Thanks for the reply mate. Completely agree with you. I was hoping to get a general depth idea for any given area. However I suppose it varies greatly even in the same field.
Yeah those sdcs are dynamite. If you could put a small coil on that gpz you'd be getting the small stuff as well. Hopefully down the track.
The sdcs excel in the hot ground where my 8" goes spastic. However on the heaps they are very comparable unless its a particular shape that one machine prefers over the other.
Got another 2 small nugs today with the 8" in a new area. The SDC 4500 strikes again haha.
