check your sensitivity make sure its up .. I did that one day and thought it was broke ,didn't cross my mind at the time .

...so turn my sensitivity all the way up?

Sensitivity all the way up, no luck. Here is a pic of my display with settings...

Digging440....how would i ground balance the AT PRO?

Glad you found the problem!

I have found that sometimes the coil tightening ring will loosen up over time, perhaps due to the small clearance you have to get your fingers around the nut and provide a "good twist".

Ground balance by holding the ground balance button while hovering the coil and moving up and down to the ground. This is covered in the most basic of the at pro learning videos that Garrett produced and are available online. Check 'em out! The AT pro is a great machine and the better you ground balance the better the depth.
Too bad that quarter isn't just a couple years older like the date on the cent to the right. GOOD LUCK OUT THAR!
