"Just like Buffalo Bill", you murmur as you pull on some light amplification goggles and take a look around.
You try to see a person 200m away (twice your goggles' range of 100m), so a Difficult task to begin with. It's dark (+2 diff mods), but the LA goggles take care of that. The person is sub-micro (+2 diff mods). Net effect (Difficult +2 diff mods), an Impossible task.
Meanwhile, your friend has no LA goggles, and also has a look. With unaided eyes, she has a base range of 1000m. She can quarter that to 250m, and offset 2 diff mods, while still keeping the base difficulty Average. Her difficulty for the task is Formidable (Average + 4 diff mods - 2 diff mods).
Put more generally, unaided eyes can offset 2 diff mods of darkness by quartering their range to 250m. That's a better base range than the 100m of LA goggles.
So ... what's the point of Light Amplification goggles? It seems you'd be better eating a few carrots and relying on your own eyes ... or am I missing something?
