MetalliScanner m40
Electronic Metal Detector
The MetalliScanner m40 electronic metal detector
locates metal through concrete and most nonmetallic
materials. The wide and pinpoint scanning positions
allow you to quickly and easily find plumbing, ductwork,
rebar, nails and screws in your walls, floors and
ceilings. Find studs in lath and plaster walls by locating
the row of nails attaching the wood lath to the studs.
MetalliScanner m40 is also great for scanning
reclaimed or recycled lumber before sawing and
planing to find hidden metal.
WIDE AREA SCANNING
1. Grasp the tool with
your thumb over the
power button.
2. Hold the tool in the
air with the blue
sensor parallel to the
scanning
surface
away from any known
metal.
3. Press and hold the
power button. The
Ready light indicates
that calibration is
complete and you are
ready to search for
metal.
4. Move the unit near the surface and scan while
continuing to hold the power button. Do not rotate the
tool, see Tip #3.
5. As you approach a metal object the red LEDs will
light progressively from the bottom up. The closer the
illuminated lights get to the top, the closer you are to a
metal object. The illuminated blue sensor and audio
tone indicate a strong target. Small targets or targets
deep within the surface may only illuminate some of
the red LEDs and not the blue sensor or audio tone. In
this case, use the highest LED indication to determine
the metal position.
6. Mark the point where you get the highest LED
indication, continue scanning and mark the point where
the LED indication decreases. Halfway between these
points is the logical centre of the metal field. To further
refine this position see Tip #1.
PINPOINT SCANNING
1. Grasp the tool with
your index finger over
the power button.
2. Hold the tool in the air
with the blue sensor
perpendicular to the
scanning surface away
from any known metal.
3. Press and hold the
power button. The Ready
light indicates that
calibration is complete
and you are ready to
search for metal.
4. Move the unit near the
surface and scan while
continuing to hold the
power button. Do not
rotate the tool, see
Tip #2.
5. As you approach a metal object the red LEDs will
light progressively from the bottom up. The closer the
illuminated lights get to the top, the closer you are to a
metal object. The illuminated blue sensor and audio
tone indicate a strong target. Small targets or targets
deep within the surface may only illuminate some of
the red LEDs and not the blue sensor or audio tone. In
this case, use the highest LED indication to determine
the metal position.
6. Mark the point where you get the highest LED
indication, continue scanning and mark the point where
the LED indication decreases. Halfway between these
points is the logical centre of the metal field. To further
refine this position see Tip #1.
7. Scan the surface both vertically and horizontally to
pinpoint the metal target location.
LOCATING STUDS IN LATH & PLASTER
1. Scan across the wall using the Wide Area Scanning
procedure
outlined
previously to locate the
nails that attach the wood
lath to the studs.
2. To help confirm you
have found a stud and
not a pipe or other metal
object, scan the target
area located in Step #1
again, this time using
Pinpoint Scanning, and
scan the area vertically.
The LEDs may move up
and down on the display,
indicating the nail pattern of the small nails attaching
the wood lath to the stud. (In contrast, a pipe or other
solid metal will typically be indicated by a consistent
signal.)
3. To help verify your findings, scan your work area
thoroughly and mark the location of every object
indicated by the tool. Do not assume that everything is
a stud.
• Studs are normally spaced 16in (40cm) or 24in
(60cm) apart, not odd intervals.
• Studs normally run from floor to ceiling, except above
and below windows and above doors.
• Pipes and other large metal objects will give a
consistent, strong signal in either scanning mode. The
nails in a stud will likely show some variance in the
strength of the signal.
• Be aware of walls that are likely to contain plumbing.
For example, a living room wall may be common to a
bathroom and contain plumbing for the sink, shower or
toilet.
Tips:
1. If the unit indicates metal over a large area, you can
refine the scanning area to more accurately locate the
metal target. After scanning the area as indicated
above, mark the edges of the area where you get the
strongest metal signal. Starting over one of the marks,
press and hold the power button; this will recalibrate
the tool and decrease the sensitivity. While holding the
power button, scan the area again. The area indicated
should become smaller so you can more precisely
identify the metal location. This procedure can be
repeated to narrow the field even further.
2. Because the unit uses signal strength to determine
position, large, deep objects and small, shallow objects
will give similar indications.
3. The unit should be turned on in the same orientation
that will be used when scanning. If the tool is twisted
or rotated during use, you may get a temporary
indication of metal where none is present. Wait until
ONLY the Ready light is on before scanning.
4. MetalliScanner m40 finds ferrous (magnetic) metal
such as ½in (12mm) rebar to 4in (102mm) deep and
non-ferrous (non-magnetic) metal
such as ½n (12mm) copper pipe up
to 2in (51mm) deep. Targets found at
the maximum depth may only be
indicated by the first red LED on the
display.
5. When scanning concrete, the tool
will indicate the presence of the
metal mesh that is usually found in
driveways and slab foundations, but
due to the size variety of metal mesh,
the tool may not indicate the exact
location of the wires.
6. Magnetized materials may cause
false indications.
CHANGING THE BATTERY
1. Remove the battery cover located
below the power button by pressing in on
the arrow and sliding the cover towards
the bottom of the tool.
2. Holding the tool upside-
down, tilt the battery out of the
cavity.
