With Range Amplification 5 and CalScout 5, your passive scan radius is 45m. That is roughly the optimal range of a Plasma Rifle, or comfortably within optimal of the other rifles. With a single Complex Range Amp, you get a 65.25m radius and can still fit a Damp, bringing your profile down to 20.08db: enough to evade all but the lowest of scans.

What this means is that you can scan down enormous areas and be hard to detect, but you have to make a choice: you can fill some of your highs to become the third best Scout hunter but be vulnerable due to low EHP; you can dampen to avoid all scans, just like all other Scouts but it doesn't cut into your primary tank and you can still have a 45m scan radius; or you can do whatever - the change to the CalScout was needed to stop them being the best at almost everything (except dampening, which only the Gallente could do at the time) and now they still have the capacity to do what you want but it is not just handed to you on a silver platter.

Edit:
In other words, the CalScout is just fine, like all the others now that Charlie jiggered the bonuses.
