I just bought the giga digging tool and it won't work right!!!!!!!!!!!..

First you have to dig up the fossil for Giga to dig it up automaticcly.

If you use the giga tool on a mineral which you have PERFECTLY excavated before, it will excavate perfectly again. However, if you have not, the percentage that is above ground (excavated) will be the percentage of how much chance your giga tool has of getting it out. I, myself just exit the fossils, already got too much. I only go for the minerals....L.O.L. (laugh out loud)

Ok, look it took me a while to get the hang of this to, but here it is: on the top of the screen you see a line (not the one going back and forth) but the one right above that is the meter you need to watch if it hits red you lose, but to prevent that use your larg drill to break down most of the rocks around the thing you excavating and then use your small or medium drill to finish it off, don't leave your drill on the item because then you are damaging that item and can not be repaired unless you have the repair tool from HQ.

I don't have the tool yet but I asked the guy next to the guy with the mining shop and he says something along the lines of "once you find a mineral you can dig it up if it's the same, but don't try it on fossils" so another words he's saying use it on minerals not on fossils (cubes I think are with minerals)

Giga don't work on fossils
Needs sucessful ecavation for minerals
