Re: 11" DD Coil

I use an F4 with the same coil. I have found the center to be just above where the shaft is attached to the coil. I still have to cross over the target from multiple angles while pinpointing to narrow down the target area. With a little field time with the coil you should get a good feel for the center.

Re: 11" DD Coil

Hi Marcus, This is the J.W. Fisher forum and you'd get more answers to your question at the Fisher Research Lab section. JW Fisher makes Pulse detectors.

The best way to locate you coils sweet spot is to find clean ground and try it with a coin on the surface. I don't X the target with a DD coil but use the "Minelab Wiggle" as it works with all DD coils. Once you get a signal, slowly wiggle the coil back and forth while slowly pulling it toward you. When the signal disappears, stop then slowly push it forward till you again get the beep and the coin should be just off the tip of the coil. :coffee2:
