Single person operation with use of adhesive putty
Ability to measure wall and ceiling thickness of most materials (i.e. wood, drywall, block and concrete with or without rebar)
Large window displays measurements of wall and ceiling thickness of most materials

Operating Range (In all Directions): 2in to 4ft 5in (5cm - 1.34m)

Accuracy (Tool Positioning):
Average Conditions: ±0.32" (8mm) for every 7.87" (20cm) thickness p to 3.28' (1m)
Ideal Conditions: ± 0.08"(2mm) for every 7.87" (20cm) thickness up to 3.28' (1m) (w/o metal influence)
Accuracy may be significantly reduced by irregular positioned rebar, welded reinforcing mesh, sheet metal, or other metal objects close to the tool. Please refer to the operating instructions for a detailed list of technical data.
