Exactly, when the switch is pointed at Disc it's actually in pinpoint, and vice versa. I think the knob is just set up wrong (I did it). :|

Where I use it, there are cabins, vacation homes, and other residences along the riverside. I thought maybe I was picking up wifi signals.

In autotune, when the machine seems to be running well, I get a consistent low threshold until I sweep over mineralization or a target that causes the pitch of the threshold to change.

When it's not, each sweep of the coil in the current brings on a constant change in threshold, from low to high and back. I can swing my pinpointer under the coil to bring back the low threshold, but it only lasts for a second or so.

I "think" optimal performance in auto tune would consist of having a constant threshold, which should null out over iron, then return with a low threshold. And maybe if I swing over a deep "good" target, the threshold might disappear, but return with a high threshold.

So, what I have been doing is suffering through the cacophony of constantly changing threshold pitches, listening for that sudden, repeatable high or mid tone that signals either a coin or ring.

Thanks for the advice and assistance.

Yep, I know Beau--dug with him a couple of times on some organized hunts.

I really don't know what I need, except maintenance, and checking the knob settings.

Next question, Champ--what coils are available for the Excal?
