In a supposedly hunted out park near the edge that had more EMI problems than any site I had ever been to before or since I rolled over this coin spill that was reported to be 7-8" in depth but at least one or two of these coins were closer to 9-10".
4H, sense on 80, -1 on the thresh using the F75 DD coil I got a pretty jumpy signal because of that EMI, ( no DST on mine), but most of the numbers stayed high and I kept hearing a repeatable sweet high tone as I maneuvered the coil around the area.
The deep depth and good tone made me curious so I opened a hole and found these coins spread around about a one foot square area.
A 1915 wheat and three injuns.
In that same area on another hunts still with that huge amount of EMI and that coil I also found a very masked merc in the entrance to this 100 year old park which was filled with a huge amount of trash.
I did it by turning down the sense to about 30 as I mentioned and this thing sang out loud and clear and repeated at about 5-6" like it had a red flag over it that said dig me printed on it.
On another hunt in that same problem area I found a gold ring sitting nice and pretty between a deep piece of iron on the right an inch or two away and a smaller rusty iron nail on the left also about an inch or two away.
I got a mixed jumpy signal from high to low because my coil was over all three targets at the same time but as I swept the coil over the area from left to right and back I realized after pinpointing there were three targets here but the middle one gave me a nice tone and repeated some 51-53 numbers, they were fleeting but kept repeating so I decided to dig it despite thinking it was going to be trash.
Surprised the heck out of me when a gold ring popped up and I was lucky I hit it from this angle where the superior target separation Fishers possess alerted me.
If I hit these three from a 90 degree angle I think I would have gotten a whole different signal so never discount luck in this business.
This is important so take note...this ring out of the ground dropped a full 10 numbers to a solid 41 and this is because Fishers are programmed to do something that you can use to your advantage if you understand what us happening.
They up-average all targets around iron in infested sites or on deeper targets if you hunt in mineralized ferris oxide infested soil like the red clay I have in my neck of the woods.
I mean they can soar on gold, silver, tabs, coins...everything.
Remember this if you hunt in iron.
In a site so infested with iron in good Kansas soil where many tried but nobody made any headway, including me, and most gave up and looked for easier sites to hunt I stayed and hunted it many times looking for any way to unlock this iron puzzle and get to hidden and masked targets we all suspected were there but couldn't find.
It took hours of experimenting but finally I hit on some settings and noticed behavior that helped me figure it out and that up-averaging effect was a big reason I was able to find all this.
Here is just some of the bigger stuff I had to deal with, I don't have a picture of the million nails, nuts bolts wire and everything else that were here.
Here are the better targets ultimately came out of this very difficult site.
In my current SE. Alabama devil dirt I have been able to find several great targets from some scoured sites long ago given up on and declared hunted out but I found out they weren't...this up averaging thing helped me find these things that were severely masked from the 4-8" depth level.
They were here the whole time but it took my up-averaging Fisher to find them especially the deeper ones.
Nickels here, you know the 31-33 VDI signal will actually come in at the 50's-60's zinc area if at about 4"...I have dug buffs, older Washintons and a V nickel here from the 6-8" depth area and every one came in from the high 80's to low 90's.
Like I said around iron signals can and will soar high.
The absolute deepest target I ever dug was a thumb ringer off of an old bicycle bell.
In disc with maxed out sense, (and thresh which I can do on the F70 but you don't have that option), I got a solid signal in 1F from several directions and good tones plus pretty accurate VDI numbers which is unusual for something this deep...an actual measured 15".
At the very fringe of the detecting field you might hear a tone but the screen will usually go blank.
This is normal on super deep targets and when I got the good tone AND the screen info and a 14-15" depth reading I had to dig it just to see if anything was actually down there...and there was.
Not a great target but still shocked me that it could see it and tell me it was there.
