The MineLab GPX 5000 has a coil selection setting for either mono or DD mode. The manual says either coil will run in the other mode. I was wondering if a DD coil running in mono mode would be as effective as the same size moo coil running in mono mode. Any idea?

Here is what John Porter told me. "I would not recommend using a DD coil in the Mono Coil/Rx mode with the Iron Reject option, it might seem like it works but there is a very REAL chance you'll leave good targets in the ground. Best bet is to revert back to the DD Coil/Rx mode and then check the target with the Iron Reject option (Try setting up a custom Search mode with Iron Reject already pre-selected to facilitate going from one Coil/Rx method to another)."
Double D coils can be run as Mono, but if you want to check how much stronger that signal is in mono flip the Coil/ RX button to Mono. The left side of the coil will be hot and see the target. Mono always runs deeper.

No. You'll always get better depth/sensitivity running a Mono coil.
