Help !....With the A T Pro

Does anyone have any setting tips for the A T Pro ? I have had it for quite a while now and go out with it at least twice a week...but hardly ever find anything. I do not even remember when the last time I found any silver was. I am beginning to feel like I am just moral support for the people hunting near me....gotta be something that I am doing wrong.

I have the atpro and I found a lot of coins and good relics. I started in the preset coin mode and finally progressed to pro mode . what will help greatly is practice and listening to the different tones . I too did not find a lot of silver with the pro so I bought an etrac and am finding a lot of silver and other good relics but its been a lot of work .
