Jim,
You will love the Nox for it's unmasking abilities. It's crazy fast in polluted sites and the 11" coil separates very well for such a large coil. I have the E-Trac as well so I know where you are coming from. The Nox is a very sensitive machine so there is no need to crank the sensitivity way up. I rarely hunt mine set over 20. Sometimes as low as 15 depending on the conditions. There seems to be a pervasive misconception that if you lower the sensitivity you will lose depth. The Nox is an excellent complimentary machine to the E-Trac. I wouldn't consider a site hunted properly/thoroughly until I had hunted it with both machines. Good luck.
