Now I have no srv left all I can do is only scan the systems !
Actually, I'm in an ASP with only one SRV and I tend to do a low-pass fly-by on POI and don't even use my SRV. Center the blue circle right in front of you at around 2-2.5Km and once you hit the edge of the circle, drop to around 500m and slowly fly over. What was intended to spawn at the POI always shows up without having to get into the SRV. I have a feeling the POI circle radius is equidistant from what spawns there (which means the object is pretty much close to the center of the circle.. at least my experience so far). I'm slowly working my way to POLARIS checking out most planets on my way (at least superficially).
