FIELD TEST OF METAL DETECTOR TREX® 204 M Dzafer Kumbara The new metal detector TREX ® 204 M was tested from the middle of April by local EOD (explosive ordnance disposal) officers in Orasje, Bosnia. The following results became available at the end of June: First of all it was investigated whether the detector would meet the requirements of humanitarian land mine detection. The UPMAH-3 was used as reference object. This was buried in a test bed and had to be detected at various depths and with commonly used probe detection speeds over the ground. Depth Detection speed Indication 10 cm 0.3 m / Sec. yes 13 cm 30 cm / Sec. yes 16 cm 30 cm / Sec. yes Satisfactory test results were achieved with medium detector settings in respect of mineralized ground and the sensitivity. The detector was then used every day by 16 different EOD officers. The conclusive impression was good. The convincing features were: That it was lightweight, that the location of detected objects could be determined precisely and that the device could be operated very fast and easily. The search coil, which looks like a hockey stick, is perfectly suited for use in dense vegetation and high grass, among rocks and under undergrowth. It provides the safety necessary for EOD officers to progress their work rapidly and easily. When used on the damaged parts of buildings, holding the detector head into the cracks before removing rubble also helps to ensure the EOD officers‘ safety when working. The alarm signal helps in differentiating between large and small objects and whether these are at low or great depths. The inspector (supervisor) found that the productivity with the TREX ® 204 M was 11 m 2 in half an hour. This is equivalent to a performance of 110 m2 per day. No other detector could reach this level of performance! The detector does not work when used close to electricity cables buried in the ground. This is indicated by a continuous alarm signal with several stops. On the other hand the device functions in a proper and undisrupted manner when used near high-tension (power) lines with high discharges. A total of 21 antipersonnel mine fuses could be detected in a very precise and reliable manner on 11.05.2010. Additional fuses of the same type have been detected at a depth of 15 cm under vegetation. On the following day we detected further fuses in the beds of bombed greenhouses with the same level of safety. 14| ebingernews It has to be noted that mineral fertilizers had been used in the past and this had led to the ground being highly mineralized. The TREX ® 204 M was not affected by this. On 17.05.2010 it was operated with modified ground compensation settings on a non-cooperative mineralized ground. The conclusion of our EOD organisation is: All safety requirement and work quality parameters were met by the use of TREX ® 204 M in the mine field. The slim hockey probe offers a lot of advantages when used under dense vegetation. The speed at which small and large objects can be detected and their position indicated as well as the depths at which detection can be achieved are satisfactory. In contrast to other detectors pinpointing was possible. The alarm signal enhances productivity and helps to avoid crucial failures. TREX® 204 M on highly mineralized non-cooperative ground The detector has been tested in Herzegowina at the Suva Smokva Nr. 8 location, which is part of the organisation N&N Ivsa from Orasje. After the pre-inspection of the field by another modern detector, the TREX ® 204 Mwas used for quality control. The test results obtained were as follows: The test took place on 18.06.2010 starting 6 a.m. The humidity was very high and the temperature was around 18°C. The test started with the examination of a fuse whose holder was located 40 cm above the ground. The pre-inspection included: - active detection of fuses at a depth of 10 cm (13 and 15 cm) with a speed of 0.3 m per second with elevated head The next detection field included the examination of buried fuses. In this case a continuous alarm was obtained with a medium sensitivity and ground compensation setting. Accordingly the settings for sensitivity and ground compensation were adjusted until the ground interference was suppressed. It has to be noted that for this the detector had to be switched off and then on again. This meant that detector adjustment took around 30 to 45 sec.
After adjustment the detector was in operation for around one hour in the field which had been already pre-inspected by another standard detector. During the work neither unknown alarm signals nor rustling alarms were noticed. On the control field an alarm signal for an object at a depth of 12 cm was received. This object had not been detected by the standard detector. The detector was used in rotation – i.e. one hour operation – one hour break - without being switched off. In the time from 6 a.m. to 2 p.m. the temperature increased from 18 °C to 32 °C and the humidity decreased so that the detector was working under normal conditions in the active detection work during this period. After a preliminary audit the detection work was started on 19.06.2010 at 6 a.m. on a mine field which had not been inspected before. The detector was then in use for around four hours. During the preliminary audit the emphasis was placed on a constant detection speed of 0.3 m per second and with the head positioned close to the ground. The detector was not switched off during this period. The report states that during the above time 6 PMAs (2 of them contact mines) were detected at depths of 3 – 8 cm. These were indicated by clear and strong alarm signals. PRODUKTINFO TREX® 204 M Das TREX ® 204 M ist eine moderne Variante der bereits vor 40 Jahren in der Kampfmittelräumung erfolgreich eingesetzten EBINGER-„Hockeyschlägersonden“. Das neue, weiterentwickelte Sondenkonzept des Typs TREX ® 204 M (akkreditiert durch BH-MAC) gestattet eine genaue Lagebestimmung von Metallobjekten, die in schwer zugänglichem steinigem Gelände, in Furchen, Löchern oder im Unterholz verborgen sind. Auch unter erschwerten Einsatzbedingungen schätzen Anwender diesen Detektor aufgrund seiner hervorragenden Sucheigenschaften und der guten Laufruhe auf mineralisierten, bedingt kooperativen Böden, was von Minenräumern sehr positiv aufgenommen wird. In der humanitären Minenräumung unterstützt TREX ® 204 M das Aufspüren von oberflächennah getarnt verlegten Landminen mit geringem Metallgehalt. Blindgänger, die je nach Kaliber und Suchbedingungen in der programmtypischen Suchtiefe von 50 cm verborgen sein können, werden ebenso erfasst. Typische Suchaufgaben, die bei der Polizeiarbeit oder auch in der Archäologie und Geologie zu finden sind, werden durch die präzise Lokalisation und klare Signalgabe deutlich erleichtert. PRODUCTINFORMATION TREX® 204 M The TREX ® 204 M is a modern variant of the EBINGER „hockey stick probe“ that was first put to use for the detection of explosive ordnance 40 years ago. The new and further developed probe concept of the TREX ® 204 M (as accredited by BH-MAC) permits a pinpoint location of metal objects which are concealed in stony terrain that is diffi cult to access, in furrows and trenches, channels or beneath under-growth. Even when used in adverse working conditions, users cherish this detector because off its outstanding detection properties on mineralized and only partially co-operative ground and good balance. In humanitarian mine action the TREX ® 204 M supports the detection of landmines with low metal content concealed close to the surface. ERW which is buried down to 50 cm, can also be detected depending on size and local working conditions. Typical search tasks that arise in forensic police work as well as in archaeology and geology are also significantly facilitated by the detector‘s pinpointing properties and clear signals. In addition the wires of a PMR 2A mine were able to be detected under the grass / vegetation. After the wires had been tracked for 4 - 5 m, the seventh mine could be detected 2 m next to the wire at a depth of 10 cm by a clear and strong alarm signal. The detector was then used for two further days in accordance with the procedure described above. The same SAFE results were obtained. At the end of the week the battery control lamp came on indicating that the battery needed to be recharged. In conclusion it can be noted that operation with the detector was satisfactory in all respects in spite of the high mineralization of the ground, the high initial humidity and the unstable weather conditions. In addition it has to be noted that the TREX ® 204 M was able to function properly near high-tension power lines (35 kV) while other detectors could not. ebingernews | 15
