FE-CO ---The 27 Line? Really?

[Coilfisher]

I read Andy Sabisch's book; used the machine; and now have dug handfulls of targets over the past 2 weeks.
I know what I read about the FE line. 27 being the cutoff.

I can tell you any FE target I dig over 19 turns out to be rusty iron.

What are your experiences?

 

[NebTrac]

I've had good targets at the 27 line, got it on one of my videos even. Its rare and seems to be site dependant and also depth as well. The deeper you get and more mineralization (including iron nails and what not) the goofier your numbers are going to be.


If you're diggin' junk at the higher Fe numbers at a particular spot, then your cutoff line changes (for the most part). Most all of these are 1 way hits, 2 way hits should almost always get dug.

It really is dependent on your ground. As Neb said I got it on video as well. MOST of my deeper coins bounce down into the 20's in my iron mineralized ground. They rarely stay down there though I have dug some coins that do stay in the low to mid 20's and a button that locked on 24 at 8". Got that on video as well. Just check my channel.

For sure Iron in my ground, thus far, is at that 30-35 Fe level.

I think we just have to learn how coins hit in our ground, as you alluded to.

Yesterday I went back to a small yard i have hunted hard before in the standard coin program ( gridded both directions), I used andys program and dug 3 deep wheats and a merc, the merc was a bouncy 19 to 27 but the depth meter was bottomed out and had the silver sound. I thought I had found all that was there in past hunts. Last weekend I dug a merc at 10" plus that came in a solid 27- 43/45, I'm a believer. One thing that has helped me is to use the pinpoint button on those deep targets, if in pinpoint and the box on the screen is in the coin area on the screen it has always been a coin.

I think one time I had a deep merc come in with a CO of over 20, and every other target I had dug over CO of 20 was iron

Curious if the sound clued you on to it being a mercury?

I have to create a new video, edited down, comparing the sounds on good vs. bad targets. The E-Trac really does give a lot of information in the sounds and we use it more than we think we do imo. You have a lot of experience with the E-Trac Goes, could you comment on it's sound in your opinion? Thx,

Sound? Unless it is just me clad and silver sound the same to me on the ETrac (I only have about 20 hours in but I am trying hard to listen).

I know on my CZ-3D I can tell by the sound it is silver. Has a different pitch.

I suppose if you are digging iron every signal above a FE of 20 then just figure it's the lay of the land.
If I prove this contrary at any time I will post, but so far over 19 every target was iron.

So far it sounds the same to me as well (clad and silver). But what I was wondering about was iron and a coin. I can hear a difference there generally speaking. The iron sounds wider and more broken. The coin has a narrower signal and smoother at the top if that makes sense. That may not always be the case, like when the ground is saturated, when the iron is small and round, etc.

Very interesting about your CZ!

I have never dug a coin that had a solid FE over 20 either, but some people have, so I guess you can't completely rule it out.

 

[Coilfisher]

I notice the iron is not as smooth and sweet sounding. A coin is more flutey and smooth than the iron...USUALLY.
I dug enough yesterday to test this out. But, I was fooled enough to dig.

Yes, I thought silver sounded different on the ETrac as it has the multiple frequencies and the like. This was the impression before I bought it.
Was sure this would be the case as I read countless excerpts across the web and including here that I thought it did.
Clad and silver sound the same to me, or maybe just too slight a difference based on my settings to hear.

I have dug several deepies with a fe higher than 27. Here's what I think is happening. Deep non ferrous targets can/will and do give you fe numbers over 20 a lot. But consistent? No. So if your running 20 to 27 fe rejection you may get a good hit. You think well it's a 22fe/46co so it's a digger. But unless you open the quick mask without any disc you won't know if the fe numbers are higher than your fe rejection? This alone will make you "think" that it's a solid 22 fe hit when in reality you will get some higher fe numbers. You will likely see higher than 27 fe numbers that bounce around. So I run a restrictive disc on 30 co and below. Then I open the 30 to 49 co all the way up. This will keep you from hitting the quick mask option because you will already see all the fe numbers. Your results may vary?

Are you saying a number that BOUNCES up to 27 and back to 19 or are you saying consistently at 27???

(I don't doubt your skill as I have seen your videos. Watched yours and several others over the Winter.)

 

[NebTrac]

My video VII Part I is the one I'm thinking of and the numbers never got below 23 on the first dig. Two way signal though and experience at that spot has taught me dig dig any good sound there. I had one way signals with high Fe's turn up good stuff.

Other places (most of the time) it isn't a good target, nails, staples, square nuts and what not. If time allows dig some good sounding one way or 2 ways with high numbers and see what the machines reacting on at that spot and base your judgment whether to dig or not off that.

Take care,

Coilfisher run your variability up to 30 and the threshold pitch to 20 now run a silver dime or quarter under the coil. Sweet ain't it? If I run my gain over 24 I turn deep off. As far as the 27 line goes like some others said if it sounds good dig it. Too many things can affect the numbers. Slow down your swing speed and that will help hear the deep chirps that may be a silver target. It takes about 3 weeks for your taste buds to adjust to something different and longer for your ears to get accustomed to sounds from a new machine. Ferrous numbers are terrible in this TN. red clay filled with iron oxide but having confidence in my E-Trac has made many a good find. Make those settings and give them a try and hopefully you can find more silver or whatever you are after. And watch your cursor. HH

In my opinion, the high fe numbers are circumstantial. Is there iron bleeding, is there high iron content in the soil(imagine Mars!), is there a rusty object next to the target, is my sensitivity too high for this area, is there electrical interference, is my large coil picking up iron fragments? What we are really taking about is wiggle room. Less discrimination, provides more of the overall picture into what is in the ground with it and prevents the nulling(blocking) of good signals.

You wanna have some fun? Take a 5 or more inch rusty nail and then place a silver dime in the middle of it on top of the ground. Then using the etrac stock coil and stock coin program, see how well u pick it up. You should get a decent 1-way signal the other should be completely nulled out.
