Does upgrading sensors have any impact on the precision of these (I'm guessing no...)?
On a side note, I tried scouting the area on a SLF (left the mothership with NPC crew), but it is missing that SRV scanner, it's kinda hard to spot things if not on the lit side of the planet. Maybe they could add that, it already has a composition scanner after all
No, E-Grade Sensors over Planets will perform exactly like Grade 5 Engineered A-Grade Sensors. So no need for anything special on that, other than ensuring the Scanner Display is set to max. Range (10km).
If the POI is a classic RNG (not Geo or Bio) one, it's very well possible that it simply hasn't physically spawned.
Hence it can be exceedingly difficult to locate one directly and visually from a Mothership or SLF for that matter.
Some POIs used to spawn only at a minimum distance - while other POI types even only spawned for a deployed SRV.
So searching one exclusively with the Ship can be either tedious - or even impossible, unless it's a fixed (non-RNG) one like Geo, Bio or other fixed type.
(I haven't specifically tested for spawn behavior in a longer time but I think those mechanics did not change)
Notably, the only POI type that started off (unsure if that's still the case) as a large 10km circle but could shrink to pinpoint size.... were Outcrops in the center of huge Impact Craters.
Using that mechanic, those could be pinpointed from the Ship or SLF - although they were just a high-yield (more fragments) Outcrop and of very little use normally.
Only limitations remaining are the original ones :
- <1.5km Altitude AGL (Above Ground Level), the Scanner will no longer show any POIs as the indication starts fading below ~2km Altitude, so while searching for one the Ship must remain above that Altitude of ~2km for fullly unfaded bkue circles
- above approx. 25km (it can be a tad higher on some Planets), POIs will not be indicated on the Scanner at all, hence it's no good flying beyond that Altitude
- above approx. 35-50km (varies quite a bit depending on Planet size), the POIs won't even spawn and remain entirely undetectable
- any RNG-based POI can also spawn and be detected during Glide Phase, this affords covering terrain at 2500m/sec, regardless of Ship type
- time + RNG alone will typically spawn an RNG POI eventually, regardless of being in a Ship or SRV... the further away from Sol, the less likely they are to spawn per time spent traveling a Planet's surface by any means
