I made the post quoted below in open forum recently and was asked to post it in this E Trac programme section to help throw some light on things for newcomers who might be having problems understanding things.
"Major problem for new E Trac owners is the manual is trying to cope with all sorts of levels of Knowledge and dare I say Intelligence. A good starting point is the Minelab factory preset mode and I would recommend any new owner to stay in that until they work out what all the settings do.
I have just looked at all the factory presets in the table at the back of the handbook and I would be perfectly happy to stay and detect and feel confident that I wouldnt miss much in any of those modes and would recommend any newcomers to do the same.
Everybody's going on about the threshold level being too high at 30. That is the factory preset level and its right in the middle of the scale 1 - 50. It is not too high for normal detecting if not using headphones, when using headphones it can be lowered to say around 15-20 where its just audible. Its there for a reason. If you couldnt hear that hum in the background how are you going to know when your sensitivity is too high. Also when your hum disappears momentarily it means you have just gone over a target thats being rejected. Its telling you all sorts that you need to know
When your sensitivity is set too high your threshold hum starts breaking up and you might even lose it totally. When this happens lower your manual sensitivity until the threshold hum comes back.
THE NEXT STEP TO MAKING YOUR OWN PATTERN UP.
My advice for a newcomer to the E Trac and the next obvious and sensible step after the Factory preset modes is to forget all about preset programmes from other sources even though it might seem a good idea to copy everybody elses because they might have been succesful once with it and found some hammered or staters. Go straight to the Quick mask screen and make your own to suit your style of detecting.
Press the quick mask button on the screen and you will be presented with a clear screen.
Next step decide what level of Ferrous and Conduct screening you want.
Using the navigation arrows on the bottom left start by pressing the right facing arrow three times. This will give you a conduct discrim reading of 3 on the left hand side. You can enter more or less than this but remember small hammered coins start showing from this point onwards. Under 3 will be mostly silver foil.
Next press the up arrow which will start raising the Ferrous black line. I have mine set on 33 which is two presses up from the bottom, the higher you go the more Iron and then good targets you will shut out so be careful. The lower you go the more Iron you will dig so a happy medium needs to be found.
Once you have the screen you want to use press the detect button and the screen will ask you if you want to load this quickmask screen into smart find, say ok.
Now this can be the base screen that you always use and can be also saved away as one of your modes. If you end your detecting session and turn off that screen it will be there again when you restart the next time.
As an addition to the above screen I have incorporated a small nails reject pattern into the corner of my quick mask screen that I made above. This is how I did it.
Once I had made the quick mask screen and pressed the detect button and answered yes to wether I wanted to use it as my Smartfind screen I then went back into the menu under discrimination and scrolled down to SAVE where I placed it into one of the my pattern modes by clicking on the right or left arrow to make it save, I then clicked detect to go back to the main screen.
Deciding I was happy with it I then went back to the discrimination Menu and scrolled down to Edit, this brought up the screen below
From the picture you can see that the top two boxes either side are hilighted black, these are the two modes to use, the one on the left is the small cursor the box on the right is the manual mode which lets you scroll around the screen.
The next stage is to manoever the small cursor down to the bottom right hand corner to begin making your nails pattern. This is where a little bit of practise and playing around comes in. With the cursor in the position where you want to start colouring in your screen press in the accept / reject button and you will notice that one click makes a small black square the next click removes it. By holding this button in while you move the appropriate navigation arrow you can proceed to quickly fill part of a line in with black squares.
By looking at my photo below you can work out roughly how high and how wide this nails reject pattern needs to be or as near as anyway.
Gordon Heritage actually made this nails pattern for me the first day I got my E Trac at the Wantage on Mud rally, thanks mate.
Once you have the screen looking similar to the one in the photo above click Detect button and you will be asked do you want to use it in the smartfind screen, click yes and detect.
You can then return to the Discrim menu and scroll down to save where you can then enter it into another my pattern screen and save it away as before by clicking the right or left navigation arrow. Once saved you can return and detect by simply pressing detect.
When you turn off the E Trac in this mode you will always return to it when you turn on again.
If you lose it you can always find it again in my patterns.
Another little tip, before saving these screens in my patterns make sure that all your other settings are as you want to save them away with that particular pattern.
The finished screen
The next stage for an owner progressing from factory presets is to run through the menu and decide what you want to change things to.
You have your quick mask detecting screen as a base so you want to change each setting in turn.
Sensitivity mode Auto or manual, they are both good. sometimes when the E Trac is unstable I will switch to Auto. you can choose the level of auto you want by pressing the navigation button up or down, It will change the values from +3 to -3, I usually leave mine on +3. Manual sensitivity is the normal way to go probably. this needs setting so that you keep things stable, the threshold hum helps to determine this. I usually try and set mine between 25 and 30 max.
Audio.
The settings below are aimed at giving Variable tone settings so that signals from left to right on the screen start low and rise progressively to a higher pitch. To understand what things sound like lay out a series of coins of different values and types plus some pieces of iron & other bits and bobs.
Threshold Level. Just audible around 15-20
Volume limit........30
Volume Gain.......24
Response..... Entirely to suit your preference for how you want to hear the signal. I mostly use Pitch hold, the easiest to listen to is Normal. the hardest is Smooth.
Number of tones.... Multi normally to give the fullest range of tones. Use the others if you prefer.
Tone ID...... Conduct (best for coin hunting) or Ferrous to suit the user.
Tone Variability.......30 max
Tone Limits............30 max
Threshold PITCH..... 1 very important for maximum variability.
Those are the main settings above.
Going in to the Expert part of the menu is really down to where your detecting and how trashy the ground is.
If in clean ground conditions I would probably set Deep on, Fast off. Trash density low, ground neutral or difficult.
If in some chattery ground I might set Deep off, fast on, Trash density high, ground difficult.
The preference menu is purely personal also.
Pinpoint mode can be chosen to suit yourself.
Hope this all helps a bit.
The setup above is what I use for a nice steady Variable tones programme. Other people have slightly different ways to go.
When you come down to it there are lots of settings on the E Trac and Explorers but very few that actually alter the performance drastically. Basically most of the settings especially in the Audio & tone menus are purely personal.
Try other peoples patterns & programmes on the E Trac Exchange but remember that they probably wont suit the conditions where you detect yourself. Setting up your own using the Quick mask screen and then adding the values that work for you has to be the way to go".
