Seismic is the technology that makes the machine and
soil work together.
Seismic is the innovation that lets the roller determine
the optimum frequency for any compacted material,
monitoring the variations and constantly adjusting to
the changing conditions automatically.
Adjustable (Variable) frequency - (Optional)

Optimum vibration speed depends on the soil type that
is to be compacted and the chosen vibration amplitude.
If double jumps occur, reduce the vibration frequency
if possible as an initial measure.
If this does not help, select a lower amplitude instead,
if possible.
