My 700 arrived last night. Had some time at lunch to swing my best site for about 45 minutes. Park1, Sensitivity 21, Ground balanced and Noise canceled. All settings stock.
This site is 1750 to maybe 1810, zero modern trash. Found state coppers and many buttons here. Everything is deep here and lots of old iron in the ground.
The detector ran very smooth, but kept locking in on 91-96 signals swinging in multiple directions. First 9 targets were crusty bits of iron, one iron spoon handle, a couple small 25-28 signal targets that were very small pieces of brass or lead and then I dug one more of the deep 91-96 signals and popped out a clod of dirt that dropped to solid 61/61. The etched tombac button.
Any idea why the sweet deep high tones are prevalent? Do I need to adjust the FE settings?
