If you are in a low EMI, and low to moderate mineralization environment, you can run PAG=3, AC=70, DC=35 no sweat.

If EMI goes up, you can try bumping up a filter or two, or running single freq = 15Khz. If that doesn't help, you'll have to drop PAG=2, and try kickin' AC back up to recover the depth.

Hope this helps
