The people who switch from the Explorer to the E-TRAC and don't like it are people who have become really good with the Explorer in AM mode. The AM ferrous on the E-TRAC doesn't have as high of a resolution, IMO, as the Explorer. So if you are used to hunting in AM. ferrous tones, you will have to change your ways with the E-TRAC. The E-TRAC need's a bit of disc in order to perform it's best seperation in iron and trash.
They straightened the conductive line in the E-TRAC so that it does not go from the bottom left toward the upper right, it goes straight up and down. This helps the conductive number stay steady but many of the ferrous numbers are bunched around 12. That said, once you learn it and know a little about the site you are on, then E-TRAC will produce for you because of the reliable conductive number, (no more crosshairs that jump from upper left to lower right). I never use the crossharis with the E-TRAC. The numeric display is all I need. Also, if you use the smartscreen, the numbers are displayed above it for reference.
I used the SE for over a year and it was a struggle for me the whole time. The last few months I began to grasp it by going to AM ferrous BUT. the E-TRAC was easy and productive from day one. I love it!!
I have hunted alongside an F75 and, that day, dug a carved bullet, (from a park that has been hunted hard since the 60s), that the F75 said was trash. It was at about 7" in bad ground. Yesterday I stopped at Springlake park in Atlanta. It is a small pocket park right at the corner of Howell Mill Rd and Collier Rd and a "hot spot" on the Confederate side of the battle of Peachtree Creek, of course it was "hunted out" years ago. I dug a fired minnie, (one of those mushroomed bullets), a 1943 war nickel, a 1953 silver dime, and an artillary frag.
The E-TRAC with the new "Pro Coil" is really a great machine but it is NOT an Explorer, it is different. If you realize that and don't try to make it be an Explorer, you will like it.
It is my favorite machine. I also have a Tejon with a 575 coil that I sometimes use but it has nothing on the ET. A SovereignGT that I think is better on jewelery and especially rings. A T2 that I just bought a small 4.75 coil for and it is a good machine, but again, has nothing on the ET. I keep the ET and the T2 in my truck all the time.
