I have a SE with a Pro coil on it.It is a pain in the adnoids to hunt with.The TID numbers jump all over the place.I found a 1923 Merc with it yesterday and to get a repeatable set of numbers that would indicate a coin was almost impossible.I have it setup with Bryce Browns settings out of Andy S.'s Explorer/Etrac book as a place to start.I'm hunting by the tones almost strictly.My problem is there are tons of stuff that give off the repeatble high shrill of silver.I'm swinging it slow and overlapping my swings.Is this just the nature of SE's.Any help or suggestions would be appreciated.Thanks Bill
