Getting easy Precursor Orbs:
Note: The following trick can only be done with the JETBoard. To get more orbs, go to Dead Town (where the Slums live).
Then get on your JETBoard (R2) and go northeast. You will
find a room full of water and some steps. In order to get to the
room and up the steps, do a trick on your JETBoard (X +
L1 + Left Analog-stick). You will find six Precursor
Orbs.
When you first use the JETBoard, try to get the "Gold"
high score. It will reward you with 9 Precursor Orbs. If you get
the "Silver" high score, it will reward you with 6 Precursor
Orbs. If you get the "Bronze" high score, it will reward
you with 3 Precursor Orbs.
Dead Town: Easy Precursor Orbs:
After getting the Jet Board, use it to skim across
the water to the northeast side of Dead Town. There should be
an opening under a ledge. Go through the opening and follow the
path inside it to find about ten orbs.
