Has anyone ever found a good target with an E-trac/CTX reading of 01-19 to 01-26? when I first got my E-trac years ago, I dug every signal in the "non-ferrous" zone. Of the hundreds of targets in that range, every single one of them were bottle caps, so, I now ignore them. If I'm running an open screen in TTF, those numbers come through loud and clear, which makes me wonder why Minelab chose to include them in the "good" target zone. Am I passing up some "unknown to me" treasure?
