Line of sight (clicks)?

[n.t.t.]

I played all SW games but never knew how much for example 400 clicks add to your line of sight.

1. So in terms of distance hom much squares on map 400 clicks add?

2. Dose it add to your basic line of sight or it is 400?

So I bought Qusasar (sensor 400 clicks) for MS (Astarte) but found it pretty redundant because I have only 3 slots with Tungsten (hull repair 20 HP/s), Kali (shild 3000, 10 SP/s) and Smog (active antimissile eff 40), even considering removing Smog for another Kali.

3. Whats yours system MS setting?

Puting sensor in MS is waste of system slot, I read someone puts them in fighter but I dont even do that. Didnt use one at all until I got MSF mission that required one at Muscovy.
