set it in ferrous sounds and two tones. Then there is a low tone for iron and a high tone for everything else. Set it fast

n deep

n; auto+3 or lower if needed.
Take some change and bullets or whatever you hunt and learn where the
conductive numbers hit, dig anything that hits those conductive numbers...
if the ferrous number is between 8 and 16.
That is a place to start, then as you learn it better, try more tones and different settings. Using ferrous sounds and two tones will eliminate most falsing. I hunt in a slightly enlarged relic pattern but the regular relic pattern will do just fine. I use it because I like to hear all the iron too. You may hear a little blip of high tone in the iron, if you can get it to repeat, even from one direction and the conductive number is correct... dig it, it is likely something all the other detectors miss.
Keep it simple at first with the two tones. Think of it as a more substantial F75. If the weight is bothering you, you probably have the shaft too long. Tweak the lenght often to be able to hunt longer with more comfort. Make it shorter when going uphill and longer when going downhill. The minute it begins to feel uncomfortable... adjust the length of the shaft, usually make it a little shorter.
Also... if you call it an E-TRAC it may work better for you... mine does not like being called an E-TRAK.
Most important... the conductive number does not lie, even if the target is really deep... unless the ferrous number is too high, then it's probably iron. Get out and dig until you learn. It took me a good year to begin to get comfortable with my Explorer SE, it took a few weeks with the T2, the Tejon was no problem and neither was the SovereignGT, however I don't think anyone ever stops learning about their detector.. especially one like the GT or the Tejon. The ET is probably the easiest detector I have ever had. Currently I use it and a V3. I use the V3 when I want to fool around with and learn a detector. I use the ET when I just want to make finds. I like finding coins and relics but I also enjoy learning to use a machine, that's why I am using both right now. When I got my SE I was doing very well with an F75. At that time I was hunting almost every day. I would spend an hour or two with the SE... not finding much, get frustrated and get out the F75 and immediately begin to make good finds in the same area I hunted with the Explorer. Now... there was nothing wrong with the Explorer, I just didn't understand it and I was hunting in conductive sounds and multi-tones. I fninally switched to Ferrous sounds and multi-tones and it began to make sense. However, I do not like ferrous/multi on the ET... I like ferrous/2tone.
Try making it a bit more simple and remember to tweak the shaft every twn minutes or so... all you have to do is lift the camlock and adjust the length.. it takes all of 5 seconds and makes a huge difference if it begins to bother you.
