Page 6: General Application
Along with its digital signal processor the metal detector uses the function principle of an advanced pulse-field specially improved by Vallon. It can work also in strongly mineralized soils, like laterite, magnetite, magmatite as well as in shallow water (salt and fresh water) and under the electromagnetic influence of main power lines without affecting the detector’s sensitivity too... - Page 7 For detection of mines of other manufacturers it is recommended to test in advance whether they are detectable before the operator starts the detection work.
