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 alone and where it is, do not touch anything and, most importantly, do not take any of those items home OKM GmbH www.okmmetaldetectors.com... - Page 11 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 or proper authority. Such objects always pose a danger to the life of hikers, walkers, farmers, children and animals. OKM GmbH www.okmmetaldetectors.com...

Page 33: General Measurement Procedure
Electrodes (electrodes with red socket) and the resulting voltage is measured with the two Voltage Electrodes (electrodes with black socket). By increasing (or decreasing) the distance of the Power Electrodes step by step the measure depth also increases (or decreases) accordingly, as shown in figure 6.3. OKM GmbH www.okmmetaldetectors.com... -
Page 34: Figure 6.3: Power Injection Depth Depends On Electrodes Distance
A … In this example each Power Electrode has to be placed in a distance of 5 m to the left and • right of the control unit. This corresponds to the power cable marker “1”. So you will unroll your cable until the marker “1” is reached and then you put the electrode into the ground. OKM GmbH www.okmmetaldetectors.com... - Page 35 • You have to move the Voltage Electrodes (black socket) inwards to another cable marker (several cable markers might be skipped). This will be necessary if the measured voltage is too high. OKM GmbH www.okmmetaldetectors.com...

Page 36: Setting Up A Measurement
After investigating your area you should place markers at each scan point. The distance of your 3 or 5 scan points can vary from situation to situation. The picture from figure 6.2 on page 33 shows an example of how to mark your scan points. OKM GmbH www.okmmetaldetectors.com... -

Place the control unit at the first scan point marker. Remove the voltage cable (10 m) completely from the Cable Drums. Connect the first plug of the Voltage Cable with the control unit. Make sure to use the end with the lowest marker number “1”. OKM GmbH www.okmmetaldetectors.com... - Page 38 Put the Voltage Electrode next to the cable marker into the ground as deep as possible. Use a hammer if necessary. Connect the Voltage Cable with the Voltage Electrode. Repeat steps 2 to 7 for the second Voltage Cable and Electrode. OKM GmbH www.okmmetaldetectors.com...
