I bought the Etrac because I guessed it was the newest version of the SE. I gambled and lost that bet! I was mad at myself for not having the cash at the time to get the discounted SE pros that were being offered. When the E trac hit I had to jump. I have been studying all the posts here and felt I was as familiar with the SE as one could be, without actually having one! I knew that it was going to be AM ferrous sounds, the little wiggle, etc. My DFX has been good to me, but it's only flaw was DEEP silver. I have a place where there is deep silver and time is short due to developers!! So that's why I jumped on the E Trac bus so fast. Even though I find great things with it, NONE of it has been past 5". And for me the 11" coil is useless. All of my good finds are with the small 4x7 coil in an open screen, ferrous, 2 tones, and sensitivity around 24. But I debated if I should get rid of the E Trac???? The answer is finally NO!!! It has not been what I wanted it to be, but it IS excellent in high trash areas. These quarters and dimes were in an area that you can't move your coil 2" without iron growl or just plain junk!! ET picked them out nicely. So it STAYS. Wish I had the bucks to get an SE also, but I don't. That's the way it's got to be. I will miss my window of opportunity for this site, but at least I will get some of the shallow finds. So I have added the ET to my arsenal. HH everyone and yes, I know I scratched the heck out of the 1894 Barber Pinpointing is real tough in that trash!!
