Before creating an ID request please note you must:
1. include at least 2 photos of the item, both sides of a coin, or two angles of other items.
2. Include a ruler or other form of scale that clearly displays the scale in cm or inches. A coin or written dimensions is not acceptable.
Further information will also help, full guidance is below:
H - Have at least two good sized clear photos.
A - About your detecting day, type of land, depth found.
M - Measure items by doing the pics next to a scale or ruler.
M - Machine used and settings are interesting to other users.
Y - You will always get a better ID if you supply more information.
It was about 3 inches down in some woodland behind the site of an old hall that dated back to the 1840's.
I found it on Zero mode with My AT Max with discrimination set at 14,threshold at 1 and the sensitivity at 4.
