WARNING:
To reduce the risk of injury, user must read and understand instruction

Safety Instructions
• Do not operate the stud sensor in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust.
• Use the stud sensor only with 9 volt alkaline battery. Use of any other batteries may create a
risk of fire.
CAUTION: Material thickness, type of material, moisture content, and other variables can
effect sensing results. The sensor may detect electric wiring or pipes in the same manner
that studs are detected depending on their location to the wall surface. Use caution when
drilling, nailing or cutting into walls, floors and ceilings which may contain electrical wiring or
pipes. These items may be detected by the sensor in the same manner in which studs are
detected. Because studs are normally spaced 16 inches (406 mm) or 24 inches (610 mm)
apart and are usually 1-1/2 inches (38 mm) wide, beware of anything closer together or of
a different width.
Always turn off the power when working near electrical wires.

Operating Instructions
INSTALLING THE BATTERY
Remove the battery compartment cover (H) by pressing in the tab in the center of the cover
and pulling back. Insert a fresh 9 volt alkaline battery into compartment and connect to battery
cable. Replace the battery compartment cover and snap shut.
CALIBRATION AND SCANNING
CALIBRATION
1.) For stud sensing, move slide switch to STUD position. Hold unit straight up and down and
place flat against wall as shown in Figure 2. For METAL sensing, move slide switch to METAL
position and calibrate by holding unit in air away from metal objects. For WIRE sensing, move
slide switch to AC WIRE position and calibrate by holding unit in air away from a “live”
unshielded electrical wire.
2.) Press in and hold the sensor ON/OFF button (G) while calibrating and continue holding in
button while scanning.
a.) The upper GREEN LED (A) will light,
b.) The unit will beep once while it is calibrating,
c.) The bottom RED LED will light.
SCANNING
STUD MODE FIGURE 2A
For stud sensing up to 3/4 in. (19mm) deep.
1.) After calibration, while still holding in button, slide sensor slowly, (Figure 2) horizontally
across surface of wall without lifting or tilting.
2.) The upper GREEN LED will light and a beeper will sound when an edge is detected, mark
that spot as shown in Figure 3.
Repeat this cycle coming from the other direction to confirm the mark.
METAL MODE FIGURE 2B
For metal (iron, etc.) sensing up to 2 inches (51mm) deep. For metal (copper, etc.) sensing up
to 1 inch (25mm) deep.
1.) After calibration, while still holding in button, slide sensor slowly across surface without
lifting or tilting.
2.) The upper GREEN LED will light and a beeper will sound when you are close to a metal
object, mark that spot. Reverse directions to locate other edge of target and mark spot. The
center of the two marks will be the center of the target object.
AC WIRE MODE FIGURE 2C (BDL153S ONLY)
For wire sensing up to 2 in. (51mm) deep.
1.) After calibration, while still holding in button, slide sensor slowly across surface without
lifting or tilting.
2.) The upper GREEN LED will light and a beeper will sound when you are close to a “live”
wire, mark that spot. Reverse directions to locate other edge of target and mark spot. The
center of the two marks will be the center of the target object.
The sensor detects from 90 to 250 V at 50 to 60 Hz AC in a “live” unshielded electrical wire.
WARNING:
Always turn off the power when working near electrical wires, electric
shock may result.
Occasionally, pipes and electrical wiring may not be detected by this product. Observe
caution when cutting or drilling into areas that may contain concealed pipes or wiring. Always
turn off power when working near electrical wires. The sensor will not detect hot wires inside
metal pipe or metal conduit, behind metallic wall covering, or behind some plywood or other
dense materials.
AC DETECTION MODE
The sensor detects AC voltage in all settings. It assists in identifying when the sensor is near
AC wiring. Use the AC switch mode to fine tune the location of the wiring. Static charge may
spread detection 12 in. (30.4cm) on both sides of wire.
WARNING:
Always turn off the power when working near electrical wires, electric
shock may result.
Occasionally, pipes and electrical wiring may not be detected by this product. Observe
caution when cutting or drilling into areas that may contain concealed pipes or wiring. Always
turn off power when working near electrical wires. The sensor will not detect hot wires inside
metal pipe or metal conduit, behind metallic wall covering, or behind some plywood or other
dense materials.
TIPS FOR OPTIMUM USE
• Test batteries before each use. Press and hold the on/off switch until the RED LED remains
on. Then move your free hand toward the back of the unit. The GREEN LED should illuminate
and then go out as you move your hand away from the unit. Replace the batteries if the
GREEN LED does not illuminate.
• Hold stud sensor straight up and down.
• Because studs are normally spaced 16 inches or 24 inches apart and are 1-1/2 inches wide,
beware of anything closer together or of a different width. Doors and windows are
constructed with studs and headers which are closer together.
•
Avoid materials which have inconsistent density such as:
• Carpeting and padding
• Ceramic floor tile
• Wallpaper containing metallic foils or fibers. Generally, surfaces covered with regular
wallpaper or fabric will scan with no difference in function.
• Walls that are freshly painted and are still damp.
• Excessively thick plaster and lath.
Maintenance
Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.
