I have just been playing around with some of the coins files available on the net. Thought it might be educational, if there was a trash file, to play around with different settings to see if one way was easier to recognize/separate different targets.
By varying the settings on the coins it has helped in the field. Just thought I might learn something from a common trash file.
I had the opportunity to search with two other Etracs recently. It was interesting how differently they read just because we were all were running different setting/patterns. That got me to playing with the emulator.
