Nice chunk of gold. I am sure that sped up your heart when came out of the ground!!
You said it rang up as a high tab signal. Was that on the f-70? and if so what were the numbers?
HH Ed in co.
I usually post all pertinent technical info about my Fishers in the Fisher forum, but since you asked I am always glad to talk up the great F70.
Short answer...it was a pretty stable 41-43 in the ground, a solid 41 out of the ground.
Really long answer below.
I actually learned some things about gold and hunting in my very difficult soil which is always great to know.
I live in the city of Birmingham close to downtown.
Most parks, curb strips and lawns I hunt usually here in the city were built in the early part of the last century.
My soil is mineralized and loaded with way more iron than you might believe.
Naturally occurring iron, iron slag gathered from iron foundries mixed in with landfill dirt and distributed all over the city as it was being built, this park was built on a landfill and it also has lots of bits and pieces of iron from shallow to deep.
In the suburbs the soil is still mineralized and difficult but it is a bit tamer, here in the city just about everywhere I hunt it is crazy.
So crazy that I have talked to a couple hunters that live here and just never hunt inside the city limits or gave up the hobby completely because of all the iron signals and problems.
That is fine with me, their loss is my gain because I believe I figured out how to hunt in this soil, recognize suspected good targets that are deeper, found settings that can get me deeper into the worst stuff than anyone I know and have recovered a surprising amount of great older targets, mostly coins.
One thing you might or might not know is the the F70 platform, Including the F75 and T2, is designed by the genius engineers to up-average target signals near iron.
I know this is true because a shallow gold ring I found once in great Kansas soil that was sitting between 2 pieces of iron was 10 numbers higher in the ground than it was in air testing away from that iron out of the ground.
According to Keith Southern the deeper you get in heavy mineralization this up averaging stuff also happens even without all the extra iron I am dealing with and I believe that is true, also, from experience.
I tell you all this because when I tell you that deeper coins and other targets come in high around here I want you to believe it.
When I say deep I mean finding coins and other targets around here at the 3-4" area is normal...5" is pushing it but depending on the detector it can be reached.
Getting to 6" is really tough but if you can there are a lot of great targets down there.
So far I have managed to get to the 7-8" range, dug a few great targets from those levels.
Everything past 3" in this bad city soil starts up averaging, every inch you go deeper the numbers go higher, everything I have dug, coin-wise, at the 5-8" area has been in the high 80's to low 90's...Silver dimes, wheaties, copper memorials, Indian heads and even nickels.
I dug a silver war nickel and a V both at 7-8" and they were still in that same high range.
Really deep tabs bounce up to those high numbers too, I have found, and none of those targets are stable and all bounce around pretty good.
I have dug a lot of gold in this state but none in this really bad city dirt and none were ever deeper than 3".so all were at normal numbers.
Since I moved back here and I am concentrating on getting deeper than ever before in this dirt I was hoping to come across some deeper gold and see how it acts.
Will it up average to crazy high numbers, I have no idea but I would like to know.
This pendant was supposed to be at 4" but I think it was more like 5".
It came in a little bouncy in the low 40's and I got it to stabilize at 41-43.
It might have been standing up vertical but I don't know for sure.
I say high tab because tabs start at 46 on the F70 I believe.
Air testing out of the ground it is a solid 41.
In this case gold came in at very close to normal even though it was in the depth area where non ferrous target numbers really start to climb so cool because this really didn't.
I would love to dig a gold ring at the 6-8" level and see how that one behaves.
Everything gets jumpy with skewed numbers past 4-5" here but I figured out how to find deeper coins despite that.
I need practice and data to figure out if I am swinging over deep gold in this devil dirt, I would hate to pass that precious metal by if I can help it, so this one gave me some decent info and I hope to add to that with more asap.
Congrats!!
