3rd hunt with E-Trac nails drove me nuts! I was hunting at an old house yesterday using the Minelab coin program and the nails were sounding just like silver and the numbers were good as well. Do you guys have any suggestions on how to best make a determination on nails? Thanks for any suggestions- Randyhttp://www.findmall.com/read.php?71,1381711,1381711#msg-1381711Mon, 20 May 2013 16:27:30 -0500 Phorum 5.2.18 http://www.findmall.com/read.php?71,1381711,1775868#msg-1775868 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1775868#msg-1775868
If iron falsing is occurring turn down the +3 Auto Sens until it disappears, perhaps -2 Auto. You aren't going to lose much depth since iron spreads out the EM signal and does a tremendous job of decreasing depth on its own right. So, go ahead and reduce the sensitivity.

Overpowering the nail head and nail tip with circulating eddies will give those high chirps that sound somewhat like non-ferrous coins. Normally an iron nail is all reactive signal and is easily disc'd out by detectors. But when they are bent or have sharp edges the resistive signal can impersonate the non-ferrous target.

Also, turn Trash Density to High - it will help lock on the good accepted signal letting it through and block out the less consistent signals.]]> Johnnyanglo Minelab E-Trac Classroom ForumMon, 10 Sep 2012 20:03:26 -0500 http://www.findmall.com/read.php?71,1381711,1687704#msg-1687704 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1687704#msg-1687704 Damar2003 Minelab E-Trac Classroom ForumThu, 26 Apr 2012 17:05:22 -0500 http://www.findmall.com/read.php?71,1381711,1682240#msg-1682240 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1682240#msg-1682240 stasys Minelab E-Trac Classroom ForumWed, 18 Apr 2012 03:02:19 -0500 http://www.findmall.com/read.php?71,1381711,1678252#msg-1678252 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1678252#msg-1678252 EtracTom-AdirondacksNY Minelab E-Trac Classroom ForumThu, 12 Apr 2012 10:28:39 -0500 http://www.findmall.com/read.php?71,1381711,1668926#msg-1668926 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1668926#msg-1668926

Having your gain set too high will cause iron falsing? I never thought about that. Will back the gain off to about 20 and see how that works.

Yes, it is probably the number one user induced cause of falsing imo. I say "user induced" as when the ground is wet it happens even more (in my ground.)
Just drop your auto+3 down until the falsing seems to go away. I guess you could test this on target you come across in the field to keep the depth optimal.

I run manual even with the falsing. As you learn the unit better the falses stand out more, though I still dig deeper iron nails on occasion, but also pull deeper coins in iron ;-)]]> earthmansurfer Minelab E-Trac Classroom ForumWed, 28 Mar 2012 15:55:22 -0500 http://www.findmall.com/read.php?71,1381711,1658420#msg-1658420 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1658420#msg-1658420

Yes I have Trash - High and Ground - difficult on. I did modify the basic coin program based on suggestions from an E-Trac user. Here are the settings.

sensitivity auto +3
threshold limit just barely audible
volume limit 29
volume gain 29
response normal
tone id multi
sounds conductive
variability 29
limits 29
threshold pitch 28-29
deep off
fast on
trash high
ground difficult

Gain set too high for conditions/area you were hunting......=Iron Falsing.........]]> M-scope Minelab E-Trac Classroom ForumMon, 12 Mar 2012 21:12:20 -0500 http://www.findmall.com/read.php?71,1381711,1654498#msg-1654498 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1654498#msg-1654498 SwampeR Minelab E-Trac Classroom ForumThu, 08 Mar 2012 18:01:05 -0600 http://www.findmall.com/read.php?71,1381711,1637620#msg-1637620 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1637620#msg-1637620 lawsonland Minelab E-Trac Classroom ForumSun, 12 Feb 2012 11:23:17 -0600 http://www.findmall.com/read.php?71,1381711,1625126#msg-1625126 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1625126#msg-1625126 MHirschmann Minelab E-Trac Classroom ForumTue, 24 Jan 2012 00:02:03 -0600 http://www.findmall.com/read.php?71,1381711,1622950#msg-1622950 Re: 3rd hunt with E-Trac nails drove me nuts!N/Thttp://www.findmall.com/read.php?71,1381711,1622950#msg-1622950(This message does not contain any text.)

Only way to check to make sure they are or are not iron targets is to use quick mask to open up the screen, this way you can see the sounds/cursor and it will remain more consitantly in the iron range.]]> EladSwerdna Minelab E-Trac Classroom ForumWed, 09 Mar 2011 12:19:19 -0600 http://www.findmall.com/read.php?71,1381711,1404114#msg-1404114 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1404114#msg-1404114
I will normally turn on the Quick Mask screen and pass my coil over the target, Normally trying to keep the movement of the coil no more then two inch's and will do it as I turn completly around the target. If the courser (target box) stays in the lower right corner of the screen I have a piece of iron and I move on. If the target box stays in the mid section of the screen and gives me a good Target ID I am digging. If the target box wants to jump from the center of the screen and back to the lower right corner and back again I know I have a good target with a piece of iron interfering with it and I will dig it. I have repeatedly dug coins and tokens with nails laying across or close to them doing this. It really works good for separating good and bad targets and helping know when to dig.

What I found works is during pinpointing a nail will pinpoint off from where it sounds in motion mode. When you get a signal from a nail it comes from the point, but when you pinpoint the strongest signal will come from the nails head. So when you pinpoint and the target seems to move chances are it's a nail. Especially if you rotate 90º and the targets pinpoint position moves. Dead giveaway.

Good advice eventhough sometimes I forget and dig that nail too! :wacko: here is a bit of advice I got from my friend Nick who has taught me a lot.

Another trick of the E-Trac and Pro coil is that reliability of a signal that repeats at 90 degrees is almost always something round. It may be a piece of round iron fooling you, but the detector loves things that are round. I've dug plenty of signals that did not repeat at 90 degrees, but more often than not, a signal that repeats the same (or close) at 90 degrees is worth digging. Sometimes if I like a signal but can't get a 90 degree repeat, I'll shift the position of my original scan by 30 or 45 degrees and then see if I can get a 90 degree repeat from a new angle. There may just be a piece of trash that's blocking me from getting that 90 degree repeat from my original scan.]]> Bell-Two Minelab E-Trac Classroom ForumSat, 29 Jan 2011 11:14:47 -0600 http://www.findmall.com/read.php?71,1381711,1389936#msg-1389936 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1389936#msg-1389936 Southwind Minelab E-Trac Classroom ForumFri, 28 Jan 2011 13:33:57 -0600 http://www.findmall.com/read.php?71,1381711,1389925#msg-1389925 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1389925#msg-1389925 EZrider Minelab E-Trac Classroom ForumFri, 28 Jan 2011 13:07:35 -0600 http://www.findmall.com/read.php?71,1381711,1382059#msg-1382059 Re: 3rd hunt with E-Trac nails drove me nuts!http://www.findmall.com/read.php?71,1381711,1382059#msg-1382059
Another option is to try 2-tone Ferrous. I've seen several posts from others that swear by it when they get into an iron infested area. Do a search on this and the E-Trac Forum for "2-Tone", "Two-Tone", or "TTF" (or some other variation) and you'll find a wealth of information.
