Khz settings on the Impact, Any recomendations?

[Ammoman]

Tomorrow i will be hitting a permission that dates back to the 1700s. The original owner was a slave trader so who knows what might come out of the ground? The ground conditions in the area will not be harsh but i expect any older coins to be pretty deep. So far the land has been hit by an Ace 250 with a few modern silvers and wheat's along with one Indian being pulled. I am mainly looking for coins but if a slave tag or shackle or two pop up i won't be disappointed. Any recommendations on which kHz i should use on my impact? i have the Impact pro package and will take both coils. I am thinking 5khz for deep silver, setting the gain as high as i can and 0 disc with the large coil. As far as modes go...maybe Di3?

I would hit it first at 14 kHz. Wouldn't want to miss out on any gold coins or gold rings. I'd also run DI3 , gain 95+, disc 03, Iron Vol. 01, no notch, Tones 15-35-70, Tone Breaks 15 & 65, iSat 01

Thank you Tom, I forgot about Gold coins. When it comes to gold coins, do you have any VDI numbers i might be on the look out for.
