Find a clear area of ground then set Discrimination to All metal mode, set Sensitivity at about 12 o'clock, turn Threshold knob clockwise until gentle hum. Gently pump the coil up and down, adjusting Ground Balance knob to correct for positive or negative ground (until achieve a single tone).
Well I went onto some new pasture land today - last plowed about 40 years ago. The ground was VERY positive - so much so that even when the Ground Balance knob was turned fully anti-clockwise (before clicking to fixed GB) it was still registering positive ground. This is the first time I've encountered this situation. I decided to leave the Ground Balance knob turned fully anti-clockwise (still manual) and then tune for maximum sensitivity. My question is: Has anyone come up against this situation before, if so what is the correct action - manual GB as far as possible or switch to Fixed GB? Is there anything I could or should have done differently?
I should add that the session went okish - no major finds, a couple of horse harness buckles, musket balls (depth ~7") , a couple of modern copper and a George III halfpenny (depth ~7").

I am not fully up to speed re control boxes being tuned to coils, but it seems if you have a much used favourite coil then its advantegeous to have your box tuned to it. I have also read that tuning your box to the largest coil that you use is a good thing. I prefer medium sized coils generally, so i have the 11x8 coil tuned to my new Tejon, and my 9x8 web concentric tuned to my Trident 2 (UK Vaquero). I have the 12x10 DD and the 5.75 DD too, but just sticking to my general use type coils till i hit a site that requires a more specialised coil.
