Stanley Stud Sensor 300
The Stud Sensor 300 uses electronic signals to locate the center of studs, joists
or live AC wires through drywall or other common building materials. Once
the center of a stud has been detected in one pass across the surface, the
Stud Sensor 300 gives a visual display and sounds an audible tone. A marking
channel allows you to easily note the stud center and edges on the wall.
The Stud Sensor 300 will not detect objects in concrete, mortar, block or brick
work, carpeting, foil faced materials, metallic surfaces or ceramic tiles. The
Stud Sensor 300 is not designed to locate non-ferrous or plastic objects such
as pipes.
Note: Read all instructions prior to operating the Stud Sensor 300 and DO NOT
remove any labels from the tool.
WARNING:
Protect Your Eyes, Wear Safety Goggles.
