The first few days you hunt with it you want to toss it. You ask yourself if you made a big mistake. Then you start to understand the numbers and the sounds. This is one machine that can be fine tuned for your way of hunting. And it goes deep! I have only had mine a couple weeks, and you can see that my silver finds are way over what I had been finding with the other detectors I have owned. I have a lot more to learn on this machine, but so far I am very impressed. I am lucky, as I have been watching every E-trac video on youtube for the last 3 years in anticipation of the day I would own one. They helped a lot.
