one end of the centering cone. A level allows accurate adjustment of pitch and yaw angles for a positioned orientation of the laser sighting device.
