COMBINATION TOOL FOR ALIGNING, MEASURING DISTANCES AND SENSING OBJECTS UNDER A SURFACE

摘要

A combination tool (20) includes a housing (22) and a laser device (32) rotatably mounted on the housing (22) for projecting a laser line used for aligning and for projecting a laser beam used for aiming, a sonic device (36) coupled with the housing (22) for measuring distances between the tool and a spaced object, a sensor coupled with the housing for sensing objects hidden behind a surface, and a bracket attachable to the housing, the bracket having a. first position in which the housing is free to move over the surface and a second position in which the housing is secured in place over the surface.
