I can't speak for other LRLs but in the case of Mineoro one will only want to use a regular MD if he loses the ionic field (real small object) and thus can't pinpont it.
Anyway this should be used as a last attempt due to a EM detector causes the field to vanish. Besides the fact a regular MD will go only a few inches. Totally useless for treasures which are several feet deep.



"WHAT HAS BEEN DONE, CAN BE DONE"
is being driven by a current mirror. Perhaps this linearizes the response of the VCO?
