In my opinion, your having used the X-Terra will help diminish any "learning curve" that many find with the Etrac. I had a couple Explorers over the years and just never understood all the information the audio response provided. But after using the X-Terra for the past few years, I have to say that the Etrac sounds very similar. Although I've only been using the Etrac for a month or so, it hasn't posed many surprises. I have found that the "12 baseline" is a good starting point. But I find the ferrous numbers increase with target depth. Especially in mineralized or congested sites. I have dug dimes that will read a 17 / 46 in the ground and 12 / 46 when retrieved. I'm by no means an expert on the Etrac, but I attribute the variance of ferrous numbers to the mineralization. Around here, it seems the deeper the coin, the chance of providing a number larger than 12 increases proportionally. I run a modified coin program with only 5 or 6 changes. I dropped the Theshold to 17 for my hearing, increased the volume gain to 30, increased the variability to 28, reset the Recovery to fast on, set the trash density to high and set the Pinpoint to Sizing. Nothing fancy. Just what works for me. I am able to hunt much slower with the Etrac, compared to the X-Terra. Although the stock coil still creates a bit of a problem with this old crippled up body, the little 6 X 8 butterfly DD is awesome! Great separation, excellent depth and very sensitive to small targets.
Like I said, I've only been using it a month or so. And the type of hunting I enjoy is somewhat limited until the crops are harvested. I have only used this in a couple local parks and athletic fields but have found quite a few old coins. The first trip out I scored two silver quarters and two Merc dimes. I've found quite a few IH cents and more clad than I care to count. And I dug this nice 1874 last week in the local park.

I got the Etrac to "get me through" the summer months. And so far, I am not disappointed. The Etrac's ability to separate targets is second to none. JMHO HH Randy
