I did a field hunt on labor day, from a old map it showed a house once stood there ( a guy stopped while I was hunting and said a gas station once stood there) and has been on my list of places to try. The conditions could have been better ( field was corn stalks about 10" tall) but in these dry times we have been in I was happy with a place to hunt. Right away I new TTF would be the right choice from all the nulling I was getting in my coin mode, this is where I learned something about TTF, I would have to say 90% of the high tones I would get would also have a low tone (grunt) with it. I started really watching the screen and what I saw was the cursor jump from iron to other parts of the screen and almost every time it would do this in the coin range it was a coin. This made me think of seeing how the ctx 3030 target trace works, the etrac is doing the same thing it just does not show the trace. It was very slow going but it was worth it to me, and proof the etrac can find coins in heavy iron. So in about 3.5 hours I found 5 wheats (oldest 1910) the buff. and slq, 2 pendents one looks to be a dove and other missing the stone, and other trash items. Thanks 4 lookin Mike
