Ака Berkut-5 VERSION 5.01 [39/43] About ground balancing

SCANNING TECHNIQUES

It is important to have good sweep or scanning techniques. Try to keep the coil

3-4 cm off of the ground moving the coil smoothly and evenly above the surface of the

ground. Try not to make any sharp or jerking movements of the coil.

The most important factor is the correct choice sweep speed. In most cases you

should do one complete movement of the coil (from right to left or from left to right) in 1-2

seconds. In strongly littered areas reducing the sweep speed of the coils is required in order to

achieve the best division between targets. Each following pass of the gauge should overlap

the previous, ideally half of diameter of the coil.

ABOUT GROUND BALANCING

Remember that ground balancing, while basic in its operation, is critical to proper

performance and to achieve the best depth and target ID.

It is important to check the correct ground balance level whenever search

conditions have changed. This would include the type of ground as well as temperature..

It is also important to ground balance on pure soil free of any metals. If this is

not possible you may excavate approximately 1.5 to 2 Kilo ( 3-4 lbs) of soil. Insure the

soil is clean of any metals and place in a plastic bag or plastic container.

Having laid the detector on the ground with the coil in the air go ahead and

activate the ground balance mode. Now present the sample of clean soil to the coil until

the ground balance melody has been heard.

If the melody fails to play try raising the CC or GN levels and repeat.

Once the ground balance procedure has been performed pay close attention to

the GB numbers and insure they do not differ greatly from 0. Should the exceed -15 to

+10 then it is likely that metal was present and the detector will be appear disabled.

In the course of searching the device makes automatic GB fine tuning (if AGB is

enabled). It is necessary to notice that in certain cases (For example, on strongly littered

ground) the device may erroneously track to the trash targets. In these situations it is

advised to disable the automatic ground tracking.
