Greetings. I would like to do the GS to search for gold nuggets, from what I have read in this forum it would be necessary to use a DD coil for the natural cancellation of the effect in highly mineralized soils. Any other suggestions?

No, a DD coil doesn't work any better for ground. Some Minelab models use a DD in a cancellation mode but that requires special circuitry which the GS does not have.

Ok, Carl. Thank You. The TDI is Best with DD for gold nuggets? or GoldScan With Mono Coil?

[Carl-NC]

They should both be about the same, and I would use a mono coil with both.

Can you give me the information about the title, Eduardo?
Mono coil, 13".
