Hi JW
The area I work is mineralised ground, I can get away with High Yield/ Normal that's usually my go to when I start.
I auto ground balance with the ferrite, but I should check the ferrite balance more often.
I try to keep a clean smooth sweep action, I didn't use the swing arm at first but i did last time i went out and it does make detecting easier.
I have tried steves insanely hot settings, bit odd at first to be "in the dark" i wouldn't detect like that all the time but maybe on mullock heaps?
Your a champion JW thanks heaps for the help, i cant wait to get out this weekend and get on the hunt
