Ok this is not a post on which machine is better but I was out detecting the other day with a buddy of mine when I got a nice 12-42, 12-43 signal @ 8" down. I asked him to come over and check it for me as we usually compare targets. When he came over, he barely got it in the limited disc pattern he was using, but when he switched to clear screen he was getting an "iffy" 1-40,1-41 signal. Well I knew this was going to be silver since the wheaties come in at 12-36 up to 12-41 so after I was down 8", out pops a 1917 Merc in awesome shape. Could the CTX go deeper than the Etrac....I say yes
