USE THE HANDLE
The tool can be used as a handheld tool or the
pivoting handle attachment (and optional pole extension)
can be used to extend your reach, provide a wider range
of motion, and help to reduce interference with the tool's
sensors.
To attach handle to the tool:
1. Open the hatch by pressing the
dimpled area. The hatch will lift up.
(
Figure C)
2. Align the handle so that the
button on the tip of the handle is
flush against the hatch door.
Push down gently until it snaps
securely in place. (
Figure D)
To remove the handle:
1. Hold the tool in place with one
hand.
2. With the other handle, pull the
handle up from the base.
To use the optional extension pole
(sold separately), first assemble
the pole sections together into the
length you will need, then align the
threaded end of the pole with the
bottom of the handle and screw
securely into place. (

SCAN IN NORMAL SCAN MODE
This tool is designed to locate metal behind or beneath a
surface, including concrete. It can locate metal as deep as
6" (15 cm), depending on the settings used.
It is specifically tuned to locate
1
⁄2" (13 mm) copper pipe
and #4 rebar. For other metal objects, depth readings will
be less accurate.
• #4 steel rebar and
1
⁄2" (13 mm) copper pipe can be
found within +/–
1
⁄2" (13 mm) accuracy in both Normal
and DeepScan Modes
• Small objects, like nail heads, will be shallower than
indicated
• A
1
⁄4" (6 mm) copper pipe will be about 30% shallower
than indicated
• A
3
⁄4" (19 mm) copper pipe will be about 2% deeper
than indicated
NOTE: For best results, calibrate tool away
from metal.
As you move the tool toward a target, the Plus / Minus
icon will show
. If you move away from the target,
it will show
.
1. Before scanning, clear debris, including sand and
gravel, from the area. If the scanning surface is rough,
cover it with thin cardboard. (The thickness of the
cardboard should be subtracted from the depth reading to
determine the actual depth of the target).
2. Scan from side to side.
(
Figure A)
As you near a target, the Magnet
Icon will show. (
Figure B)
The
icon indicates that the target
is ferrous (magnetic) metal. The
indicates a non-ferrous target.
If Audio is on (
), a tone will emit
when over the target.
The Depth Indicator also shows the
approximate depth of the target.
3. Mark this spot.
4. When the tool goes beyond the
target, the
changes to .
Reverse direction, and the icon will return to
.
5. Mark this spot as well.
The midpoint between the two marks is the approximate
location of the metal target.
6. Scan the same area, but in a vertical direction.
Repeat the scan for multiple targets, or to fully identify
target using a grid pattern, marking each target as found.
USE DEEPSCAN MODE
To use DeepScan Mode:
1. Turn tool on. It always starts in Normal Scan Mode.
2. Press and hold both Power and Mode Buttons for
1 second, then release. (If you hold for 2 seconds, you will
turn off the display backlight.)
3. Follow steps 1–6 as described under SCAN IN
NORMAL SCAN MODE.
To return to Normal Scan Mode, press the button again,
or turn the tool off and then back on.
RECALIBRATE FOR MORE ACCURACY
The MT 7 calibrates automatically when the tool is turned
on. However, depth accuracy is dependent on materials in
the vicinity of the scan, particularly when metallic minerals
may be present in the concrete,
as is common.
Recalibration will not affect the position accuracy but will
be helpful in making a final determination of depth.
• If the tool is unable to calibrate for any reason,
all icons on the tool’s display will flash. If this happens,
there is too much metal near the tool to calibrate
properly. Move the tool to another location and perform
the calibration process again by quickly pressing and
releasing the Recalibration Button.
• If the target is near a large mass of metal, the tool may
not be able to locate the center. Recalibrate and/or move
the tool away and move back slowly.
• If the tool is calibrated too close to the target, it
may indicate there is no metal in the area when
there is. To check this, calibrate the tool in several
locations, then compare results. Always perform several
scans of an area to confirm that consistent results are
achieved.
To recalibrate:
1. Locate an area on the surface free of metal. If a tight
pattern exists, calibrate at a midpoint between targets. In
this situation, accuracy may be affected and recalibration
may not improve the overall depth accuracy.
2. Scan the target area again. A final determination of
depth can now be obtained.

BEFORE YOU BEGIN
- Always use a new alkaline battery with an extended expiration date at least 3 years beyond the current date.
Be sure not to pull on wires when disconnecting an old battery.
- Do not rely exclusively on the tool to locate items behind a surface. Use other information to help locate such
items before penetrating the surface, including construction plans and visible points of entry of pipes and wiring into
scanned surface.
- Readings should always be consistent and repeatable.
- Other objects commonly contained in walls, floors, or ceilings are water pipes, gas lines, firestops, and electrical wiring.
- Sensing depth and accuracy can vary depending on scanning environment conditions such as mineral content, moisture,
texture and consistency of the wall materials.
- Always turn off power when working near electrical wires.
- Depending on the proximity of electrical wiring or pipes to the wall surface, the tool may detect them in the same
manner as other metal. Caution should always be used when nailing, cutting, or drilling in walls, floors, and ceilings that
may contain these items.
- Targets deeper than 6" (15 cm) may not be detected.
- Avoid wearing jewelry, including a watch, while scanning, as the metal in the jewelry could interfere with readings.
TROUBLESHOOTING & CONSTRUCTION TIPS
SITUATION LIKELY CAUSE SOLUTION
Difficulty detecting
metal accurately.
Metal objects grouped too
closely prevent calibration.
• Avoid wearing jewelry, including watches, during scan. Remove large
metal tools from area when feasible.
• Use a constant light pressure during scan.
• Allow 5 – 10 minutes for temperature to stabilize before operating if
unit has been moved to an area with a 10ºF (5 – 6ºC) change or greater
(such as from air-conditioned building to outdoors on a warm day).
• Scan in both horizontal and vertical directions.
Inaccurate calibration
and/or depth reading
because magnetic/
non-magnetic objects
positioned side-by-
side or on top of
each other.
• Calibrated directly over
a metal target.
• Concrete and rebar are
in segments that could
have been poured at
different times.
• Calibrate away from metal to accurately determine depths. Move the tool
over a few inches (5 – 8 cm) and recalibrate.
• Make sure the tool touches the surface it is scanning.
• Do not rely on a single calibration for the entire area. Prescan each
segment separately; calibrate and determine depth of targets for each
segment of concrete.
• For maximum accuracy on concrete, make sure the concrete is fully cured.
Calibration is lost. Tool was turned off. Recalibrate every time you turn tool on.
Beep doesn’t seem
relative to targets.
• Scanning near the edge
of a piece of concrete.
• Target is more than 6"
(15 cm) deep; unit will
not beep at the same
time as Plus / Minus Icon
changes and maximum
depth bars appear.
Ignore beep and rely on depth bars to locate target.
Backlight and all
icons are on.
A calibration error
has occurred.
Reposition the tool and recalibrate.
Low Battery
Indicator flashes.
Low battery. Install new 9-volt alkaline battery with an extended expiration date.
