I'm Sensing Something

Its been stated before energy sensors would have greater range then what's stated in the book. I think the book reflect game scale and playability decisions. Perhaps we can adjust the range and set numbers for the chance to detect at 500,000 that are easier then detection at greater ranges. Basically at 500,000 detection is automatic and at 500,001 to 1,000,000 there is a skill role required. Difficulty modifiers for range would seem appropriate. Stealth technology could be a factor. Actions taken by the party that wants to hide could also be a factor.
