The Stanley  Fat Max TruLaser Measuring tool is actually easier to use than a tape or wheel. The single button 'Aim-Shoot Measure' design means that anyone can pick up a unit and be measuring in moments. Adding complex measurements is automatic and error proof as is figuring square area and volumes. Additional features, such as area and volume calculations, are built into the Fat Max TruLaser Measuring tool and are not difficult to master. It really is a workman's tool.
