“GROUND BALANCING” function.
SPECTRA analyses both the soil mineral content & level of wetness,
the result appears as GROUND VALUE identification number, on a scale 00 to 99.This identification number informs the user of the ground type to be scanned.
The DGB - digital ground balancing feature, was developed for SPECTRA for reliable target indication,to maintain maximum range and stable operation regardless of the ground type.Even further the "SPECTRA track" system, completes the ground balancing accurately, by selecting variable waveforms on the transmit frequency to match the soil.

It is a simple and expensive generator. No Ground balance


It has a inner timer so at first 2...3 minutes it display ground scaning, but it give the desired frequency at the probes. It only writes "Ground balance", nothing else


With some words... "Very expensive generator for its ability"
