Minesweeper Question

[psimancer]

per most tv/movie shows shields are lowered unless combat looms (probably so the captain can spout those overly dramatic words " raise shields" thus informing the audience in its infinite intellegience that Violence will now commence (oh no hide the wimmin n chillin)

however justification is usually that the shields interfere with scientific sensors and are a major power drain

what i dont like is that we dont have a small (i'd say hardcode to max at 25%) settable chance to detect mines before we run over them i mean come on them scientific super sensors etc should be good for something right
