Hi all.i am at wedderburn looking for some yellow stuff and today I got a loud signal with my sdc.i dug down about 8 inches and the signal was screaming!then I ran my detector over the dirt dug out of the hole and it went off,I scooped up some dirt and I got a loud signal in the scoop!but nothing was in it!I used my pin pointer and it was going off everywhere.the signal in the hole was making a he'll of a noise just like if you passed over a 22 shell.i have never heard ground noise this definite and loud before.so I'm going back tomorrow to dig the hole.just how noisy can ground get,the soil was red and damp?
