Trying to decide on buying the AT pro. I currently have the ACE 250. With the 250 I have to move fast across the target to get an accurate reading, if I move slow i get lots of different sounds on trash, good and bad. "metaldetectingoregon" has a video on youtube showing the Pro Mode reject a bottle cap then moves slow and gets good reads. Can you move slow over targets and get accurate readings with the AT Pro? Is he using the detector right by going slow over all his targets. This video really confuses me.
