Yesterday I went to a park and I couldn't get the AT Pro to settle down. The numbers were jumping from top to bottom even when it was sitting still. Ground balanced about 10 times, turned it of and on, tried going up and down on the manual GB, nothing seemed to work. The battery indicator was on 3/4 full but it would bounce around too. I tried disconnecting the coil plug and plugging it back in. I'm wondering if I need to change the batteries because it still has the ones it came with in it. But today in my yard it worked perfectly so I don't know what it's problem was. Are there areas that have so much crap in the ground that you can't run a metal detector over it?

more likely you were very near a high source of emf...cell tower,signal repeater,high power lines,cell phone in pocket...etc.also underground electrical lines can do the same.

I was close to a gas substation but there could have been a buried power line I suppose. I have an EMF meter (don't ask lol) I could go see just out of curiosity.

How low do y'all let the batteries get before y'all change them?

I always use rechargeables, so I always start the hunt with fully charged batteries.

Mine goes nuts when you're near emf. I know when my battery gets down halfway, I change them. At some point, at 1 bar of strength, mine will just start freaking out. The first time this happened, I thought it was toast until I changed the batteries

Mine has done this twice also, actually today was one of the days, changed freq's, turned it off and back on, nothing helped. But after a min it just stopped. My battery's are at half, I just figured it's either that or emf...or some ghost just wanted me gone.

Buried powerlines and/or high transmission overhead powerlines have done this to me before.
