iron falsing? ver 4?

[calabash digger]

Has anyone noticed that iron sounds better like non ferrous in version 4? Ive been digging way more fine sounding iron with version 4 than I did with 3.2. Ive been running the disc at -2.5 up to -1.5 anyone else noticed this or is it just me? The iron falsing tone seems more smoother in version 4and harder to tell, where in 3.2 its more cut up or forced and you can catch it and call it iron.

Yes I did. that's why I found my self still running 0 Disc. I rather hear them clipping then get a tone from them.

I had a few today that I just couldnt tell on and got frustrated with it . I didnt have that problem with 3.2 it might be the new negative disc ,I need to hear the iron though because im searching for sites most of the time.

I haven't noticed that Calabash. If anything I found the iron easier to identify...... except for that darn deep round iron Maybe it's the negative Disc you are using? I haven't used it yet. I've been running lately all my programs with 3 Tones and with a Disc of 6-8 to while I run a series of comparisons out in the field.

Calabash,

I got my HF coil today and will see if it make a difference on the neg disc. I think that we are going to have to learn the subtle nuances of the new dimensions that XP has programmed in V4. I think it is going to take a few trips out in the field before any of us feel comfortable just like the past versions. As long as we all keep sharing our experiences and thoughts the learning curve of V4 should be fairly short. I think we will start hearing a few Aha's as we get a few more hours in the field conditions across the States. My sites so far have not been over abundant with iron. Maybe I will hit a CW spot this weekend where iron is a premium target. I have a "frag" field that I haven't been to in years. This might be good medicine for this site!

i never liked the high chirp after going over a piece of iron. i like the negative iron sound with v4. its smoother and steadier so i can hear any tone higher then iron better. mahbe try lowering the disc to -5.4 and see if that helps. i haven't heard iron sounding like non ferrous.

One thing I have noticed is that when you get a brief high tone chirp from iron, run the coil over the iron again and it tends to settle to an iron tone now, or discriminate out altogether if running some discrimination. Will have to explore that a bit more tomorrow now that I have noticed it.

Am also keeping an eye on the horse shoe indicator as I could swear some iron was falling onto the non-ferrous side, and I'm not talking about large iron with wrap around falsing either.

Worse junk item so far is pesky zinc roofing metal, that sounds very tempting at depth, though a lot easier to pick out when near surface due to the upswing/downswing in tone and "in your face" response.

thanks will be a few days before I get out again to hunt will report back going to a old plantation with tons of iron will give it a good work out.

Out again today, and my previous suspicions were indeed correct. Checked out several iron targets which came up as repeatable non-ferrous on the horseshoe indicator when discrimination is set at anything below +4.0 (with clear repeatable iron grunt audio), and when set to around +4.0 and above, the same iron targets reverts back to the ferrous side of the horseshoe, once again with iron grunts.

Not sure whether this has something to do with the expanded ferrous range, maybe I am missing something here?? Either way, it doesn't faze me really as I detect purely via audio, though may be a bit confusing for those that rely on the screen for added information.

 

[calabash digger]

believe it or not ive never used the horseshoe either,I don't pay any attention to it as I found all the info in the tones all I need to dig or not dig. The problem is this IF version 4 has changed the audio or how it responds to iron well theres a whole different learning curve.for us who rely soley on the audio. Something is different about it will spend some more time with it and report back. I have a sneaky suspicion its the expanded disc range too.

I have had the same problem with iron. Dug a whole bunch until turned up the iron volume to 3.Only then could I tell it iron from non-ferrrous. Seems like a whole new learning curve for me.

Folks should try full tones,,disc set to -2.5,,,I think this makes nails and iron resemble version 3.2,,, I am using 9" coil btw.

I have done head to head comparisons over nails (undisturebed),,, this -2.5 disc is what I keep coming up with.
Have made some nonferrous finds in an old site too,,,finds that were it seems invisible when using version 3.2.

I did a successful dig this weekend mainly with the hot program. But I briefly switched to another custom program and a shallow rusty nail gave a good non ferrous tone and horseshoe. When I got home I ran the nail under the hot leaving the -6.5, plus all the custom programs I use. The only one that gave the non ferrous signal was the one I had switched to which is similar to your relic program but I had it on 5 tones. When I switched to full tones it reverted to a good iron tone and signal. This is also the only program I have in 5 tones. Think theres a glitch here?

 

[Goldpick]

When I found a decent iron target in the field to have a test on using the HOT program (giving off a repeatable iron audio grunt but a non-ferrous horseshoe indication), I just ran the discrimination up from -6.4 until the the indicated non-ferrous target on the right side of the horseshoe reverted back to the left side again. That seemed to occur around +3.8 to +4.0, which is all a bit strange considering it continually sounded off on the audio as a positive iron target, all the way from -6.4 to +4.0. The iron target wasn't deep either, with a strong audio tone, though not the larger type that gives off wrap around high tone falsing on V3.2.

I do find it strange considering on V3.2 the horseshoe was quite accurate at indicating full or part iron targets, even on say items like brass buckles with an iron tongue where you would get a mixed tone/visiual indication.
The only time it wasn't accurate was on very deep non-ferrous targets that crept into the iron range due to being beyond effective range of the detector.

yep i have the iron falsing as well very frustrating almost reverted to 3.2 but may try some of the suggestions above

I do use full tones and was running the disc at -2.5 up to -1.5 and was having problems with iron . My friend bought a new hf coil and is having it shipped to me to try out for a week or two will see how it does. Ive been on break from detecting so I need to spend some more time with version 4 and see if I can get in tune with it and its nuances. Bass fishing has been getting alot of my time in the last few weeks.

any 10 pound bass ? thats always been on my bucket list. (sorry to divert this thread)
