High/low frequency what are they used for?

Depends on whether you want to talk to aliens near, or far... adjust your tin foil hat to suit.

For example of using both - The rock we work here, to get it to compact to good levels, For a single drum 12 Tonne Dynapack roller, we do 4 Passes on high vibes, and a minimum of 8 on low. That varies obviously but that gets our rock down and down well.
