I want to buy a Fisher Gold Bug-2 or other similar metal detectors can find gold nugget. Are there metal detectors is that retail gold in the rivers.Please advice.
Yes, there really are detectors that can find gold in the rivers. If you are looking in a dry riverbed, then you won't need a waterproof coil or box. If you are detecting underwater, you will at least need a waterproof coil. If you are detecting fully submerged, then you will need one that is completely waterproof, and most of them are not dedicated nugget machines.
