After about a year I finally will be able to get back out and detect again. I have an Eagle Spectrum and I know there is a difference between it and the XLT. Can someone tell me the best numbers where gold rings fall in at, or, what gold numbers are usually gold versus trash? I don't want to dig every signal but I don't mind digging most. What program should I use to get the coins and most jewelry, what numbers usually amount to trash, and what numbers are most productive? I know the detecter comes with a good ring and coin program, but there must be a good in-between. Accessable areas are getting scarce around here and I don't want to over dig if possible. Any suggestions would be appreciated.
