Spectrobes: Beyond the Portals Tips

Fastest way to Excavate
Trust me this is a good tip I have tons of evolved spectrobes and geos from this.

Go to any planet you want to go to and defeat all the krawl in the area.

scan for cubes/minerals/fossils.
once you find a cube/mineral/fossil start excavating it.
turn your scanner on and start excavating with fast taps on the fossil/cube/mineral and once you have at least 95% get out of scanning and search for the points you missed. If you cant find some dirt on the fossil/cube/mineral then go back to scan.

to excavate in lava or sand you can just blow into the mic if you don't have the tools.
