Ya know,Ive had an ETrac for over 3 years now. Several times Ive started to ditch it, but decided to let it hang around because I liked it in the parks and school yards,anywhere I had to be selective about my digging. Smallest coil I had was the Sunray 8 inch (a good coil btw). I have a lot of spots that are very littered with iron, and some with iron and modern trash. But, I always used a different machine in those areas. A few of the guys on this forum and another forum talked me into the 4.5x7 excellerator coil;well,I bit. That coil changed the personality of my ETrac,it really did, something just clicked (though Ive never tried the other small coils,they may have done the same and Im sure they work well). But this coil, still has a good ground coverage (gotta remember there was a time an 8 inch coil was big) and really lets me work those tight signals. I dont lay my ETrac down now when I hit those spots. But. I feel pretty sure one of the other small coils will work out for you, Ive seen to many good post on them. I just didnt see anyone mention this coil, so I tossed it out there for you to ponder on,lol.
