This illustration may help. When using conductive sounds there is no difference in the pitch of the sound at a reading of 31 no matter where it hits in the red conductive 31 zone. It is does not matter if it is at the far right or far left. Only a movement on the vertical axis produces a different pitch. When using ferrous sounds the change in pitch is based on a movement on the horizontal axis. No matter where a target hits in the 0 ferrous zone it has the same pitch. The target must move left for the pitch to decrease but up or down movemnt does not change the pitch.
I think where Bill and some others may be confused is that the actual movement is both on the vertical and horizontal axis. In the expanded screen these movements can be seen. It is a matter of up or down for ferrous conductive pitch changes and left or right for ferrous conductive changes. When it appears that an up or down movement has changed the pitch it is becasue there is also a left or right movement.
This may be a problem with the display screen in that these movements may not be seen so we think that there is just an up or down movement when in fact it is on both axis that the movement occurs.
