Since Cam will be using those sensors, let me explain them from my experience with the old D6 West End Games Star Wars RPG. They had 4 modes of sensing, Passive, Active, Search and Focus.<br/><br/>Passive was short range and as it says, it's passive.  Think sonar.  You hear what is going on out there, and in this situation, what you hear is electronic signals, either power or active sensors.<br/><br/>Active was like modern rotating radar.  You sense all around you and can find asteroids and non-powered ships and the like in addition to sensing real live people out there at a longer range than just "running silent" on passive.<br/><br/>Search was where you got much higher range, but you focused your "radar" beam in one of the four quadrents only, like forward or aft.<br/><br/>Focus was close range, but was essentially like targeting them for blasters or torps.<br/><br/>Anyway, since Cam is telling me he damn well wants his active sensor package, how do we determine prices for such, and how much petty cash do we have?
