What metal detectors should be equipped; Reference of technical data provided by Shenzhen United Huayi:
Underground metal detector copper coin underground metal detector gold silver dollar underground metal detector jewelry underground metal detector application field:
1, search for coins, jewelry, gold and silver jewelry.
2. Underground detection of gold and silver treasures and metal cultural relics.
3. Detect underground scrap steel, steel bars, copper wires and other metals. The maximum detection depth is 5 meters.

HY4900DJ metal detector operates like an engineer detecting mines. During detection, the probe keeps a distance of 10- 15cm from the ground and moves in parallel on the ground. Don't lift the probe too high, so as not to reduce the actual detection depth.
Adjust the identification knob according to the specific situation and eliminate those unnecessary targets. For example, a waste nail is detected in many places, and there are signals of nails everywhere, which brings great inconvenience to the detection work. In this case, you can put a nail on the ground in advance and let the probe pan sweep the nail. If the sound of the instrument increases, press the button, turn the "Work Adjustment" knob to the left (counterclockwise), release the button and detect again. If the sound weakens, also remove the probe, press the button, turn the "Work Adjustment" to the right (clockwise) and release the button. After adjustment, buried nails and ferrous metals smaller than nails will not increase the sound of the instrument, while non-ferrous metals and ferrous metals larger than nails will make the instrument make a lot of noise. If the recognized target is a ferrous metal sheet, a special phenomenon will appear: when the probe moves near the edge, its response is the same as that of ferrous metal, but when the probe is facing the center of the sheet, its response is the same as that of non-ferrous metal.
Detection tip: Try to avoid swinging the probe to detect when using the instrument, otherwise there will be reading errors. It is best to form a sweeping arc with a width of 15 cm from one side to the other and keep it parallel to the ground. Slow-moving scanning speed may be lost when detecting targets.
Matters needing attention
1. If the instrument can't work normally and the sound can't be reduced after increasing, it means that the battery is low and should be charged in time.
2. Don't press the button on the metal. Press the button on the ground without metal. You can't hold down the button when testing.
3. If the instrument can't keep the "critical tone", it means that the instrument is faulty and should be sent back to the company for maintenance.
