Frequency Metal Detector Removes Rusted IronThe power and ability to remove interfering particles of useless fields with the frequency of the radar circuit with high abilityFrequency Metal Detector or any type of Metal Detector Image Scanner or GPR or ground handy radar or Ground Penetrating Radar or antenna metal detector (or long range locator) that has VDI number settings in Edit and threshold level and Size and other settings according to the low frequency or multi frequency Radar circuit has the power to remove rusted iron or interfering particles formed from useless fields with interference and one of the factors in such conditions is the proportion of frequency movement in the movement of positively charged particles of frequencySource of books by the scientist of electronic sciences of radar Ramin Keykhosravi with permission
