Anyone know where I might find a VDI chart for the V3i?

To be a little more helpful:

Take a look at the VX3 Instruction Manual / Introduction / The Basics of VLF Operation / Phase & VDI

I made a chart last year showing VDI numbers. If you scroll to the left of the chart you will see VDI numbers for 40 different target types using 7 different possible frequency configurations. The chart shows how you can use single frequency to get even more resolution from VDI numbers. I will be updating the chart with oddball denominations (three cent pieces, half dimes, etc) soon.

You will need MS Office or Google Documents to view the sheet. Click Here for the link to the page:
