When I sold my 2000 Explorer,the guy that bought it did not want the X-1. I told him it was riveted on the upper shaft, he told me to keep it too, as he had an extra upper shaft. So, I didn't know if the upper shaft from an explorer would fit on my Etrac............ drum roll............It does! And I enjoy my Etrac even more. An idea if you've never tried it or needed a super small "sniper" coil. Remove your current coil off of your E, use electrical or duct tape and tape your X-1 onto the end of your lower shaft. I have extra lower shafts, so I just take current shaft off and attach a "blank" one on. This set up is super great when hunting an area that gives even 5 inch coils a fit. Great for sticking into crevices, as in looking for gold in a shallow stream, TTF in really, really bad ground, sure beats having to remove the trash to get your target. Hey G4E try it sometime in those super nail infested home sites..........nge
