If you've been using the X-Terra in the multiple tone mode, you should have a relatively easy transition to the Etrac. Everyone has their preferences for settings, based on the targets they are after and the sites they hunt. And the stock programs will work well for many. But in my moderate soil conditions, looking for old coins at old farmsites, a couple parks and some private yards, I run mine in a modified coin program with a few adjustments. I lower my threshold to a barely audible tone, raise the Volume Gain to 28, raised the Variability to 29, set fast ON, Trash density to high and Ground to difficult. I mostly hunt in auto sensitivity and sometimes bump it up or down a peg or two, depending on how close the targets are. I also modified my Quick Mask program by rejecting 4 horizontal bars on the ferrous and 3 vertical bars on the conductive. I find that the Quick Mask takes a lot of guess work out of those "iffy" targets. Like I said, everyone has their preferences. This is what I've found to work well for me....... so far! The best advice I can give you is to read and understand how each setting effects the operation of the Etrac. Once you understand what makes this thing tick, you'll be able to tweak yours to match your style of hunting and your sites. JMHO HH Randy
