Metal detectors auto ground balance
Metal detectors have become increasingly popular lately and many new or improved models have been introduced for this trendy hobby of relic hunting. Machines are becoming more and more technical, with all possible advanced technology implemented. Current high end models go beyond metal detecting, providing radar technology with a 3D display of the ground below, up to a 25 foot depth.
But regular people practicing relic hunting for fun do not want to go berserk with features and expensive machinery. Nevertheless, some implemented features are deemed necessary and useful and established themselves as standard features with quality producers of metal detecting apparatuses. One such trait which is generally viewed as vital to the relic hunting devotee is the ground balance.
What is ground balance and why do metal detectors, or rather relic hunters need it?
When relic hunters are on the hunt, they search with their metal detectors the soil below for buried and hidden metal artifacts. These relics are the ultimate goal of a treasure hunter, no matter if they are simple five cent pieces or Spanish silver dollars. Unfortunately, in the soil, there are not only such treasures, but other minerals and junk metal, predominantly iron. Mineralized soil very often did disturb metal detectors and delivered false positives, until someone figured out how to eliminate such false positives with ground balance.
Ground balancing a metal detector is a function whereby the user manually, by means of presets or with automatic ground balancing features is able to eliminate these minerals and iron, which deliver these false positives, or mask the true treasure hidden between them. Versions which feature preset ground balancing in combination with manual adjustments are also being offered.
Metal detectors with an auto balancing software controlling the metal detector and automatically adjusting the sensing mechanism are more expensive than the ones with preset features or with the manual adjustment capabilities. The sophisticated programming automatically adjusts to the soil beneath, thereby eliminating the unwanted minerals and metals like iron and allowing the metal detector to detect only the metals which are meant to be targeted. Unfortunately such automatized feature is not always the best solution, because if the apparatus is adjusting at the moment when you are passing over an object which you would actually like to find, the metal detector will not “see” it. On the other hand, if an artifact is lodged in mineralized soil, with a lot of iron, once the automatic adjustment is done, you can search the soil as if it were free of any disturbances.
