The best discrimination pattern is Iron Mask ON, All Metal. Listen to everything, dicriminate nothing...dig the good stuff. This allows you to run a smooth threshold, without all the nulling. And to pull the good stuff out of the crap. And as for the sensitivity, take it off of Semi-Auto and go to Manual and start at about 20 to 22. Oh, and ferrous tones...makes the iron stand out.

Here are your numbers:

This is the best advice! I switched to ferrous, AM.. and things are starting to come out of the woodwork. It's a hard, tough road to get use to all the tones, but pretty soon your brain will start to ignore the 'thuds'.. and you'll definitely perk up when you hear the 'good' stuff.

I really think going AM made all the difference for me. I'm finally starting to understand the issue with nulling, and can't believe I've been nulling good targets forever.

As usual Mike gives excellent info...indeed don't worry about discriminating as its going to cost you depth and perhaps a nice target masked out....Most of your excellent users do this and listen to all and excell.....if -16 is too noisy start out at -10 and slowly work into a setting of -16 and you also will excell....

Interesting. So there is a depth gain by going AM? Did not know that.

Thanks!!!

Yes...indeed. I learned this with the Quattro and it worked well with the Explorer II and now the SE. Once you get used to the idea, it falls into place. I also found that running max variability and max tone limits helps a lot. And I run gain at 6, maybe 7. Too much makes for an unstable machine. Same with the sensitivity...less is better than too much. And one other thing is run that threshold down. No need to have it any louder than necessary. And the traget volume as well. I have some nice Black Widow headphones. They shut out the outside noise very well. When you "open the machine up" as above, it can get a little "busy" with all those noises. No need to have it louder than you NEED it. Makes it more bearable if you "throttle back" the audio a bit.

I agree 100%. EXACTLY how I run mine.

That there is an air test, problem is, you don't get the same exact results in all the different types of soil and moisture conditions. The simplest method is to just detect with the machine and dig all repeatable solid sounding signals. Do this at each different site, you will find that some places in that specific soil that targets hit in different places than normal on your display. You will find that a particular trash item will display in the same spot over and over, same with good targets, but those results can be pretty specific to that site and differ slightly at another. The best discrimination is as little as possible. If you are digging coins, go into iron mask and just black out about the first eighth of the screen on the left side. This will eliminate most iron. Now, you sweep left and right over a target and turn 90 degrees and do it again, like x marks the spot. If in any of those sweeps, your machine nulls out (you stop hearing the constant hum of the threshold), if it nulls out in any of the sweep directions you just did, your looking at a rusted nail 99% of the time. It doesn't matter if the tones were high otherwise and they landed in the top right quarter of the display screen, which is where your best coins will show up on your display. Eventually, you can find coins under bottle tops and such by you noticing a slight change in the behavior of the tones your hearing or cursor movement, but that takes some experience and is impossible to explain. Detect, dig, remember, repeat. you'll get it.

THANKS FOR ALL THE HELP NOW I NEED TO GO FIND THE GOOD STUFF I WILL LET YOU KNOW HOW IT WORKS OUT I USED A QUATTRO FOR ABOUT 3 YEARS, SO HOPEFULLY IT ALL WORKS.
