Initial observations.
I found an uninhabited anarchy system about 150 LY from my bubble edge home base that has Alexadrite, Benitoite, Grandderite, LT Dia, VO, Moinssantite, and Serendibite in it.
I have now had both my ships scanned by three ships.
One of those was a "SYSTEM AUTHORITY". Both of the others were looking for stuff to steal and I had never logged off and back on or moved from Normal Space to SC and back. Now I suppose it is possible I got the 2 pirates because I had two ships drop into the same spot at different times although both of the pirates scanned both of my ships. Got a KWS on one but he was worthless.
Seismic Charges are not detonating on contact. They do follow the game designed 120 sec timer.
The quality of the graphics card does make a difference. Even with the same settings in game graphics, I can see more detail on my machine with the GTX 1050 TI OC than I can on the machine with the GTX 745 OEM. Both are on the same brand/model monitor also set for the same resolutions. But, even the 745 OEM seems good enough to do the prospecting and mining.
The rock I am shooting a prospector at must be glowing when I fire the limpet or the limpet will fail. So the PSW and the Prospector must be in the same fire group on different keys.
So far it appears that if there are visible surface deposits on a rock, there will not be anything inside the rock. Also the rocks with surface deposits seem to get a general all over glow from the PWS. The surface deposits are easy to see from some distance so at present I plan to ignore them since I have not found anything useful inside them. I really cannot see any difference between the effectiveness of the mining laser and the Abrasion blaster when trying to dislodge surface deposits. The abrasion blaster does better cleaning up the fragments dislodged by the SSM.
Rocks with sub-surface deposits seem to show a more mottled glow as you get closer to them with the brighter areas over the top of the subsurface deposits.
So far I have not found anything that is "core" and I have not yet managed to break any rocks apart with the SCL so I suspect that only rocks with core deposits can be broken up.
I have run out of Prospector Limpets so I have to head back and load up.
Also now thinking that I might want to put and Abrasion Blaster on the Refinery/Collector ship. Could make things go a bit faster when I have a friend sitting in the other chair running one of the ships. That way both could be cleaning fragments.
YMMV
Enjoy
