I got my new e-trac after using the se for a year i thought i hunted this one place out i had gone over it with the se a bunch of times and today for the first time using the e-trac went over one of the same places i did with the se and only had 45 min till dark and found a standing liberty quarter i cant believe my se would not pick this up it was only about 5 inches deep i can say just from a hour of using the e-trac that it is the best detector i have ever used i am so glad i sold my se and got the e-trac i love it
