1.1 Unpacking and Inspection
Great care should be taken when unpacking the equipment.
Be sure to verify the contents shown on the packing list and
inspect the equipment for any loose parts or other damage. All
packing material should be preserved in the event that any
damage occurred during shipping. Any claims for shipping
damage should be filed to the carrier. Any claims for missing
equipment or parts should be filed with Mala GeoScience.
1.2 Repacking and Shipping
If original packing materials are unavailable, the equipment
should be packed with at least 80 mm of shock-absorbing
material. Do not use shredded fibres, paper wood, or wool, as
these materials tend to get compacted during shipment and

1.4 Important information regarding the use of
this MALA GPR unit
According to the regulations stated in ETSI EN 302 066-1 (European
Telecommunication Standards Institute):
- The CX unit should not be left ON when leaving the system unintended. It
should always be turned OFF when not in use.
- The antennas should point towards the ground, walls etc. during
measurement and not towards the air.
- The antennas should be kept in close proximity to the media under
investigation.
Canadian regulations states that whenever GPR-antennas are in use the
following note apply:
This Ground penetrating Radar device shall be operated only when in
contact with or within 1 m of the ground.
This Ground Penetrating Radar Device shall be used only by law
enforcement agencies, scientific research institutes, commercial mining
companies, construction companies and emergency rescue or firefighting
organizations.

2 Hardware and Start Up
__________________________________________________
2.1 Hardware
The EasyLocator HDR is a GPR system with integrated,
height-adjustable wheels. The main components are the UWBtransducer(antenna), the monitor the mechanical carrying
system and the batteries. The system is, preferable powered
with one battery and data communication between the GPRtransducer and the monitor is managed with an Ethernet link
on a cable which carries power to the monitor as well, see
figure below.
2.2 Start up
Prior to surveying with the system the following easy steps
should be followed.

Make sure that the battery is fully charged. The battery
powers both the transducer and the monitor and is good
for about 5 hour’s operation.
www.malags.com

Connect the traducer to the battery by means with cable
supplied, see picture below.

Connect the Monitor to the transducer with the cable
supplied, see picture below.

Press and release the button the GPR-transducer,
shortly, do keep it pressed. This will start up the unit;
the LED’s on the panel will start to blink as well as the
LED inside the button, see figure below.
www.malags.com

Press the button on the monitor; it’ll take about 30
seconds for the unit to start up.
After these simple steps the monitor will display the screen shown in
figure below, and the system is ready for operation.
www.malags.com
3 Using the EasyLocator
HDR
The EasyLocator is shipped folded, with monitor and cables
attached, but without the battery mounted. You need to
connect the two battery-packs together and mount the in the
battery bay (this is due to shipment regulations for Li-Ion
batteries). In figure below a folded EasyLocator ready for
shipment is shown.
In order to unfold the unit; just lift the monitor to upright
position and fasten the clips on the side of the shackles. See
figure below.
www.malags.com
Once the unit is un-folded and started as described in previous
paragraph, operation is very straight-forward and selfexplanatory, some details will be described in the following
text.
Referring to the start-up screen is shown in figure below, the
area of the screen between the depth scales are reserved for
data presentation, the lower portion for information about the
ongoing survey and the right column are mainly for controlling
the instrument trough the turn-push button.
Starting from the top-right:
The yellow circle with a cross-hair is indicating the GPS-status;
red means that there’s no GPS attached or no satellites
available, yellow means normal GPS accuracy (about 10m)
and green means that the unit has been able to apply
differential correction.
www.malags.com
10
The scale with red, yellow and green indicates the battery
status. It is divided into two black bars, since there’s an option
of using a separate battery for the transducer. In other
respects, this scale is self-explanatory.
The Quit button is also self-explanatory, press on this and
you’ll have the option for turning off the unit. Note that the unit
should always be turned off this way, since just pulling the
power cable may harm the internal memory of the unit.
Pressing the “Start” button will immediately put the unit into
data collection mode and a radar image of the subsurface will
start to display as soon as the unit is moved.
The camera button enables the operator to save a jpeg image
of the current screen for later downloading to a USB device.
This is intended for documentation purposes.
The wrench button gives possibility to change some of the
settings controlling the data collection process and housekeeping functionality in the unit, see separate section of this
manual.
The last 3 buttons controls filter to be applied on the data, prior
to display, they are, top to down, background removal, contrast
level and gain function. Pressing the push-turn button while
turning it increases or decreases the strength of these filters,
right-turn; increase and left-turn; decrease.
The bottom part of the screen shows some information about
the ongoing survey. It’s self-explanatory except for the triggertype field. The trigger type field explains what controls the data
acquisition, there’s three different types of control; forward
wheel, backward wheel and time triggering. Time triggering
means that the unit collects data with certain frequency,
normally 10 to 20 Hz; it is to be used when surface conditions
prohibit the use of a wheel.

3.1 Surveying
When a survey has been initiated the main menu changes,
see figure below. Now the user may stop the survey, save a
jpeg-image of the current screen check the velocity trough
hyperbola fitting or save a GPS-marker on the current location.
An important feature in the instrument is the track-cursor
pointed to by the red-arrow in the figure. This cursor will move
with the system, so that if the unit is moved backwards, this
cursor along with a vertical line will start to move back on the
screen. This is the primary function used when locating buried
targets. When the unit is pushed forward again, data collection
will start when you reach the point where you started to move
backward, not before.
Track-cursor

3.2 The settings menu
The settings menu is entered through the wrench button on the
main menu; it is shown in figure below.
Activating the green text-fields, but turning the push-turn
button, and then depressing it gives the user means for
changing the settings. Below the different options are
described.
Color, the user can switch between gray-scale and color
scale for the displayed radar data. The vast majority of
users prefer the grey-scale, since there’s no natural
interpretation of color for this type of data. It can actually
be quite confusing.
The sun-symbol is for setting of the backlight of the
screen, default is 100%. By lowering this parameter,
battery-life can be extended by up to 1 hour.

-
Soil Type, is defining which ground velocity should be
used when converting reflections from a specific time to
a depth to be shown on the scales. Note that this type
of instrument actually measures time of flight for
electromagnetic waves, in ground. The depth displayed
on the scales is estimations only. Variations in normal
ground are between 80 to 120 meters/microseconds. A
user must be aware of this fact.
The System Parameters sub-menu is not accessible for
operators; it is used for factory calibrations, service centers
during manufacturing and service/repair
The other sub-menus are self-explanatory. Contact your local
dealer if further information is needed.
