Hi
Qiaozhi,
Your answer is in J_P post.
Why exactly on such especial location we have very very strong signal not anywhere else?and as I've mentioned before in other threads on this location we get strong signal(crazy PD)and with another PI(which is much weaker than MDL) get very weak signals on surface.of course you've forgotten my previous statements about the hot location, MDL gets first signals from more than 50 meters and soon overloads, when reset and step toward it, again soon overloads but for other places with same soil is silent.
Qiaozhi you're wrong, MDL works very very reliable and accurate without any malfunction or error.
our problem with MDL is only when transfer the head inside well, on different times, different behaviors. but on ground surface it works highly stable and consistent.it never gives even one single false signal.
e.g. sometimes ago we took it in a remote place and searched very vast area for about continuous 2 hours. as I said before its' speed is 10 times higher than other PIs.( we can run with that without any problem) it was silent until on one location it got a signal and I led it toward the center of probable target and got the strongest signal just over a flat thick stone.[ first signal was got from 2 meters.]
from signal type I diagnosed target dimension and told to fellows it's small and don't think is worth to dig.
they persisted for digging to see what can be under such stone. it doesn't seem to be a junk. we dug the soil from one edge of stone and finally with another PI found it.depth from surface was about 1 meters. It was a very ancient small iron peak that wooden handle was entirely gone. it was for more than 100 years ago.after that location was without any signal.
When MDL sounds we are sure there is a real target.No man, this cannot justify the exact reason for this specific behavior.
