If you are dealing with highly mineralised variable ground you will need a Pulse Induction (PI) detector.

A member of this forum made an excellent video of a talk he gave on how VLF and PI detectors work, only I have lost the link.
Even with a good PI detector and a Mono coil you still occasionally dig hot rocks and false signals in very mineralised ground. Using a DD coil helps.
