| Yesterday I went hunting in an area where in the past all the waste coal cinders were spread out on the school lawn. This material causes my F75 to chatter only when the coil is in motion. Reducing sensitivity and increasing discrimination doesn't seem to help. Changing frequencies had no effect on the amount of chatter. But changing to the AM mode allowed me to pull 5 rings and several coins from an area that I had hunted extensively over the past 4 years with both the Tesoro Vaquero and Tejon. I did some test each time I found a good target by switching to disc mode and adjusting down to 0 with other setting combinations. Most of the time in discrimination mode the target either disappeared or became erratic in the audio response. Some of the targets could be heard if I would lower the discrimination down to 0, but there were two times where even at 0 discrimination the target didn't give a good enough response to prompt me to dig. Hope this helps. | |

That reminds me of an experience where I learned something.
I was inspired by someones post about hunting a high school
gravel parking lot. I know that most of my gold comes from
younger women. From high school on up. So I decided to hunt
where tha high school kids park during school.
Tha gravel is like SB2. It packs hard. Thay use it as a base for
paved roads.
As soon as I started, I realized that tha rock that this gravel was
crushed from is highly mineralized. These are what some people
call hot rocks.
I burried a quarter under 3? of this gravel and could not get a signal
in tha disc mode.
The only way I could ground balance my Euro Sabre was to burry
a penny about 1? deep and swing tha coil across it, at tha same
time, turn tha ground balance until I could tell tha difference between
tha target and tha gravel.
That seemed to work alright. I could still get small targets, even
in tha "Gravel From HeII".
Every now and then I could even detect things below tha gravel.
That is how I found this old brass lock.
But it was really hard to dig so I mainly concentrated on shallow
targets. Here is what I found.
I even got a signal on this tiny gold chain, I could not get tha
knots out of it. It was squashed anyway. Tha gravel is rough
on stuff.
A squashes brass ring. I think it was silver plated at one time.
It was cold, windy and spittin rain. When snow flakes started,
I quit.
I learned something at my parkin lot hunt,
