3D ground scan detectors are best in detecting ferromagnetic objects, but this is not a limitation. Due to high sensitivity and environmental situations where the gold or precious treasures are places, these metal detectors can be the best choice for professional treasure hunters.

 

Disseminated gold, placer gold deposits, or natural gold and veins in consolidated soil can be easily detected by the detector since they are associated with mineralized zones that also contain magnetite or other magnetic minerals. Solid gold can be detected only if it is buried in soil that normally contains a small amount of magnetite or magnetic material or it is placed in a chest or other metallic box.

 

Magnetic holes that are in most cases created by a man when digging a hole at any specific location on the Earth’s crust cause anomalies in the magnetic signatures that can be easily detected by 3d metal detector. Such holes often hide gold or other valuable objects.

 

In other words, classic metal detectors are much better when the goal is to find a single coin buried up to 30 cm under that sand on the beach or discriminate between different metals, while 3D metal detectors perform better when users seek bigger treasures that can be buried way deeper and non-metallic objects (placer gold deposits, chests, caves, tunnels, caverns..) that cannot be found by classic metal detectors, but in many cases hide gold or other precious treasures.

 

Treasure detectors determine object material and gold with the shape and color of a 3D ground scan. So we can determine if an object is ferromagnetic or not. If it's not it's a good chance of gold detection. For example, if the 3D ground scan is mostly positive RED or YELLOW color it's good indicator of non-ferromagnetic materials.

 

If the object is not ferromagnetic (gold, silver, aluminum) positive signal with a small chair below the peak of the signal. It is a good indicator you have detect the Gold target.
