The tool can be quickly set to your work by one of three means: attached by the retractable pin to wood or drywall, hooked over a screw with the eyelet, or fixed onto a metal stud using the strong magnet. Alternatively since the pin fully retracts into the plumb line holder, it can be held flush with the surface for zero distance measurements.
A quick-stabilising cap reduces bob wobble, making it faster and more accurate to use. The bob also has rubber side bumpers and a thick tip guard to provide protection. After use, the braided nylon line retracts into the case automatically.
