1 INTRODUCTION
1.1 PREFACE
Dear customer,
our engineers, sales, training and support staff at OKM GmbH would like to thank you for your
purchase of the Rover UC.
The Rover UC detector works on the principle of Electro-Magnetic Signature Reading (EMSR).
Besides the detection of metallic objects this device is also capable of detecting natural features
of the earth like formations of strata, cavities, voids, faults, ground water and other non-metallic
objects. Then, of course, this equipment is best suited for the detection of sepulchers, treasures,
buried utilities, tanks etc.
The Rover UC is able to locate, document and analyze buried objects within various structures and
vessels non-intrusively without having to excavate the area. Using EMSR is particularly useful in
areas where detection is a must and excavation is not possible. The intuitive and flexible handling
of the Rover UC can easily and quickly provide reproducible results.
With our team of specialists we guarantee that our products are under recurrent control. Our
specialists try to implement new developments in terms of further quality improvements for you.
By purchasing or using our products, we cannot guarantee that you will be successful and have a
find during the course of your research. The recognition of hidden and buried objects depends on
a huge number of factors. As you well may know there are different soil types all over the world
with different levels of natural attenuation. Variable soil properties can and will hamper and alter
ultimate scan measurements. Areas with an extreme amount of ground water, varying clays, sands
and wet soils make scanning more difficult and may reduce the maximum depth capabilities of the
detection equipment, regardless of make or model.
For more information regarding where this equipment has been used and operated, please visit
our website. Our equipment is constantly being tested. Improvements and upgrades are listed on
our website.
It is necessary for our company to protect our developments and all of the information learned
during the “Research and Development” phases in creating our technology. We strive to stay within
the given framework of legislation, patents and trademark registration.
Please take your time to read this User Manual and familiarize yourself with the operation, func-
tionality and how to utilize the Rover UC. We also offer training for OKM equipment in our head-
quarters and on-site. We strive to maintain a worldwide dealer network for assistance and sup-
port. Please visit our website www.okmdetectors.com for more information.

INTRODUCTION

1.2 IMPORTANT NOTES
Prior to using the Rover UC and its accessories, please read these operating instructions carefully.
These instructions give information on how to use the detector and potential sources where pre-
cautions should be taken.
The Rover UC and its accessories serve for the analysis, documentation and detection of sub-
surface anomalies and ground disturbances. The recorded data of the ground structure will be
transmitted to a computer to give a visual representation using our proprietary software program.
Any additional notes to the software should be observed. Please refer to the Visualizer 3D Studio
Documentation!
1.2.1 General Notes
Being an electronic device, the Rover UC has to be treated with caution and treated with care as
with any electronic device. Any failure to observe the safety precautions given or any use for pur-
poses other than the ones it is designed for may result in damage or destruction of the processing
unit and/or its accessories or connected components.
The device has a built in anti-tampering module which will destroy the unit if it is improperly
opened. There are no consumer serviceable parts inside the unit.
1.2.2 Possible Health Hazards
If used properly this device usually does not pose any health hazards. According to current scien-
tific knowledge, the high-frequency signals are not harmful to the human body on account of their
low power.
1.2.3 Surrounding Area
When moving this unit from a cold place to a warmer place, watch out for condensation. Do not
immediately operate the unit until any possible condensation could have evaporated. The unit is
not weather proof and water or condensation can destroy the unit.
Avoid strong magnetic fields, which may occur in places where there are large electric motors or
unshielded loudspeakers. Try to avoid using this equipment within 50 meters (150ft) of this type
of equipment.
Metallic objects on the ground such as cans, tin, nails, screws or debris can influence your scan
data and present negative results regarding your scan data. Also it is a good habit to remove any
metallic objects off of your person like cellular telephones, keys, jewelry, etc. Do not wear steel
toe boots.
1.2.4 Voltage
The power supply can not be outside the indicated range of values. Use only approved chargers
which are included within the delivery scope.
1.2.5 Data Safety
Data errors can occur if:
• the range of the sender module has been exceeded,
• the power supply of the device or the batteries are too low,
• the unit is operating to close to devices which sends out disturbances or
• atmospheric conditions (electrical storms, lightning, etc.).
1.3 MAINTENANCE AND SERVICES
In this section you will learn how to maintain your measuring instrument with all included acces-
sories to keep it in good condition a long time and to get good measuring results.
The following list indicates what you absolutely should avoid:
• penetrating water
• strong dirt and dust deposits
• hard impacts
• strong magnetic fields
• high and long lasting heat effect
To clean your device please use a clean and dry soft rag or cloth. To avoid any damage you should
transport the device and accessories always in an appropriate way.
Prior to using your Rover UC please be sure that all batteries are fully charged.
To charge the internal battery
use only the approved charger which are part of the delivery scope.

1.4 DANGER OF EXPLOSION DURING EXCAVATION
Unfortunately, the last two world wars and other local conflicts made the ground in many places
of the world a potentially explosive scrap heap. A host of those lethal relics are still buried in the
ground. Do not start digging and hacking for an object wildly when you receive a signal of a piece
of metal from your device. Firstly, you might indeed cause irreparable damage to a truly rare find,
and secondly, there is a chance that the object reacts in an insulted way and strikes back.
Note the color of the ground close to the surface. A red or reddish color of the ground is an in-
dicator of rust traces. As regards to the finds themselves, you should definitely pay attention to
their shape. Curved or round objects should be a sign of alarm, especially if buttons, rings or little
pegs can be identified. The same applies to recognizable ammunition or bullets and shells. Leave
ammonition where it is, do not touch it and, most importantly, do not take any of it home with you.
The devices of war made use of rocker fuses, acid fuses and ball fuses. Those components have
been rusting away in the course of time, and the slightest movement may cause parts of them to
break and be Triggered. Even seemingly harmless objects such as cartridges or large ammunition
are anything but that.
Moving such an object may cause those crystals to produce friction, leading to an explosion. If you
come across such relics, mark the place and do not fail to report the find to the police. Such ob-
jects always pose a danger to the life of hikers, walkers, farmers, children and animals.
1.5 CARE AND USE
The Rover UC is a sturdy instrument, but it is not designed to withstand abuse. In caring for your
ground scanner, there are several important DOs and DON‘Ts to remember:
• DO NOT use to get rid of bushes, flatten area by swinging wildly or pry rocks loose.
• DO NOT drop the machine into water or use it while it is raining or wet.
• DO NOT leave it exposed at night where dew could form on it.
• DO NOT store it in places that could get extremely hot.
• DO NOT leave it in the trunk of a car where high temperatures could build up.
• DO NOT spray lubricants, or any type of cleaners, solvents, sealants or other chemicals into
or onto the electronic parts, switches or controls.
• DO NOT attempt to modify or repair the detector‘s electronics as this will void your detector‘s
warranty.
• DO clean your unit with a soft dry or slightly damp cloth to remove dust and residue from the
previous use.
• DO use the device within the proper operating guidelines.
The warranty does not cover damage resulting from an accident, neglect or abuse.
1.6 PROTECTING YOUR INVESTMENT
Often detector users become disappointed when their new detector becomes less and less
responsive and seems to have lost some of its original peak performance. You can help prevent
this from happening to your detector by following these basic care and protection guidelines:
• Operate your detector exactly as recommended in this User Manual.
• Use only approved OKM chargers.
• Avoid hitting the probe against hard, solid objects and surfaces.
• Keep your probe slightly off of the ground, especially when using in gravel or hard, rocky dirt.
• If working in or near water, or if there is a possibility of rain, use a protective weather resistant
pouch or plastic bag to cover the control housing. Make sure it can “breathe” in order to ensure
against condensation buildup inside.
• After each use, clean the detector with a soft cloth to remove dust, moisture or other conta-
minants.
• When transporting the detector in a car during hot weather, store it on the floor of the pass-
enger compartment if possible. Using the Protection case gives additional protection. In any
case, never allow the detector to roll around unprotected in the trunk or back of a pickup truck.
• Protect your detector from dust, moisture, and extreme temperatures during storage.
• When shipping, use the original heavy-duty container (Protection case) and provide sufficient
padding around all parts.
• Treat your detector as you would treat any sensitive electronic instrument. Though it is
designed to withstand the demands of normal treasure hunting, proper care is essential.

screen to correct your information.

5.3 MAGNETOMETER
The operating mode Magnetometer allows to research the area in regard to ferromagnetic
metals, e.g. iron, cobalt and nickel and other metals or objects which include traces of such metals.
Primarily, this function is an acoustic mode that additionally generates a basic graphical represen-
tation to visualize the peaks.
As soon as you get an acoustic signal, the device has detected a potential metal target right below
the position of the probe. In this way it is possible to find small metal objects near the surface like
nails, screws, wires, seals and similar targets.
A general rule is:
The fewer small metal items in the soil, the deeper you can detect targets with 3D Ground Scan.
5.3.1 Performing a Magnetometer Scan
In this operating mode all measured data will be directly displayed in the OKM Rover UC App.
Thus, we recommend to use the Magnetometer to remove disturbing metal items from the area that
you like to scan in detail. The less metals near to the surface, the better your result in the operating
mode 3D Ground Scan.
Moreover, Magnetometer can be used to pinpoint objects during excavation. If you have already dug
a large hole and do not remember where exactly the detected object was situated, you can relocate
fast and efficiently the target position.
1
Power on the detector and the Smartwatch. Start
the Rover UC App and select the operating mode
Magnetometer.
2
The Bluetooth connection to the detector will
be established automatically.
As soon as the Bluetooth connection is
established successfully, the Trigger LED
turns blue.
3
Move the probe slowly in any direction:
back and forth, to the left and to the right.
Make sure you hold the probe vertically to the
ground, avoid rotating, pivoting and swinging.
The scan results are displayed in real-
time on the Smartwatch screen.
As soon as a strong signal is detected, the
values will reach its peak when the probe is
directly above the detected object.
To pause the scan, tap on and continue
