Detect that lets you see your target?

[awesomenessofme1]

I'm starting a supers game, and one of my players wants the ability to see supers, even if they're invisible or in darkness. He already has Detect (Powers) with Precise, so a successful Sense roll will allow him to know exactly what hex his target is in. Would there be a reasonable price for an enhancement along those lines on Detect? Alternatively, what would be reasonable limitation values for thinks like See Invisible, Dark Vision, etc. only applying to targets of his Detect?
