Okay. Cool. Sounds about right.

I was sweeping in DE a my usual pace picking out obvious targets, then if I got a faint repeatable signal, I switch over to SL and alternate between pin point, and SL using deliberate slow swipes in stead of sweeps if that makes sense.

Found an unreadable Buffalo and a 1930's Admiral Dewey metal play money from the Mazuma Gum Co. in a place I know I've hit a least 2x before.

A few other observations...
If you get something deep that is a bit iffy swinging over it with really fast sweeps seems to give you some pretty accurate info.
I wouldn't hunt that way because you could miss signals you might not notice at high speeds but once you know target locations it seems to work.

Also, certain type targets will not give off correct signals if very deep even in good soil, some up averaging seems to be going on at very deep levels for some reason.
I have dug a few beaver tail tabs at the 10" depth level that came in at just about a dime in solid audio tones and pretty solid numbers in the 70's...fooled me every time and I am not the only one so this is common.
What tabs are doing that deep I have no idea but those parks where it happened in Kansas were old so I had to check them out.
Even though they were trash I was still thrilled I got such a solid signal that deep especially with the standard elliptical, and very happy something was actually down there when I dug the hole.



"What if doing the Hokey Pokey really IS what it's all about?”
F70, F2, Compadre, Mojave, Judge2 - 2017....Clad, 13 silver targets including a freaking Barber quarter, a beautiful walker and two V nickels...
Plus other cool stuff.

----------------Now that happens to me ,hear a good tone ,see that it is the 70s and think -I have a dime-- and the only thing in the hole is a pull tab. A while back I get a sweet tone, in the 70s,pinpoint a small area, this a dime 8-10''deep,out come a full flat beer can.my only thought is how did this get so deep in undisturbed soil.---------Just waiting for AL scrap to go up-----after1----------

My biggest pet peeve. Copper pennies that come in as dimes in the solid mid 70's. Grrrrrrr.

I don't remember if it was in the manual or one of Dave J's essays, but the F70 & F75 were designed with up averaging. I have had my F70 down average, but only in some unique areas.

I now search the old threads authored by REVIER when I have a question or issue with my F70. He and Napa Tom are two of the best "experts" that can give one an answer on these machines.

There are others, but many an issue can be solved with a good search

Yes that up averaging stuff around iron especially is evidently programmed into these things.
A great thing in my opinion.
In good Kansas soil I found a gold ring between two pieces of iron that was 10 numbers higher in the ground than out of the ground.
Not a big deal on that one but when I hunted a super heavy iron site in that same soil all the good coin targets were also about 10 numbers higher which helped me find them.

Here in my crazy southern soil with unusual amounts of iron the deeper you go the higher the numbers.
Everything at 4" or more comes in at least 10 numbers higher than usual, sometimes up to 20 when they are 5-7" in depth.
Even nickels that are deep come in near 90 for some reason.
A silver dollar at 4" was a steady 98-99...something I have never seen before.
As long as I know this I learned to deal with it and it helps me recognize good targets deep around here.

Copper pennies that ring up as dimes are real cooper and well worth digging, as it is the older wheat and Indian pennies that are "real" copper.
Last I heard copper in the penny "copper" penny is worth more than the penny. I have a jar full of Wheat pennies because I dig everything that
reads as a dime, even those deep soda cans or beer cans that give that same reading. Diggim, diggum all I say -- :detecting:

One more thought on this. I have hunted some heavily hunted area where others have hunted and it is really noticeable how the other hunters are
going for dimes and above In one two hour hunt I found 2 dimes and 17 nickles and 32 pennies and no quarters -- guess they were skipping over this
coins or had their disc levels set. Now, get this, on two different hunts in two different states I dug a penny that read like a dime then low grade penny, this kind of
bouncy reading happens from time to time but on these two separate occasions I found the penny over the top of a gold ring. Not kidding, true story. I got the penny
in one dig about 5" down, found the penny and put it away but when I laid my pin pointer down in the hole it kept sounding off. A small gold 10K ring with the
year 1930 stamped on it, right under where I had picked the penny. The other time was in a home town local park and I hit this penny sounding in the 67 range, close to the
surface but it kept reading funny so I figured it for a penny and some trash close by -- out of boredom -- not too many finds that day -- I dug it all of 2" and up popped a penny and a super
nice 18K gold ring with a ruby stone. I dig pennies and I have the sore legs to prove it -- of course I never encourage any of the local boys to dig pennies. One I
dug 211 pennies in a very small area -- no rings that time, but a couple of wheat,

Hello Everyone!!

Well I'm looking for some true setting for gulf coast beach sand. I know that I have had some really good luck with beach sand that is dry but when I get closer to the really wet sands the Machine really goes crazy with a lot of false signals.

Can I get some setting help please. My normal setting are as follows.
DE mode
Sensitivity = 67-70
threshold = -1, -2
tone =3H

thanks for some help here.

There have been some posts out there about this in the past for years.
Tinfoil talked about doing it in this thread with an F75....
http://www.findmall.com/read.php?37,617795,618873#msg-618873

"more then likley you will have to G/B to 0 run sen. at 80 max, threshold to -1 freq at 7 and run it in all metal."

If you are using an F70 the manual says it will GB all the way down to salt but I have never been to a saltwater beach to see and it might not go as low as you need to, anyway.
Everything else you can do regarding the settings above except no manual GB adjustment to get to 0 GB...but there is a workaround.
Ground balance over something to get to that 0 or lowest setting.
A small piece of iron might do it, I have some old red tiles on my porch that can get me there.
Out on my grass I GB'd at 62 but when I brought it up on the porch one pump over it that GB number changed to 0 every time I tried this.
Experiment, find something that will get you there and take it with you to the beach.
I have read of a few F75 users that have used these settings and say they worked.
Maybe not as well as a PI or maybe an FBS machine but for a VLF these Fishers can hold their own, get remarkably deep and still have some respectable results.
I have also read most coils can work but the small DD sniper might work the best overall for the best tones.
Some also have tried multi tones instead of all metal and had good results.
Whether in AM or disc hunting on the beach these ways seems to be all about the tones and not hardly anything about the numbers.
One day on vacation I will try this stuff because I am very curious to see what I can do on a wet beach with my F70.

Another thread here...some say 0 GB might not be necessary and up to 6 or even as high as 12 might work depending on the type of mineralization.
