I asked this previously but did not get a clear answer.

In the Sensors line are two tiers, both give you Flee wide targeting sensor modules. The 2nd tier gives the same type of module but the only difference is the amount of 'threat' it shows on the module during assembly of the ship/boat.

Do the two modules (tier 1 and tier 2) stack? Meaning will you get more accuracy and more jamming by having all four on one ship/fleet, or no they do not stack only use the latest module?

Weapons and armor from each tier stack so my assumption is that they do. Also at what point is it where I don't need to stack accuracy? If I get it from two modules and from my weapon line (say missile augmentation) will I be wasting space better served elsewhere?

Also I was planning on adding to the Wiki so this information would go there once I get a definitive answer.

Happy Tuesday!
