Most gold detectors cannot search very deep into the ground because small gold nuggets won’t lie that deep in the soil. In the natural environment, you shouldn’t have to dig too deep to find small nuggets of gold, which means there is already a limit established. For some gold detectors, this will suit their needs and wants.
To give you an idea of depth, a gold nugget that is half the size of a grain will normally be found about two inches deep. A gold nugget the size of a match head may be found as deep as five inches and really large pieces of gold could be found deeper than a foot or more using Pulse Induction Technology. Ultimately, the size of the nugget will correlate to how deep it is found and the larger the nugget, the deeper it will be buried.
If you are a gold hunter who is out looking for large pieces of gold like bricks or you want to find hidden treasure chests, you will need a different type of detector. For deep seeking gold hunting enthusiasts, a two box metal detector should go the depth you need to find buried treasure. These types of detectors won’t find small pieces of gold but could possibly find large amounts of gold or silver that has been buried deeply in the ground.
