Thanks everyone for the fast responses! I guess I should have just tried digging a few trial targets to learn, after reading everybody else's success stories I wanted to cherry pick some real nice loot.
I know how to change from auto to manual, but no where in the sensitivity select screen do I see a place to change from +2 to +3, or to change my manual sensitivity setting, if that makes sense. I'm sure I'm missing something extremely simple. So here is what I do, step by step, please insert the additional step I need to take. People are saying to hold down the button for the menu to pop up, but all I have to do on mine is press it once?
I press the left arrow key while I'm detecting, the sensitivity screen pops up, but all I can do is either go up or down, to pick either auto or manual. I just bought it, but I imagine it was in the store since the 3030 came out. Perhaps I should update the software?
