F75 found all coins, but one..... A mercury dime on it's side buried 10" inches in the ground.
De mode Preset....6 discrimination
3" dime..yes Clad
6"dime..yes Silver
8" dime yes Silver
10" dime flat yes Silver
10" Edged Mercury no..only in all metal, and only one way read low...58 59 on meter. Was advised it was a very thin well worn Mercury Dime.
All quarters 2" to 12" was loud and clear
Pull tabs at 7" fooled the machine..read as coin 61
Tin foil at 5 inches hit 44 45 depending on swing speed
Bottle caps..some painted so no rust some not 4" to 10" hit every one GRRRRRRRRRRR
Stat mode unable to work in the area..some type of interference close by..
This was not scientific test..Garden has not been dug up in 8 years, so some coins may have risen, depth pretty much read 5 to 7 " on all targets
He has all recorded as to what it is, how far buried, and lined with plastic cylinders. Hope this was interesting to some of you..Just gave me a better idea of what F75 can do...It's not perfect, but when considering how comfortable it is with better than average depth it's just fine...
Forgot to mention all preset except the discrimination taken down to 6, did not raise sens past preset 60...Why..because the preset 60 works best for me most every where I detect..I lower it sometimes but it is preset most of the time..I like the way it works and it goes plenty deep for me..I do sometimes try other settings, but over all De preset seems to find it for me ...even at the 10 disc....
