Ok, had my first outing with the E-trac. Mind you I have absolutely NO EXPERIENCE with this machine or any Minelab machines. I had plenty of signals, but had no idea what they were and what type of target I might have under my coil. I knew from watching videos that the sweet spot was in the 12 -40's etc, but I was getting alot of signals that I didn't know to dig or not. I know I should be digging everything at this point, but it was a dreary day and I wanted to make the most of my time. I got home and decided to do some homework to familiarize myself with the Fe - Co numbers. I realize that different conditions may make for different results. Either way, as a total novice, I hope this will be helpful to more than just me. I went through every type of keeper coin I could find in my collection and compiled this list. Feel free to offer up suggestions and perhaps we can have a master list for the people of this forum to use. Her goes...
