QUESTIONS & ANSWERS
Ask a Question-
What depth through soil can it detect
This question we hear a lot and its an important one. The short answer is that there are many variables that can affect the depth of metal is detected. VLF (very low frequency) hobby detectors can detect various depths depending on the ground conditions and target size. However, it is known that the size of the coil is usually how deep it will detect. For example, if you have got an 11-inch coil, it will typically detect at a depth of 11 inches.
