ground mineralization

[ezra]

On a lot of the different indexes, people are constantly referring to how bad their ground is. My question is how do you determine how bad your ground is ? Is there a chart for individual states that determines how bad the ground is ? What factors or conditions are being used to make these conclusions? Thanks for the information.

I don't know of any thing quite like you're asking. Bad (mineralized) ground can show up in many areas. For instance, I live in an area where most of the ground is mild and you can run the sensitivity near full without ground chatter or other problems. A few miles away on the river beaches there is a lot of black sand that can make it difficult to get the best performance from a machine with preset ground balance and maybe even with auto or manual ground balance. White's MXT, in prospecting mode will give a number that indicates ground mineralization, but I don't know that it correlates to any thing other than higher or lower on its own display. In mountain areas the ground often changes over a few yards, as well.

If you're hunting over ground that forces you to turn down your sensitivity, and/or possibly add a bit of discrimination just to eliminate chatter and interference on your machine, you're definitely over bad ground. How severe would be indicated by how much adjustment is needed to be able to function. Unfortunately these conditions reduce depth, often considerably, and in the worst conditions some detectors can become nearly or basically, unusable. Hope this helps a bit.

BarberBill, I think I understand what your saying about how to determine your ground mineralization conditions. Thank-you for much for your response this makes sense to me as far as judging whats going on with the detectoras far the sensitivty in different araes Thanks again
