How deep can OKM metal detector technology scan into the underground?

It's not easy to give exact values for depth penetration of metal detectors. This circumstance is not only limited to OKM metal and gold detectors. It's a general problem. One of the most important factors is the used technology. The other parameters are the conditions of the soils and the relation between object size and its depth. This means the larger the buried objects are, the deeper they can be located under the ground.

To get an idea of what is possible with our metal detecting instruments you can find the following depth table with several discoveries of our customers and its detection depths.
