MTC PROFESSIONAL
The revolutionary compact metal detector from
Picosens
The completely new and revised edition of the MTC
PROFESSIONAL offers you increased sensitivity and
precision metal analysis with a metal detector that fits in
your pocket.
The MTC PROFESSIONAL is powered by the patented AIS
industrial technology. It enables the best detection
sensitivity even in rough environments.
Special attention has been paid to the non-motion
functionality (no need to swing to detect anymore),
enabling the MTC PROFESSIONAL to be used in the private
and professional world of target detection (e.g. test
excavation).
Focus has been set on noble metals like gold, silver and
copper.
Free Android application
The application creates a brand new experience in metal
detecting. Create yourself a picture of the ground
beneath your feet, with its simple and intuitive user
interface.
Finding and precise identification of metal objects has
never been so easy.

Dual-Colored LEDs (blue/orange)
The dual-colored LEDs display the metal
quantity or depth (number of LEDs
lighting) and the material type
identification (color of the LEDs).
Moreover, the dual-colored LEDs are used
to see the status of the batteries and for
configuration.
Acoustic “Ping”
The acoustic feedback indicates the metal
quantity or depth in increasing steps.

Default factory configuration:
Using the free MTC PROFESSIONAL USER App, you can assign the orange color to
your required type of metal. Find more information concerning the functionalities
of the App on page 17.

1. Remove the battery cover by sliding it
to the right.
2. Insert the batteries (or rechargeable batteries) with the
correct polarity and replace the cover again.

1. Hold the MTC away from metal and ground.
2. Double click on Button 1.
Double click again on Button 1.
3 seconds
ON OFF
After 3 seconds, the LEDs will be turned off.
The MTC is now calibrated, and ready for
detection. The status LED flashes 1x per second.
Turn ON/OFF

Static metal analysis
Measurement without ground effect cancellation
The status LED flashes 1x per second.
(Automatic default configuration after startup.)
Use this detection mode in combination with your
smartphone and the MTC PROFESSIONAL USER app to
perform metal analysis.
In this mode the MTC PROFESSIONAL detects every type
of metal and also mineralized objects (concrete, burned
rock, …)
Best practice: Place the MTC PROFESSIONAL on a metal
free desk or table and start it.
Then approach a metal target to the MTC to analyze the
type of the metal using the visualization possibilities of
the MTC PROFESSIONAL USER app.
Pipes and cables detection inside walls
Measurement without ground effect cancellation
The status LED flashes 1x per second.
(Automatic default configuration after startup.)
Best practice: Follow the steps on page 16 to set the MTC
PROFESSIONAL in „Special low sensitivity“ mode. Then
move the MTC (as displayed below) perpendicularly to the
wall.

Detection modes

Outdoor metal detection
Measurement without ground effect cancellation
The status LED flashes twice per second.
Activation of ground effect cancellation: see next page.
Best practice : Activate the ground effect cancellation and
move the MTC PROFESSIONAL parallel to the ground,
without touching it.
You do not need to move fast (so you can have a precise
localization of the target) since the MTC PROFESSIONAL,
contrary to other metal detectors, does not need to be
swung.
Because of its mineralization, the ground produces a signal
that must be cancelled.
The MTC PROFESSIONAL has an embedded special “one
click” ground effect cancellation algorithm, to cancel this
effect without loosing detection sensitivity.
If the type of mineralization changes in the detection
area, you can reconfigure the ground effect cancellation
within a few seconds.

3. Now bring the MTC as close as possible to the ground
(without touching it).
The blue LEDs display the effect of the mineralization of the
ground.
After 3 seconds, the LEDs turn off, and you are ready to
detect without seeing any ground effect. The status LED
flashes twice.

clicking on the button 1 or 2.
4. After 3 seconds without button action, the MTC
saves the current selected sensitivity and goes back
to detection mode.
2. Release Button 2.
You are now in sensitivity configuration mode.

To detect cables and pipes inside walls, the sensitivity of the MTC
PROFESSIONAL is often too high and the measurement limit is quickly
reached.
In this case you can reduce the detection sensitivity of the MTC
PROFESSIONAL dramatically.
To exit the special low sensitivity mode, click Button 1 once.

Troubleshooting
Measurement limit reached
There is too much metal around the MTC. The
measurement limit has been reached.
If necessary, use the “special low sensitivity”
mode.
LEDs are lighting without metal
The environment (metal, ground
mineralization) of the MTC just
changed.
Hold the MTC in the air (away from
metal) and press Button 1 once to
calibrate.
LEDs stay OFF despite metal being close
Check the charge status of the batteries and replace
the batteries if needed.
Or:
You may have disabled the LEDs and/or the beeper
using the smartphone application.
Activate the LEDs display.

Connection problem
You cannot open the connection between the
smartphone and the MTC.
Restart the MTC and restart the smartphone
application.
