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.
This effective Metal Detector with an enormous detection capacity is designed for a wide range of users including archaeologist, relic hunters and professional institutes because of its low cost. You can hunt for coins, relics, jewellery, gold, and silver just about anywhere, check metal in post package baggage, detect underground pipe, etc.
Awesome detection for large objects and coins in depth! Shaft length is adjustable for comfortable use.
