The Neutrino Detector is such a pain to use that I simply don't. Not to mention it requires expensive volatiles.
Someone mentioned that perhaps the out-of-system pips (nearby stars, IIRC) should get filtered out after using it for a bit. Given the benefits vs the costs, I don't think that's enough.
I suggest, starting over each time you activate the Neutrino Detector, all mapped bodies get filtered out after a few seconds. Stars, planets, derelicts, everything. This would make it actually worth using, even if it required adding more downsides like having to stay still the whole time.
