So I have had my E-trac since June and the first few months of using it were definitely not dedicated to using TTF whatsoever. I felt for some reason that I would be fine picking out targets with multi tones. I had Goes4evers TTF setup in my E-trac since I got it, but it wasn't until the last couple months or so that I decided I needed to really try it and I'm thankful I have. My finds have definitely gone up lately because of using this mode. Most of the places I go have constant nulling on every swing and being able to put it in two tone and pick out the good targets amongst all of that is a blessing. I have gotten so accustomed to it that I don't really like the multi tones anymore. So thank you Terry for always pushing the TTF mode. It finally clicked for me
