General information
General information
VIY5-125. New generation of Ground Penetrating Radars.
Ground Penetrating Radar (GPR) is designed for non-destructive scanning and inspecting of different
structures and underground objects.
GPR can be applied by geophysicists, building companies, can be used in different ecological investigations,
utilities condition assessment (including both metallic and non-metallic, plastic, concrete, asbestos pipes).
Also the equipment can be used for searching and mapping of: underground water sources leaks, oil and
other dangerous liquids underground pollutions; ground water level.
VIY5-125 Ground Penetrating Radar (GPR) has Dual Frequency antenna with central frequencies of 125
MHz.
Application of VIY5-125 GPR
• Utilities mapping and detection (pipes, cables);
• Civil engineering surveys (building basements, cellars etc.);
• Search for buried waste products, and graves;
• Mapping and location of near surface voids, karst and other cavities;
• Determination of boundaries of petroleum contamination zones etc.
• Forensic and security investigations.

Push-pull connectors.
To connect push-pull connectors you should open cap then match together the white marks on a plug and a
socket correspondingly and then insert the plug by holding its housing.
To disconnect - just pull the plug ring back and disconnect it.

Mounting the laptop shelf on the operator’s backpack
If GPR is used together with VO-22 odometer, the laptop should be mounted on the special portable shelf
that should be fastened to the operator’s backpack.
To mount the laptop shelf follow the next steps:
• Take the laptop folder out of the backpack.
• Stick the Velcro tape on the top of Handcart shelf and on the laptop bottom in some places (the Velcro
tape is included in GPR set).
• Turn the shelf over and pull out the metallic holders (in direction shown by an arrow below).

Getting Started
• Turn the metallic holders 90 degree aside and put them into slots as shown on the picture below.
• Put the backpack on, adjust the backpack side stripes and fasten the backpack belt.
• Fasten operator’s shelf locks to the corresponding locks on the backpack stripes
• Tuck he lower holders of the shelf behind the operator’s backpack belt.

GPR battery
GPR battery
Each antenna unit is equipped with the sealed lead acid rechargeable battery (12 V, 7 Ah). The power supply
of the antenna unit prevents the deep discharge of the battery. The battery charge level is indicated in the
Status bar of the Main window of the Synchro3 software the battery.
When the battery voltage is low and close to the critical value, the power supply begins beeping. When the
battery voltage is below the cut-off threshold (10.8V) the power supply will turn the antenna unit off but beep
sound will continue ringing twice per second. That indicates the normal state of GPR and the necessity of
battery charging.
For battery charging use the charger that is included in GPR set.
Charging battery of VIY5-125 GPR
For charging the battery of VIY5-125 GPR you should connect the charger plug into DATA socket that is
located on the Handcart (or into DATA socket on a Battery Box if connected), and then plug the charger to
the AC power (220-240V AC, 50-60 Hz).
Charging battery with antenna installed on the Handcart.
The battery is inside the battery compartment in the Handcart:

9To get more information please read the charger User manual that is in the charger set.
Battery replacement
All models of GPR use the same standard sealed lead acid rechargeable battery (12 V, 7 Ah).
9To get more information please read the charger User manual that is in the charger set.
To 220-240 AC
If you notice the Charger error light is on during the
charging process, it means that your battery must
be replaced for the new one.
