My questions now, can anybody tell me where are come 5 khz ?
How it calculated?
why don’t using 10 khz or 15khz or other range of frequency?
What is relation between this frequency with materials resonance frequency ?
Anybody know This relation formula ?
Regards.

MFD works very good with small and new buried objects. So it was easy to see at who frequency it works better for the gold... silver etc. All the guys that i know they use the 5000..... 5100 frequency for the gold (they say that it is more sensitive), but why between some manufacturers there is difference frequency?????? i don't know
