The E-Trac's discrimination is second to none, but you do have to throw it a bone (for people who like it quiet-ish), either by running a matchstick line of discrimination along the bottom of the screen in the quick mask (a la Des Dunne) or by editing the relic screen and making a custom fallen over backward L shaped pattern.

With this program if you get a two way signal you dig, hammies, small conductive etc will give you a low tone, large silver, Viccy pennies etc will give a high pitched smooth tone.  Large iron will also give a high tone but it will shriek and warble rather than be smooth.


Slow and Low is the way to go!!!!

Dig the high tones.....ignore the low tones......if you get a warbly mixed high & low tone at 90 degree angles....dig it.........high tone one way and a low tone at 90.....it's iron........

It will chirp a lot and testing indoors is almost impossible, outdoors is better but it sings when you go over a good find and after a while you get used to it, use headphones with a volume control knob as the good stuff has a good long tone and is crisper and cleaner. Lets discuss the discrimination pattern first. It's quite simple really.
Set your screen up in All Metal first. Then go into 'edit pattern' and black out on the very top line
FER 01 CO 01 to FER 01 CO 37. Leave FER 01 CO 38 to 48 open and black out FER 01 CO 49 & 50.
Why I hear you ask!
Here's the theory...well it's more than a theory because I'm personally convinced!!
On the ETrac, large deep iron will false and 'wrap' around the FE scale from FER35 to FER01. By masking out this line, it will quieten the machine down as on sites with loads of iron, this will confuse you and interrupt your routine as it will keep giving you 'blippy' high tones which you'll chase around.
By leaving out FER 01 CO 38 - 48, you'll still pick up large silver targets which sometimes appear in this area.
Again, many people will have opinions on this but this is mine!
So, that's the pattern.

This is really up to the user. Me?, I generally use Auto +3 and find it always ranges quite high where I go.
As of yet, nobody has given me any technical reason why Manual is better than Auto +3. They just say "It is". It has something to do with the way the 3 separate channels work I suspect.
I like Auto +3 because it always runs the ETrac properly letting me pick out signals without it popping and chirping. I think people miss many targets by running too hot.
Don't listen to the 'Max it out' brigade. You don't have to!!

Threshold Limit: 15 (This is good for my ears but is up to you)
Volume Limit:30 (Keep this at factory preset of 30)
Volume Gain:25 (The preset is 24. This basically enhances deep, faint signals so you can hear 'em better. I used to max this
out on 30 but I felt it was amplifying the ground too much and was getting a bit 'blippy')
Response:Normal (I like this the most as it give a generally nice and crisp target sound)
Tone ID: No. of tones - 2 (Will give a high and low tone)
Sounds - Ferrous (Will spilt the screen horizontally for tones) (FER 01 - 17 HIGH, FER 18 - 35 LOW)
Variability - 30 (doesn't effect us really!)
Limits - 30 (ditto)
Threshold pitch:15 (This is good for my ears)

Recovery Deep: On (This just enhances the deep, faint signals)
Recovery Fast: Off (Yanks use this in high trash ball park situations really. It helps to stop two close targets blending as
one target. Some argue with the faster CPU, you can have these both on together but people tend
not to. You deffo didn't have them both on with the SE.)
Trash Density: Low
Ground: Difficult (Okay, people will say that the jury is still out on this one. Tests were done with a large silver full crown
coin. For some reason, Neutral had some issues picking it up. Switching to Difficult made it blast through.
That was enough reason for me so it stays on Difficult.)

All other settings are personal preference.

So, switch on, Noise cancel and away you go. Dig ALL high tones and ignore the low tones.
Turn your headphones down a fraction and 'tune in'. I guarantee, after a short time, you'll get used to the low grunts and be picking out the smallest of high tones for further investigation.
