is the fact that in All Metal my Eldorado can pick up a CW buckle at 11". I have a repro plate buried in my test garden and I was playing around today and tried my Eldorado in All Metal and it can pick it up a with a clear signal, but cannot if I have any discrimination enabled. The Vaquero and Cibola can't be effectively hunted in All-Metal because its only a push button option and not a toggle, like on the Eldorado. My MXT is able to pick up the plate as well, but doesn't give a VDI readout. So, in All Metal the Eldorado is pretty much the equal of the MXT, just a lot lighter.
