I have read several books and watched numerous videos multiple times. Because of it's many options (like you said), I believe it is a little intimidating, especially for someone who hasn't had much field time with it. Is the ATX Garretts new gold machine? Do you have an ATX?
I also have a Fisher Gold Bug 2 which is much easier learning to use so far. I purchased the GPX to give me a tool for greater depth. Do you know what kind of depth the ATX is capable of?
Thanks for the input!
