I got a GTA 350 last month an I started thinking it wasn't working right.
I would get what I thought was a good signal but when I would dig there would be nothing there. This was happening all over my yard. Got to the point were I gave up trying to use it.
Today using an AT Max with a 4.5" Sniper and an AT Pro-Pointer, I'm thinking it's my yard.
First I had a little trouble finding a spot in my yard to ground balance my Max, seem like it would beep everywhere.
Using a Pinpointer I would try and search my hole but it would beep on the side of the hole like I just missed it with my hole.
I tried holding my Pinpointer to the side of the hole when I turned it on, seen that in this video

But it would still beep on the sides of the hole.
So I got a telescopic magnet and stuck that down in my hole and these little rocks stuck to it
Googled Iron Ore and I think that's what my yard is full of.
So my first finds were a pull tab, some kind of handle (seen in the picture on the left) that gives a nice 80 signal in and out of the hole, and a couple rocks
