The detector operates at the Very Low Frequency (VLF) 6.6 KHz which gives accurate detection. With the VLF the detector only responds to metal objects but not the effects of iron ground mineralization. Different discriminating circuitries allows the detector to distinguish metal objects between different types of ferrous (iron and steel) and non-ferrous metals (gold and silver). The powerful super sensitive Discriminator Metal Detector with waterproof coil provides you an underwater detection up to 200mm.
