I took out my AT Pro out for its 1st hunt. Went to a couple different places and was unable to get anything but a '65 quarter. Discourged, I went home thinking I need more training on this machine. I sat down and watched some more videos and then It dawned on me what I was doing wrong. Having used a GTI 1500 for years, I always watch the target ID before digging and thats what I'm doing now....watching the TDI numbers. I realized that I should be listening to the audio report. This is more accurate in detecting targets in trashy areas. Well, we'll try again maybe tomorrow and see what happens.
