It seems this is the advice everyone gives, dig everything with a good tone or else you will miss some "goodies". So lets discuss what constitutes a "good tone". Based on my brief experience and what I've read a "good tone" means a repeatable tone. A tone that doesn't change when you circle around it. Clearly a "good tone" has little to do with the associated VDI #'s. With my F4 VDI numbers are a guideline only. Even in just the few months I've been digging I've seen clad pennies at various VDI's and the VDI's jump a bit. Same for wheaties, they have quite a range. Dimes and quarters on the other hand do seem pretty stable at any reasonable depth.
SO lets start a list of attributes of a good tone, please help me add to it:
1) Repeatable as you circle them
2) Tone may jump here and there, but is stable in at least one direction.
3) Pinpointing doesn't make the object appear too large.
4) It just "sounds right"
What else???
Regarding "just sounds right" its like my Mom teaching me to make pie dough, "add a little water, keep dusting it with flour and knead it until it feels right......
