According to the core rulebook, scanner goggles "allow the user to see normally in dark conditions". This can be interpreted to mean that they remove all setback dice imposed by darkness. They cost 150 credits.
Then you have the Multi-optic sight weapon attachment, which removes two setback dice from darkness, smoke, fog and other sight-obscuring conditions. It costs 2,000 credits.
Finally there's the Enhanced optics suite attachment for armours. It does pretty much the same as the multi-optic sight above and cost 1,750 credits.
Is it just me, or does the scanner goggles appear to be the far superior option here? Granted they don't remove setback dice from smoke or fog, only darkness, but still they appear to completely neutralize any darkness modifiers. And at a fraction of the price. Any thought?
