Tech 1 10% bonus to scan strength
Tech 2 15% bonus to scan strength
Tested on buzzard after realizing my astero had just 1 point less scan strength than my buzzard with the exact same rigs/modules.
Two Tech 1 rigs = 20% improved strength = 121 scan strength in my buzzard.
One Tech 2 rig = 15% improved strength = 123 scan strength in my buzzard.
Either the tech 2 or the tech 1 is not functioning as it needs to be functioning. I should have more scan strength with two tech 1 rigs at 20% versus 1 tech 2 rig at 15% increase, but I do not. I think the tech 2 rig is working as intended by the tech 1 isn’t
