7. the measurement result needs to be very accurate In terrains with difficult access like mountain cliffs and sides slippery surfaces or overgrown areas it is wise to use the manual impulse mode Because each impulse will be released manually you have enough time to position the probe in the correct way and record the measured value In this way you can also measure accurately previously marked dots of a predefined grid 7 2 4 Tips from the trainers themselves When conducting scans there are some extremely important items that need to be noted First of all it is crucial that you relax When you are tense you are putting too much pressure on yourself to do the scan correctly often resulting in errors e Newly buried targets are difficult to see Many users receive the equipment and the first thing they do is go out and bury an object When an object goes into the ground it changes the natural signature of the soil and creates some kind of noise Usually the buried object has a weaker signature than the unnatural noise and therefor is not detectable So taken scan images will not show the buried item but visualize the noisy area in blue colors After the item has been seasoned meaning it has been in the ground for a complete cycle of seasons usually a year the noise gets reduced and the signature of the buried object becomes visible again e Train on known targets In the training course at the factory we have several objects that have

29. l scans When you scan an area for example three time over the same starting and stopping points remember this basic rule Real Targets Don t Move If in your second and third control scans you realize that nothing is staying in the same place most likely there is nothing there and you are looking at a patch of mineralized soil OKM GmbH www okmmetaldetectors com 50 General Data Analysis Figure 8 1 Ferromagnetic signal representation In figure 8 1 is a typical ferromagnetic signature shown It is not difficult to know the exact characteristics The red and the blue directly next to one another is the key Normally the colors will have approximately the same size and shape 8 3 Establishing a background color When viewing a scan try to see which color is dominant throughout This is your background color In normal soils it will typically be green with some lighter and darker shades There are conditions where the color may be completely different like blue This may happen in different soil conditions that have stronger mineralized soils 8 4 Search for anomalies After you have established what the background color is now it is time to look for the anomalies If you see a distinct color difference this may be a possible anomaly It will be very recognizable from the background whereas when rotating and viewing the suspect will be a large difference You can also view the scan from the side At this point you w
30. le to identify the exact location of the target If you find an anomaly only on the edge of a scan change the size of your scan so that the area scanned is including the suspect area Only when a target is directly in the center of a scan can a proper analysis be made 8 7 Determining the difference from metal or mineral When you come across an area where you see darker oranges and reds in the scan it is important to determine if it is indeed a metallic object or if the ground is highly mineralized Naturally soils that are highly mineralized will quickly be known for all the scans in the area will show nearly the same For the beginner this can be very frustrating to decipher the difference And there are even areas of soil which have high concentrations of iron that will show red This is where the control scans are imperative take care as to all of the details during a control scan to ensure that it is performed properly Below are some notes to tell the difference Form or shape Does the object have a recognizable shape for example right angle edges circle etc This is one of the biggest key factors to take into consideration Can you repeat the scan with the same results Is the anomaly more than on one point When doing the analysis is there more than one measure point to the object If when going over the target with the cross hairs does the target only take one measure point Color Are there many reds oranges and
31. lk and record a scanning path towards the right upper corner of the measure area Different from the parallel measurement you should continue recording data while walking back the second scanning path So you go to the starting point of the second scanning path point 6 and scan in the opposite direction In this way all other paths will be scanned in the scan mode Zig Zag until you have reached the left side of your measure area The distance between the scanning paths should be consistent during one measurement but can vary from measure area to measure area If you mostly look for smaller targets than you should also select a smaller distance between the lines A standard rule is The smaller the distance between the paths the more accurate your scans will be When you are conducting your first scans the lines should not be to close together to locate possible targets 7 1 2 Regulating the length of a scanning path You have to select the length of a scanning path before starting the measurement The bigger the length of the path the more measure values will be recorded and the slower you have to walk the single scanning paths The device stops automatically after the assumed length has been reached and waits for the next path Keep in mind the length of the scanning path which you have selected This amount should be entered later in the software program when transferring the data to a PC to receive all measured data co
