dr bean ,mate thats pretty impressive with the 2100 shows the older units can still hold their own.
loamer the flat piece was in the middle of a metre square, bare patch of ground in the middle of a well frequented area of surfacing , I can't figure how it was still there
the rounder one at bottom right was about 30 meters downslope from it ,I was heading for a juicy looking outcrop of reef and put the coil straight onto the nug just above the reef ,I think its shed from higher up in the area now surfaced as its obviously(?) well worn , I was really really hoping it shed from the existing outcrop and I could get the crow bar into action! still might bust it up a bit for a look see.
I did test the coil in both the dd and mono mode on the gold and was definetly a clearer brighter signal in the mono, the charcoal and clay domes are a bit of a bother but I'm getting better at recognizing them. good thing is if the signal is harsh I can flick back into dd and test the discriminate which works great on shallow ferrous.
thanks for the feedback and encouragement
cheers , flash
