Even if there is a hiking path nearby making higher chances for pull tabs, I'd still dig it. The iron is the biggest challenge and you may need to go over spots a few times. As Dan, stated, look for the other areas with activity whether it be thru listening to any iron pockets or if you see spots where other structures used to be. I have seen cellars that had as many as 5 wells (two at the main prop and three along the road within 300 ft). Just be aware of any open wells. Often barns can be across the old roads and are often overlooked by others. Realize too that any fields associated with the place were areas that were often worked and until the later part of the 19th century, they had no pockets in clothing. That, and they were plowed like farms today (but manually instead of with tractors). Some objects could have been turned deeper so bigger coils might be beneficial for these fields.
