Ground Balance is a variable setting that increases detection depth in mineralized ground. This ground may contain salts, such as in wet beach sand or fine iron particles, such as in red earth. These minerals respond to a detector’s transmit field in a similar way that a target does. Due to the much larger mass of the ground compared to a buried target, the effect of mineralization can easily mask small targets. To correct this the Ground Balance setting removes the responding ground signals, so you clearly hear target signals and are not distracted by ground noise.
There are three main types of Ground Balance:
Manual Ground Balance – Manually adjust the Ground Balance setting, so the minimum amount of ground signal is heard.
Automatic Ground Balance – The detector automatically determines the best Ground Balance setting. This is quick, simple and more accurate than a manually set Ground Balance
Tracking Ground Balance – The detector continuously adjusts the Ground Balance setting while detecting. This ensures that the Ground Balance setting is always correct.
Minelab detectors use exclusive advanced technologies for superior ground balancing capabilities that cannot be matched by any other detectors.
