I recently got an ACE250 and have spent a little bit of time detecting. However, I'm still having a hard time deciding what to dig when I'm in a real trashy area. For example, I've found a school built in the late 50's in a bad part of town that doesn't appear to have been hunted at all. So, I get hits everywhere, but yet have to come to any fair conclusion as to what to dig and what not to dig. Any advice would be great. Do you guys generally only dig hits that are strong and solid? I've been staying away from hits that jump around to more than 2 ranges.
