Do you have a SunRay on the Etrac? I am trying to eliminate all variables. I would assume that you have already thought of any "variables" and already covered them. If you have done so and assuming you have a basic understanding of the Audio menu on the Etrac, then I must think there could be something wrong with your Etrac.
It sounds like there is a BIG difference in depth. I had three different Explorers in the past and two Etracs.
I am gonna go out on a limb here and say something that may upset people here and they will emphatically disagree with me.
Plain and simple,
The Explorers I had were just a little deeper than either of my Etracs.
I had the XS, EXII and SE Pro.
Yes the Etrac is more stable and may run a little smoother but from one machine to the other the Explorer is deeper. The XS I had and sold to my hunting buddy is a good bit deeper than my new Etrac. I am talking side by side on the same coin.
Just last weekend he was at 22 semi-auto. Now many of us know that means the XS will not go above said number. I had my Etrac on Auto+3 running at 26. The XS could sing on that measured 9-1/2" green, corroded Wheat just fine. I had PP'ed it an marked it with a golf tee because I am trying to teach him how to use his machine. No way my Etrac could hear it down at 22 manual.
Just in-case you are curious, I also set up his machine because he is as green at MD'ing as that Wheat was green.
I prefer the Etrac but the Explorers have more RAW power that the Etrac!
I don't know what more to say about your Etrac other than its possible that something is "out of tune".
Now I am wondering if I should click "Post Quick reply" because this may Stir the pot.

Thanks for the ideas everyone. Jeff, I tried your advice. The 10x12 sef coil on my Explorer 2 hits the dime easily at 8".
The same coil on the Etrac does not.
The Etrac w/pro coil does not hit the dime at 8", reburied dime at 7" and can get it to squeak.
