An explaination...

So you have that big seismic buggy yeah. It weighs in at 60000 lbs. It has, as noted in correctly previously, 36 or 42 inch WIDE tires. The footprint of said tire having a ground pressure of no more than 16psi. My bike tire is pumped to 40, por ejemplo. Not that those two have anything related except that they both have wheels. That turn.
Meanwhile back at the ranch, the two engines burn diesel. One to move and one to vibrate the pad hanging in the middle. Put the pad down so the buggy is almost off the ground and rev that motor. if you look at the points on the map, linear ones are recievers and they stick in the gound surrounding he vibes and listen. sorta. Kinda. maybe. And this is how you get a 3D undergound geologic formation map. That you cant see or buy bc you dont have enough money. Thats about it.

As a tangent, I would like to play some ultimate like the good ol days back in the country village of Cairo.

This is what it looks like when someone messes up data points. Uh. Yep, thats about it.
