Ok so I have been using multi conduct more and more lately and it has been a godsend in the parks and private lawns. TTF has its place but I was getting tired in these places looking at my screen. I read a post not long ago giving tid numbers on gold. I came to the conlusion that other than digging nickel signals that I would dig all 12-09 signals due to the amount of gold that falls in this range. Although I have not dug any yet I'm pretty sure I'm due. My only trouble is that the sound of a 12-09 is the same in my deaf ears as a 12-02. So again I am forced at screen glancing again. The Etrac tones are actually quite simple if you do not overthink them.
