BOW2U,
This truly is magic technology. What we see in the snap shots is nothing compared to what our geoligists see when they can rotate the displays and peek under any rock they want to (pun intended). I've seen similar stuff used in the oilpatch and it fascinates me every time.
Quantec's (continuing) involvement in SLI is yet another piece of the DD that keeps me here for the long haul.
