Hi,
So far, so good. The only real observation I can make so far is that some steel bottlecaps will tend to gieve a mid-range "good" reading and then periodically "chirp" to a high 45. I have to work with this more, but be on the lookout for "good" items that bounce to 45. I believe it will prove to indicate the item is steel.
See the post at http://members5.boardhost.com/MetalDetecting/msg/1138259969.html
Most of us would advise hunting in the "all-metal" mode as many iron items can give a good reading now and then. If you notch out the negative numbers, all you hear are the false high readings and so you think you have an "iffy" good target. But with iron set to accept you find out the item is reading iron most of the time and only giving a false higher reading now and then.
If Monte reads this I hope he will post a copy of his "Quick Out" and "Edge Pass Rejection" methods here
We need a small coil. 6" has been mentioned which will be ok but frankly I was hoping for something even smaller, like a 5".
