Hay Cassie,
The disappearing signal??????????????????
It's something that happens a lot and most people are not aware of.
When you disturb the dirt, it changes the way the metal detector
reacts to it.
A dug clod of dirt or sometimes a dug rock can mask a target completely.
That accounts for a lot of those ghost signals that people talk about when
they loose a signal and never find the target.
The target can be in the dug pile of dirt and not be detected. When you
put the dirt back in the hole. The fresh dug dirt can mask it again.
That makes people think that there was nothing ever there.
If you are not in manicured grass, kick or flatten the dug dirt and check again.
It may magically appear.
Happens all the time.
The same goes for a test garden. Freshly buried targets are usually harder
to detect than coins that are lost.
