1.1 Preface
Dear customer,
all of the engineers, sales, training and support staff at OKM GmbH would like to thank you for your
purchase of the Black Hawk metal detector.
The Black Hawk pulse induction detector works on the principle of a time sensitive oscillator which
produces an alternating current that passes through a coil producing an alternating magnetic field. This
alternating magnetic field creates an eddy current which can detect electrically conductible metal. It
uses the induction of a high voltage energy pulse to identify the presence of metals.
The Black Hawk is able to locate buried objects within various structures and vessels non-intrusively
without having to e cavate the area. The facile and fle ible handling of the Black Hawk can easily and
quickly give 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 one of our products, we cannot guarantee that during the course of your
research that you will be successful and have a find. 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 where there is an e treme amount of ground water, varying clays,
sands and wet soils making scanning more difficult and may reduce the ma imum depth capabilities of
any and all 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 and when improvements or upgrades are available,
we will list them also 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, functionality
and how to utilize the Black Hawk. We also offer training for your equipment in our factory and on-site.
We strive to maintain worldwide dealer network for assistance and support. Please visit our web site for
more information.

1.2 Important Notes
Prior to using the Black Hawk and its accessories, please read these operating instructions carefully.
These instructions give information on how to use the detector and potential sources where precautions
should be taken.
1.2.1 General Notes
Being an electronic device, the Black Hawk has to be treated with caution and treated with care as with
any other electronic device. Any failure to observe the safety precautions given or any use for purposes
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 end user serviceable parts on the inside of the unit.
1.2.2 Possible Health Hazards
If used properly this device normally does not pose any health hazards. According to current scientific
knowledge, the high-frequency signals are not harmful to the human body on account of their low power.
1.2.3 urrounding Area
When moving this unit from a cold place to a warmer place, watch out for condensation. Do not operate
the unit until possible condensation has evaporated. The unit is not weather or water proof moisture
within the electronics 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 (150 ft) 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,
batteries and rechargeable batteries which are included within the scope of delivery.
Never use the 115/230 Volt mains supply.

1.2.5 Data Correctness
Data errors can occur if:
•the power supply of the device or the batteries are too low,
•the cables are too long,
•the unit is operating to close to devices which sends out disturbances or
•atmospheric conditions (electrical storms, lightning, etc...).
1.3 Maintenance and ervices
In this section you will learn how to maintain your measuring instrument with all included accessories 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 the appropriate carrying cases.
Prior to using your Black Hawk please be sure that all batteries and accumulators are fully charged. Also
do not allow the batteries to completely discharge before recharging them This way your batteries will
have a long and durable life. When the unit is not in use, recharge the batteries every 3 months so that
they retain their performance.
To charge the e ternal batteries use only the approved chargers which are part of our scope of
delivery.
1.4 Danger of Explosion during Excavation
Unfortunately, the last two world wars also made the ground in many places of the world a potentially
e plosive 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 indicator 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 or felt. The same applies to recognizable ammunition or bullets and shells. Leave that stuff
where it is, do not touch anything and, most importantly, do not take any of it home with you. The killing
machines of war made use of diabolical inventions such as 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. E plosives may have become crystalline over time, that is, sugar-like
crystals have formed.
Moving such an object may cause those crystals to produce friction, leading to an e plosion. If you come
across such relics, mark the place and do not fail to report the find to the police. Such objects always
pose a danger to the life of hikers, walkers, farmers, children and animals.
1.5 Care and Use
The Black Hawk is a sturdy instrument, but it is not designed to withstand abuse. In caring for your
Black Hawk, there are several important "DOs" and "DO NOTs" to remember.
•DO NOT use it to beat bushes out-of-the-way, 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 e posed at night where dew could form on it.
•DO NOT store it in places that could get e tremely hot.
•DO NOT leave it in the trunk or boot 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.
•DO use the detector with the proper power pack as to not cause damage to the unit.
The warranty does not cover damage resulting from an accident, neglect or abuse.
