Hey guys, I'm a new Etrac owner(<1month) and have had some decent success. Still getting used to the unit. I have a yard that I've taken some nicer old coins out of and have been going over it with the Etrac. I have been playing with TTF and am wondering....with all the ferrous noise you hear I occasionally get that high tone, but when I go back over the area...I will occasionally get it again amongst all the ferrous tones. My question is...should I be digging that occasional high tone or will the high tone usually repeat for a good target. In otherwords do you guys try to isolate that occasional high tone and still dig it with just a single chirp...or will the high tone usually repeat in TTF similar to when you are in the coins program running Multi/Conductive? I don't mind digging and looking, but it would be nice to know if those high tones usually repeat for you guys in TTF. I just don't have enough experience with it and have dug mostly nails. What am I missing?
