Metal Detector / Treasure / Model 89MC

Electronic instrument of high precision programmed to work in projects of engineering or planning assitence widely used to detect pipes or metal objects buried in shallow or deep grounds. Using modern technology and projected for continual use, the model 89MC is the most up-to-date device in the field of finds buried metal objects.

Used by Government Departments, industries, private and public companies, mining companies, planning assitance, assistance and maintenance of nets of sanitation and sewers, Armed Forces, Civil and Military Police, customs control, Embassies and Consulates, minimo engineers, Universities, etc.

The "TR" detector works at low frequency (LW) avoiding this capacitive effects and high sensitivity.

The detector model 89MC represents the newer and most modern device in detecting pipes, connectios, valves and distribution boxes, etc.

IT WAS PROJECTED TO FIND WITH ACCURACY THE VERY PLACE OF METAL OBJECTS AND PIECES BURIED AT MEDIUM AND GREAT DEPTH.

Entirely electronic, build with transistors of epitaxial tecnique with silicon, providing high stability in the handling. the internal speakers with medium power and the external phone make this process even easier, offering to the operator more comfort in the diagnosis and high control when marking the detected center.

Total lack of capacitive effects, because it was built in aluminium and uses a single feeding source for both parts: Transmissor and Receptor. The model 89MC doesn't suffer the influence of what is called of "negative detection" wich forces in many cases the final diagnosis, provoking some interpretative errors. His action area is very low for big objects.

The 89MC does not have a side action area, registering only in vertical direction. This is very important when there are many metal objects around which might provoke this side action records. This model 89MC does not have this problem. the records are registered only in vertical direction from the receptor sensor, with accuracy, facilitating the exact marking of the place.

It is appropriate to detect metal gloves, junctions, ends, tees, reductions, caps, registers, etc., The metal detector model 89MC works with high sensitivity through conductive system.

Used with sucess in many countries, in services of planning assistance it is among the detectors models, one of the more sesnisitive manufactured at present around the world.

The mesurements presented in this chart were executed in grounds lacking minerals. In the case of zones extremely or medium mineralized the chart will suffer some decrease in the figures.

Yet in areas with no or little electro-magnetic fields, the percentages of the charts are accurate and will be somehow increased. The number were registred for 25% micro-amperimeter deflexion.
