Whats the best setting for the Ace 250 with the Eq 10X14 coil. Went around my brother house last week and a old lady stop by and said yrs ago the owner back in the day 40-50 yrs ago buried there money in the yard. So I asked about where it might be at and she gave me a good size area to look for it and how deep. Which is about 1ft or more so now its time to find it, if its around. Later and HH
