Dark Reaper Range Finder
From Warhammer 40k - Lexicanum
The Dark Reaper Range Finder is a specialized Eldar targeting system used by Dark Reapers. Composed of a complex array of sensory and range-finding equipment incorporated into the helms of their Aspect Armour and tied directly into their weapon, Dark Reapers are able to target their enemies swiftly and accurately thanks to this equipment. While functionally similar to an Imperial Targeter, the Dark Reaper's version is much superior, allowing them, for example, to accurately hit a fast-moving target with ease.[1]
