1. Detection depth of underground treasure hunter:
Generally speaking, the larger and heavier the area, volume and weight of gold, silver and copper, the deeper the high-precision underground detection depth of the metal detector will be.

2. Specific functions of underground metal detectors:
The handheld treasure hunter of the metal detector can accurately determine the buried location of the object and can locate it.
The handheld metal detector can also rely on the frequency regulator to identify the specific type of metal.

3. Detector product parameters:

1. The metal detector underground treasure hunter has a built-in demagnetization function (as long as the receiver probe is close to the iron metal and the alarm sounds three times, it can be demagnetized)

2. The treasure detector underground treasure hunter has a built-in signal-enhanced receiving antenna inside and outside, which can easily receive signals

3. The search range of underground metal detectors for gold, silver and copper: 100 meters (for veins and small objects, the search range of security detectors will be narrowed and closer)

4. Scanning depth of metal detector: 15 meters, test positioning standard, half a square, 3 mm thick copper block

5. Scannable metals include gold, silver, copper, and gemstones with high metal content. Other metals cannot be detected.

6. Weight: 3.2kg Packing size: 35*14*32cm

The 3D treasure detector high-precision visual gold and silver model is equipped with a display screen, which can display the surface situation, making it more convenient to check at night.
