I watch youtube and listen. Everyone gets those clean angelic high tones with smooth "edges." It's beautiful. I can get those sounds on airtest, but never in the field (unless it's a surface find.)
Every e-trac signal I get is "thunky" and unrepeatable on all but the most pristine ground. TTF is even thunky.
At the last 5 houses I hunt, with TTF I get a "baw baw baw baw" as I sweep - every 6 inches sometimes. If I'm in coin mode and open the screen up, there are tons of iron signals reported, but I can never FIND the target (I am trying out of curiosity.)
I dig every high tone that repeats ..tons of empty holes at 12/44 and 18/45 type range - even with the screen opened up and two directions....but after a dig the X-1 sees nothing. After I dig, I open up the screen and suddenly the signal is iron. I never find the iron and give up. This is the same with two different coils.
Thinking of wrapping this E-trac around a tree.
The thunky sound is generally what happens on a deep target, and a gain setting can help or hurt. How high do you have it set? If your detector airtests fine bury those targets to try to eliminate a problem with the ground rejection circuitry. As long as you can detect a target you bury yourself there's no reason you can't find the ones that are already there.
The "baw baw baw baw" makes no sense to me. If you are running moderate settings an explorer, and I assume an E-trac, will run very smooth. If you haven't tried a factory reset I would great advise you do that. It is very common for these detectors to get glitches and even though they work to some degree, they can be a mess.... and people who are new just don't realize it. I have two friends who literally detected for months with a detector that needed to be reset. One was still finding stuff, but the tones were all screwed up, and the other guy lost so much confidence in the unit that even when I gave it back to him perfect, he soon sold it.
People dig the empty holes because they don't know the detector, don't trust it, and are using it like their old unit. On many detectors iron near a target gives a broken tone, and it's very difficult to know if it's iron that is sounding off, or a coin near iron, so many of us have just trained ourselves to dig all the high tones that are close. For the Minelabs a lot of iron nulls, and if your sens. isn't too high the detector should for the most part null over iron with the odd high tone, but for those tones there will be that certain something that tells you it's iron... and generally that's a null through the sound when you "X" it. Right now you could be running the sense too high and too many iron high tones are breaking through the disc., and because you don't know the detector, and hunting in the old style of digging any high tone that is close, you're chasing iron. I have never seen another detector with as good iron rejection as the Minelabs that still let you find the good stuff, and your experience is definitely not a reflection of how it really is, or could be. God I think back to using my GTI and I dig so much less iron with my Explorer I probably wouldn't post the numbers even if I knew them because many people would probably not think it would be possible that two higher end detectors could be so different.
Lastly if you're still using other detectors you are sabotaging your effort. Not only do detectors process the info. different but your brain has to do the same, and going back and forth just doesn't work. People that own an E-trac and several other detectors and use them all, well they don't know the Minelab, just think they do. There's no way you can REALLY know a detector inside and out if you're always switching, especially when the detectors are so different. So I think as much as you might have issues in experience and perhaps technical, the commitment to want to learn could also be part of it if your are getting frustrated and still grabbing your other unit. I don't say this because I'm guessing, I say it for having been through it as I dragged my damn GTI with me for probably almost a year for when my Minelab started to give me a headache, or we found a good site and I needed to be swinging something I knew. Only when I dropped the Garrett for good, hunted with another Explorer user who kicked my a$$ did I start to learn some of the mistakes I was making. You have a great detector, just need some great hands to make it work, but first make sure it is working and do some tests as well as that factory reset.
