You must have permission to search both private and public property from the owner or person responsible for managing the property but start with your own yard where valuables can be found anywhere people gather, anywhere they lived before 1965 likely to contain patterns of old coins.
The size of the search coil can affect the depth of detection or the sensitivity of the metal detector. The larger the disk, the deeper it will detect, but it will be less sensitive to small targets. On the contrary, the smaller the diameter of the search coil, the higher its sensitivity but loses the depth of detection. Small discs are lighter, easier to control, and can be selected for their ability to overcome tough terrain or bushes. It is also considered an advantage in high waste areas.
On some detectors, you don't need ground balancing at all. In other cases, users who are new to detection are advised to use the ground balancing tracking function. In tracking, the detector will automatically balance the ground for you and stay in equilibrium even if the ground minerals differ. In manual ground balance detectors, you need to ground balance at the start of each search and rebalance periodically as required.
Gold chains are very difficult to detect, especially very fine chains. Each link in a chain can be very small and the detector sees each link as a separate target so that it can be easily missed but high-frequency detectors often detect delicate chains better than most coin detectors.
