I'm a Canadian coin hunting in Canada using MXT E series in the coin-ring setting. I haven't been at this long but it appears that Canadian coins except the old silver coins and the newer pennies don't register like American coins. I found a American quarter two days back and it came through loud and clear. A Canadian quarter barley makes any sound and usually comes up as a pull tab. Anybody out there got any suggestions on settings to get Canadian coins? any help would be appreciated.
