if the old explorers are as good as everyone says, then wouldn't it be reasonable to suggest this E-Trac is a faster, and more advanced machine. technology is advancing everywhere and i'm sure minelab is no different. it would be self destructive for them to introduce a brand new machine using the same previous technology. just look at the trend...minelab will be out with something two years from now claiming it is better than the E-Trac, and you know what it probably will be because that is the nature of technology and a thriving company that obviously wants to supply a demand. Don't get me wrong, i agree 100 and 10 percent with constructive criticism, because that will actually assist in the process of bringing what people want to the field. I say give the E-trac a chance, it's still in its infancy after all. i say get one if in doubt and run it throught the gambit, criticise it, put it to the test, and then make an informed decision.....otherwise, don't get one, keep using whatever works for you and stick with it........
