The higher the module the faster and further away you can be for it to do its job.

I didn't know you had to "fire" it.... I've always had it equipped to a fire group, but when I select a target, after a couple of seconds it tells me if its wanted or clean. if its wanted, then I already have it selected and just fire away.
awesome, thanks! +rep for you.That is just the standard scanner you're using which tells you whether someone is wanted in the current system. The KWS has to be fired and tells you if the person is wanted in any other systems. In anarchy systems everybody shows as clean as there is no law, so a KWS is needed if you want to make bounty hunting money in these areas.
A KWS is also useful to increase the money you get on bounties - somebody who is wanted in your current system may also be wanted in another system. Using the KWS means that you can claim all bounties offered against the same person.
