Installing the Battery
Ensure laser on/off switch is in the full off position. Remove the battery compartment cover
(11) by pressing down in on the center of the cover as shown in Figure 2 and pulling back.
Insert a fresh 9 volt battery making sure to match (+) and (-) terminals correctly. Replace the
battery compartment cover.
Operating Instructions
Scanning
Sensing elements for all modes of use are located in the lower part of the unit.
Stud Mode
For stud sensing through up to 3/4 inch (19mm) thick drywall.
1.) Move slide switch (6) to STUD position (5). Hold unit straight up and down
and place flat against wall as shown in Figure 3. Press in on the detector button (2) and
continue holding in button.
2.)The bottom red LED (8) will light and the unit will beep once while it is calibrating.
3.) Slide unit slowly, Figure 4, horizontally across surface of wall without lifting or tilting. When
the first red LED lights, slow down and keep sliding until the top green LED (9) is lit and beep
sounds as shown in Figure 5. This is the stud edge. Mark this spot (at arrow on lower part of
unit).
4.) Keep moving past mark until lights go out. Continue holding button and reverse direction.
Mark other stud edge. Center of stud is between two marks.
Metal Mode
For metal (iron, etc.) sensing up to 2 inches (51mm) thick drywall. For metal (copper, etc.)
sensing up to 1 inch (25mm) thick drywall.
1.) Move slide switch (6) to METAL position (4).
2.) Hold unit in air away from metal objects. Press in on detector button (2) and continue
holding in button. The bottom red LED (8) will light and the unit will beep once while it is
calibrating.
3.) Without releasing the button, hold unit straight up and down and place flat against wall as
shown in Figure 3.
4.) Slide unit slowly, Figure 4, horizontally across surface of wall without lifting or tilting. When
the first red LED lights, slow down and keep sliding until the top green LED (9) is lit and beep
sounds as shown in Figure 5. This is the edge of the metal object. Mark this spot (at arrow on
lower part of unit).
5.) Keep moving past mark until lights go out. Continue holding button and reverse direction.
Mark other edge of metal object. Center of metal object is between two marks.
Note: Because metal pipes or objects can be oriented both vertically and horizontally
behind a wall, you should scan both vertically and horizontally as shown in Figure 6.
AC Detection Mode
The sensor detects AC voltage and will identify only live wires. AC voltage detection feature
works continuously in all modes. It assists in identifying when the sensor is near live AC
wiring and detector button (2) is depressed. Once AC voltage has been detected AC wire
indicator LED (7) will light.
If the unit is calibrated close to AC wire, it may decrease AC wiring sensor sensitivity. Static
charge may spread detection 12 inch (30.4cm) on both sides of wire.
WARNING: 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. The sensor will not detect live wires inside metal pipe or metal conduit, behind
metallic wall covering, or behind some plywood or other dense materials.
Use caution if area has plywood, thick wood backing behind drywall, or thicker than normal
walls.
WARNING:
Always turn off the power when working near electrical wires, electric
shock may result.
Laser
Place unit flat against wall as shown in Figure 3. Push up on the laser on/off button (3) to
activate the self-leveling laser lines. To hang the unit on the wall, push pin (14) through
marking insert into drywall as shown in Figure 7. When pressing pin into drywall, make sure it
is straight and seated firmly in the marking insert and that the unit is secure on the wall.
CAUTION:
Pin is sharp and should be handled with care. NOTE: The drywall pin can only
be used with the marking insert (1), and is only for drywall, NOT other surfaces including
plaster. For surfaces other than drywall, the (key hole) hanging insert (12) can be used with a
standard screw or nail in a predrilled hole. Make sure it is straight and seated firmly in the
insert and that the unit is secure on the wall. The drywall pin should always be pushed in by
hand and never driven by a hammer. To remove the insert, push it out from the front side of
the unit.
Figure 8 illustrates a typical application for the Bullseye Laser Level when it is wall mounted.
When visibility is poor or when using laser outdoors, use the marking insert (1) to enhance the
laser line as shown in Figure 9. To extend the line, use the spacer insert (13) which is shown
in Figure 10.
NOTE:
Because the spacer insert keeps the unit farther from the wall, the stud
sensor can not be used when using the spacer insert.
DANGER: Laser Radiation, avoid direct eye exposure.
Helpful Hints
• If the laser light becomes dim or is no longer visible when the switch is in the on position
check or change the battery.
• The laser lines are only level on the wall against which the unit is held or hung. The short
line visible on any adjacent wall is not level.
• The laser unit is a wall use tool only and only generates level lines when held against a
vertical surface.
• The laser unit is equipped with a self leveling pendulum lock that stops pendulum motion
when the laser on/off switch is moved to the off position.
• If the laser on/off switch is pushed part way to the on position, the laser lines may be on
while the pendulum lock is still engaged.
• 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.
Possible Cause
• Weak battery.
• Nothing to detect in that
area.
• Check mode. May
have been calibrated
over a stud.
Solution
• Replace with fresh battery.
• Start again moving farther to either
side.
Problem
• LEDs do not light.
• 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.
• LEDs light in too many
places.
• Detects other objects
besides studs.
• Electrical wiring and
metal or plastic pipes
may be near or touching
back surface of wall.

• Replace with fresh battery.
• Be sure that the unit is as straight
up and down as possible.
• Laser does not project
on wall.
• Weak battery.
• The self leveling range
of the unit is +/-5
degrees, if the unit is not

will not project on wall.
• Laser projects on wall
but lines are not level.
• Wall on which the unit

leveling mechanism to
function correctly. If this
is exceeded, the lines
will still project but may
not be level.
• The laser on/off switch
must be pushed to the
