Page 17: Ground Balance
Departement of international trade: https://aka-md.com | +74957991510 | akadetector@yandex.ru GROUND BALANCE Balancing the device to the ground is the single most important part of the device settings for accurate search results. Improper ground balanc- ing can result in decreased responses to targets and may result in insta- bility as well as an increase in false ground signals. -

For example, if you are air testing a large copper coin that would normally give a VDI of +82 to +84 but is now air testing with a VDI of -86. - Page 19 Departement of international trade: https://aka-md.com | +74957991510 | akadetector@yandex.ru 2.

This can be due to the uneven or lumpy nature of the soil.

Then smooth and slow, (start ing from a distance of 30-40 cm) present the soil to coil. (As if doing auto balance on the ground in the normal mode, but now you are mov- ing the soil to the coil instead of vice versa).

Advice on ground balance witch AKA devices in various conditions from an experienced searcher: If the soil vector on the screen loops (in the absence of metal of course), then this is a strong signal from the soil + dampness with a conductive medium (electrolyte).

Due to a sharp decrease in the influence of soil on the signal, the hodograph looping on large iron targets, such as pieces of roofing, agri- cultural implements, crumpled buckets, partially broken cast irons, etc., has much greater visibility, which provides an additional identification information for an experienced operator.
