Resulting from eddy currents induced from the metal, a signal is detected when metal is existing. The point that every steel has a different period response when exposed to alternating latest permitted detectors to differentiate between metals. More time waves (reduced frequency) penetrate the bottom deeper and choose for prime conductivity targets like silver and copper, when shorter waves (better frequency) select for reduced conductivity targets like iron.
أي يستطيع تخطي جميع أنواع الصخورالمعدينة بتكنولوجيا المعايرة الأوتوماتيكية.
اجهزة كشف الذهب الاستشعارية بعيدة المدى هي اجهزة كشف المعادن التي تعتمد في عملها على هوائيات ( انتينات) لاستقبال وتتبع اشارات الحقول المغناطيسية الناتجة عن الاهداف المعدنية المدفونة مثلا صندوق مليء بالعملات الذهبية او تمثال برونزي.
