The PG02B comes with a metric & inch ruler. Each ruler can be used for a right or left hand setup.
The update lets you switch from metric to inch or move to the left side for a left hand setup in seconds.
The PG02B comes with instructions in black & white but you can download a 2 page colored version that is a little easier to follow.
