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. (

To turn sound on or off

, press and hold the 

Mode/Audio Button for 2 seconds.
The tool has a backlit LCD display. 

To turn off the 

backlight

, press and hold both Power and Mode Buttons 

for 2 seconds. 

Repeat to turn the display backlight on again.

TURN TOOL ON / OFF

To turn on

, press and hold Power Button 

until display illuminates (approximately  

1 second). 

NOTE: Tool always powers up in Normal Scan 

Mode, indicated by icon to the right.

To calibrate

, turn tool on, then press and release 

Power Button.

To turn off

, press and hold Power Button for 3 seconds. 

Tool will turn off automatically after 2 minutes           of 

inactivity. 

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

found /–

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.
