the auto-tune system got frozen and could not rebalance (extraordinary but possible
event), don't worry and turn off the device, turn it on holding "+" button, similar to the
coil replacement procedure (see "Searchcoil Replacement Procedure").
After you have learned how to choose the balancing area, memorize the
approximate balance digit in lower left corner of the screen in the balancing mode.
Its sharp difference, especially in same weather conditions, during next balancing may be
caused by metal in the ground, and you should change the ground balancing area for
your device.
If there were a metal object under the coil that had not allowed to make automatic
balancing (objects with VDI close to 0; foil, for instance), then the device would give two
consequent short tones, with a tonality similar to the iron signal in the search mode, and
an exclamation mark in a triangle would popup on the screen with the sound.
So, the balancing should be performed in another area. The digital value of the balance
level (phase) pops up in lower left corner of the screen when balancing is over, this is the
value the device will use to correct the VDI of the target, eliminating the ground
influence. Digits, showing ground mineralization level will be displayed in the right
corner, in accordance with the device scale.
It is worth to mention that every device has a unique average angle of the
ground balance phase and may also depend on the technical parameter spread of the
searchcoil and ambient temperature.
But, taking those values into account, don not forget that your device stays in
the automatic balancing mode and it can elect to rebalance by ... a shovel, boots, your
partner.
That is why, if you want to review device screen and balance
numbers after the automatic balancing, press the button one
more time , and enter the manual balancing mode to turn
off the automatic mode.

On irregular mineralization soils, for instance on a plow
land, the device cannot always be accurately balanced in the
automatic mode, because when a vertical balancing is performed, there is one soil under
