I took myself off this morning for a non-detecting visit to the 1,500 acre place, most of it under arable, where I’ve been doing most of my detecting recently to get some idea of what land might be detectable in the coming months. Since on my last visit it looked as though the field I was detecting was being ploughed imminently I wanted to agree with the landowner which other fields might be available between now and the end of the year.
As it happens, that field has not been ploughed any further because it was too dry, and is therefore still detectable for a short while pending the resumption of ploughing. I was, however, able to agree three new fields which have not yet been ploughed, totalling some 55 acres, in addition to the existing one. I was also pointed at a further field (30 acres) which I was told was detectable but which appears to have beans coming up.
Usefully, I now have a complete map of the farm with all fields named for future reference so there’s no confusion as to where I can and cannot detect.

Sounds good! I wish you luck and hope that your searches are fruitful.
Thanks John. This should be a decent area as there’s been some decent finds in the vicinity but nothing much on this farm. There again, apparently it has never been detected in any meaningful way. We shall see.
