Ground balancing a metal detector can be a bit confusing and troublesome. We hope to clear some of it up here.
A metal detector that is properly ground balanced can allow it to perform much better and give a deeper and more accurate target id of what is in the ground.
Ground balancing is a process of canceling out the effects of ground mineralization and letting the detector only read the new targets and not the ground and the target. In a way it is a form of discrimination but in a good way. When you ground balance a detector what you are hoping to do is find the proper balance between the effects of the ground and not be positive or negative of a ground balance.
A positive ground balance setting can cause the minimization to produce a response just like a a good target if set to high. Especially if your sensitivity is set to high along with it. If this happens you can potentially miss good targets being masked by the detector seeing only the mineralization and not the good target.
A to negative ground balance setting can cause the detector to not see the ground minimization and or any new targets. Machine will run more quietly but you will experience a noticeable loss of depth on your detector. Neither of which is good.
A good balance between a negative setting and a positive setting is a must to active maximum depth and good target id for your metal detector. Generally fixed ground balance machines are slightly positive on the ground balance so it will works well in more conditions and soil types. Being a tiny bit positive on the detectors ground balance helps the machine run a bit smoother as well.
