Mark One Eyeball
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Mark One Eyeball is a Colonial military term for visual reconnissance or flight plans improvised by the pilots themselves when searching for wreckage, survivors or managing other mission objectives. This becomes necessary when the use of technology isn't applicable or available due to unforeseen, unpredictable, or hazardous changes in completing a mission or task.
The CAP guarding the Majahual during a critical mining operation must use their Mark One Eyeballs when DRADIS cannot distinguish between the rock and debris in the asteroid system and enemy fighters harassing the mining operation (Scar).
