Hey Guys! Anyone have a problem on the Excal II with the threshhold slowly increasing during use? It has happened to me a couple times and I have finally powered it down and reset and it is fine. I checked for anything in the coil cover, etc. When it does this I continually reduce the threshhole until it finally turns the machine off. Strange. Other than that everything is great. Found over 20 gold rings, over 30 silver rings and close to a hundred costume rings. Hunting if fresh water. Any help will be appreciated. I plan on having a couple mods done during off season, headphones and coils. Thanks! Earl.
