Minelab E-Trac Field Reports

E Trac, a different animal

I bought the E Trac soon after it came out. I originally had some issues with it, but one trip to the NV location and it was repaired. I have been a White's man since around 1974 when the Coinmaster V Supreme came out. (Before AARP starts to E mail me, I was 13:lol::p.) I really bought the E Trac for two reasons. 1: I wanted a killer machine to see through the iron in very littered colonial cellar holes. And 2: To have a machine that would go deep in dry (non beach) sand conditions, mainly around those same cellar holes. My White's depth decreases by a couple of inches when the soil is bone dry. So that's why I bought it. I had some preconceived notions that I should not have had. It set me back many months. The E trac has not helped me much around the iron cellar holes. I can locate some small missed buttons and scrap, but so far have not found any coins I have missed with the DFX. Even when it hits on targets in the null. I have also not found it to go very deep in bone dry conditions. It does have a respectable depth, but not overly deep. Where it has excelled for me is in a non iron littered park, where it really does pick through the signals and does lock on to silver very nicely! It also has great depth in fields, and is unusually good in trap rock and torn up side walk areas. Mineralisation does not seem to affect it much, nor does EMI. Now remember no-one is an expert on this new machine, so what I have found is from my limited knowledge and experience with it. Now as far as the depth in moisture goes. I had it at a colonial cellar hole (posted the other day) and it hit on a Large Cent (what's left of it) at a solid 12" on the old road. It was a very solid tone and read 12-46 repeatedly. This was very impressive. I almost gave up on it, but at the last second it was out of the hole. So those are my impressions with it. Overall it is a great machine that needs lots of time to figure out how to get the best out of it. But don't try too hard to make it do what you want it to do. Just use it and learn what it is telling you. At first I thought that 6" was the limit I would get out of it. But changing to manual sensitivity (around 26) has increased the depth a lot. And of course, there has to be something deep for it to find. HH
 
I did ask Angel about whether I should be using manual sensitivity and he called me just as I was digging a good sounding target which turned out to be a clad dime at 6", to tell me that I have bad soil here. Thank you, Captain Obvious :lol: But also thank you for suggesting that I run it in auto +3 mode, which really stabilized things.

Only doing my part.

Now I'm off to change my phone number. :D :p

I found my first silver coin

I have been very pleased with my e trac I have alot to learn but thats o.k At first Ihad a heck of a time pin pointing but now its like money when I do my part its where the pinpointer says it is, Ifound my 1948 mercury dime at 13 inches ,I have found a few wheaties lots of qaurters and dimes ,This is very exciting Im having lots of fun Its like christmas every time you go even if Idont find anything thier is always the anticipation,Your metel detecting freind scott
 
Angie, it really depends on the soil. I've seen people claim to dig dimes at 8" with the ACE 250. Helps that they're in the sand at the volleyball court! :lol: But you never know. He could be in an area with no mineralization at all. Still hard to believe though. ;)
 
Well I finally got my etrac ordered today and hope to have it while I am off this weekend! I am going up to Duluth on Saturday and Sunday and may try it out at a couple spots I have in mind up there. I will keep ya posted.
 
I am just a little confused here. I have been reading documentation and I can not for the life of me figure out how a non-ferrous target can produce a ferrous reading on the display? I understand the conductive reading, but the other makes no sense to me. Any chance someone can enlighten me?

Keep Swing'in

See if this helps Jack.

On the White's VDI scale, the VDI number you get is really a phase angle showing the phase difference between the applied field from the transmit coil and the target's field produced by the Eddy currents. Now, instead of showing you a phase angle in degrees, White's created a scale from -95 to+95. The intensity of the target's signal comes in as the volume of the beep. So, the whole target response is what you would call a vector, with the magnitude represented by the volume and the angle represented by the VDI number.

On the ML, the same type of information is given, but instead of a vector (magnitude and direction), it is represented by a coordinate system made up of conductivity in one axis and ferrous in the other. Just because there is a non-zero ferrous component, it doesn't mean the target is ferrous, it just means that the phase angle between the transmit field and the target's signal is tipping in the direction that a pure ferrous item would have.

Remember the MXT's prospecting mode? It gave you a readout with the probability of the item being ferrous,
 
Thank you Rudy! I do remember the MXT probability reading. The axis description helped clarify things. I guess I need to get my hands on one these things. I am in trouble.:lol:
 
That sums it up

For those less technically oriented, like me, here is how I understood the FE vs CO numbers, based on Andy Sabisch's book.

The FE and CO components don't represent a true metallurgical analysis being performed on each target. They are arbitrarily assigned coordinates on a graph developed by the Minelab engineers. They might just as easily be thought of as "X" and "Y" or "apples" and "oranges" (these examples are directly from the book). They are relative values to give consistency to targets as passed under the coil.

The two components don't blend with one another (i.e. a change in one should not affect the other). There was some of this 'blending' on the earlier (explorer) models, but with the e-trac they have largely eliminated this.

They expanded the CO portion of the graph on the e-trac, without varying the FE portion, so that it is easier to identify targets by their CO value. What is really nice about the e-trac which was not the case with the explorers is that the CO number really does not vary much at all by ground conditions, so that although the FE number might bounce a little for deeper targets, the CO number stays consistent. I have found this to be true in the field with the e-trac. as compared with the SE where both values would bounce with deep targets.

I was dissapointed when I read that statement in Andy's book. I always dreamed:lol: that the technology was actually doing an analysis on the target. I didn't realise that it was an algorithm being done and not an actual sampling of the target. I guess I thought they shrunk a laboratory analyser of some sorts.:roll: So with this in mind, it's easy to see that the machine can be fooled when it classifies each target, even if it's just a bit. I find that pull tab ends (beaver ends) read 12-12 or 12-13, just like nickels do. So I think in a lab setting there is lots of room between numbers, but when you get it out in the real world, those gaps blend together. This is not good news for park and school hunters, but for me, it makes no difference, since I hunt mostly in the woods and dig all good responses. But you should see how many different readings you can get on shotgun shells:lol::lol: Depending on how old they are, what orientation they are in the ground and how long (tall) the sidewalls are, make a BIG difference in numbers, From 12-12 to 12-35 is what I have found. I don't think anyone will ever be able to tell gold from other metals with this machine with any certainty. You can narrow the odds a bit, but you will miss some gold due to the composition, weight and physical size of different rings. But this machine has it's place, and the corroded (1/2 weight) large cent I dug at 12" a bit back, showed me the E Trac has some depth to it, especially if the ground is wet undeneath. Mine does not like a wet surface, but it loves a wet sub surface!!
 
I hit a spot today that I've pounded hard before with the MXT and pulled several silver coins from. I had to use Auto +2 instead of Manual 26 because of the EMI. The Auto setting put me between 16 and 19 so the depth was cutoff too bad. I dug some clad I had missed due to iron and my first two nickels which came in at a solid 12-13. Sadly no silver. I don't think the silver around here sinks very deep. I'll keep trying to find some though....
 
Well, feeling pretty excited right now. I bought the Vision a little while ago, but always wondered what I was missing with the E-Trac. Well, I am about to find out.

Turns out my brother in law bought an E-Trac a month or so ago and has decided he really doesn't want it. Said he didn't have the time or desire to put in the time to learn and get good with it, so he has decided to stick with his old detector. Anyway, I kind of talked him into loaning the E-Trac to me for about a month so I could play with it and see what it can do.

So, any tips etc that can get me jump started on this thing will be greatly appreciated. I have already read the manual online, but know there is lots more to getting top performance out of it. Starting on Andy Sabisch's book tonight.

Thanks in advance!!

Dug a 1915 wheat today at 7" in some very hard and very dry ground. It came in loud and clear from 4 directions. FE bounced more than I was used to seeing it bounce, but the CO stayed within 42/44. The sound was nice though. I've hunted this 106 year old park now for 5 years and I've found 2 wheats and one silver dime. This IS a hunted out park. Not sure what those guys on the other forum mean by a hunted out park when they're pulling several silver coins and wheats. They need to try that in my park. :lol:
 
Hey Dale who's to say that the park has not already been hit by some guy with an E-trac already! You just never know I guess! :yes:

It's always possible, but unlikely. This park has been pounded for years and years. It's one of the oldest parks for miles in any direction. Plus the soil here is very dense. Coins seldom sink very deep. I was hoping to find coins that were covered by flood deposits, but this doesn't seem to be the case.

I did dig another wheat there today. But I think it will be my last for awhile. The ground is so dry and hard that it has cracked. We could use a little rain.

Have u tried All Metal with manual sens yet??thats how i find the deep targets.Dont have to worry about iron mask in all metal either.Try ferrous sounds,manual sens,all metal ..Good Luck!!! P.S Hope you can bring a shovel,you will need it for all the Deep targets! HeHe :)

You must be using an SE. The E-Trac and SE are not quite the same animals. I agree though that using all-metal where trash density isn't a problem can be advantageous.
 
SE or E-trac ,All metal will find more and deeper targets no matter which machine.With discrim u will null out good targets,its proven.Most of the guys i talk to using the E-trac or the explores use all metal.Who needs discrim when u have your ears to do that.With discrim on u cannot seperate targets sitting on top of or under iron if they are deep.In all metal the target speration is superb,u can hear each target u pass over,even if on top of each other.I have not had the pleasure of using the E-trac yet,but i dont think it will pick up items in discrim that the SE can only get in all metal.The detectors arent that diffrent ,I could be wrong .Plz feel free to explain the major diffrence in these machines if there is one,besides obvious upgrades.

I have used all-metal and disc throughout the years, and I have also used the SE, so you are preaching to the choir. :)

Actually, I have indeed picked up silver right along iron with the E-Trac while using a discrimination pattern. The E-Trac does have a much faster recovery after a null than the SE - it doesn't 'stick', so I don't have the concerns I would have had while using disc with the SE. I also prefer Conductive tones to Ferrous, which is why I use a slight discrimination pattern, otherwise my ears would bleed from the constant barrage of tones.

There is no arguing that all-metal offers advantages, and I do use it at certain sites, though not at the trashy parks I frequent.
 
Ive heard the E-trac has much faster recovery and is more sens.I personally would still use all metal ,as it deff gets deeper masked out targets i dont wanna miss.I use a headset with volume control so my ears dont fall off hehe.With the ferrous sounds its so easy to avoid the iron and hear the high tones i use it always.I have some vids on youtube digging some deeper targets ,some near iron you guys can check out.My youtube handle is NiagracountyNY.Im looking forward to getting the E-trac next spring.It would be great if i could use discrim and still get everything i can in all metal,but its not likely.Thx to all posting info on the E-trac,I enjoy it very much. Happy Hunting.. P.S Had to send my Se to nevada today,its sick.Cost me $110.00 via ups with insurance..OWCH!! Gonna use the Gti 2500 for a few weeks till its back...I miss her alrdy :)
