GROUND BALLANCE CONFUSION
- Thread starter LPB
- Start date
I may have become a bit lazy in my explanation of GB settings in relation to mineralization. BarnacleBill has an excellent post explaining it, in our FAQFAQ section. But briefly stated, "the ground phase reading ....has nothing to do with how mineralized the ground is. It is an indication of the type of ground, magnetic, conductive, or a combination of the two." Fortunately, the X-Terra is designed to "handle" both types! Regardless of the verbage, I'll still stick by my theory of 28 or less gets my DD. And 29 or higher gets a concentric.
Here is the link to another excellent post made by BarnacleBill, explaining how to measure the ground mineralization with the X-70.

My suggestion would be to put your detector in tracking, and check the ground phase reading every few steps. Let us know what those numbers are (as well as your sensitivity setting) and the actual ground mineralization readings you get using BarnacleBill's post from the link I attached. With all that information, we should get some good ideas as to what is causing the problems you have had with the 3 kHz.
Sorry if I've caused any confusion with my GB terminology. HH Randy

Hi Larry,
Generally speaking lower Michigan ground conditions are considered mild. Preset GB machines tend to work very well suffering little depth loss from iron mineralization. Having said that about preset machines things are a bit different when it comes to the newer detectors with adjustable or auto tracking GB systems. Target ID and ground filtering are done in software on the newer machines which IMO puts us in a new ballgame when it comes to how ground conditions affect performance. Whereas as older "analog" detectors with preset GB seem to care less about small changes in ground mineralization, the newer detectors need to be closer to spot on for best TID and depth performance (extreme low mineral and neutral ground excepted, see Bill's post on GB tones and low mineral ground]).
I'm just north of Traverse City and in my area the soil is for the most part sandy loam. Typical GB readings run in the teens and twenties in yards park and fields here with the amount and type of clay in the ground being the biggest factor in the changing numbers. Lake Michigan beaches in my immediate vicinty read in the low teens due to the low mineral quartz sand. Low teens you ask, isn't that high mineral ground? nope not high mineral, all the reading means is that the mineralization is iron (Fe) based, not the total amount.
DD or concentric coils? low mineral or high? Just use the one that works best for you in your conditions is the best advice I can give. Can the MF DD coil go deeper than a concentric in "low mineral" ground? The only way to find out is trying both in your ground., the results may be surprising.
While there are some general rules of thumb that can be applied to detectors and ground condtions, they don't apply everywhere even in so called mild ground.

Thanks all
I'm going to print out the info you wrote and try to figure it all out.
It's been cold here in Michigan and when nice days come, like today 4-23, I'm Busy.
When I answer I will start a new thread, as it might take a while.
But please know I am thankful for the time taken by both of you to help me out.
