Does Scanning Sense still provide an active sense when "off"?
Pretty straightforward question that I surprisingly can't find a clear answer to—if you have Radar, can you detect other people's radar when your Radar is turned off? Does Sonar act as Ultrahearing when turned off? Or would you need to buy those abilities separately?

Bleh, the title was supposed to be "Does Scanning Sense still provide a passive sense when 'off'"?

Realistically, scanning senses are only designed to be sensitive to pretty narrow frequency ranges (at any one time) to avoid interference from other sources, but can certainly turn receiver and emitter on and off separately. As far as RAW goes it looks like you're supposed to turn everything on and off at once, but I'd certainly allow mixing things.

Ultrahearing most definitely has to be purchased separately. Knowing when someone else pings you using the particular frequency (sound, light, or otherwise) is a thornier question; as a GM I would probably let someone make a perception check for that.

I meant wavelength, not angle.

E.g. military SONAR specifically has the receivers on all the time AFAIK, even when they're sending out no pings, or <Sean Connery voice>'one ping only'</Sean Connery voice>.

Re: Does Scanning Sense still provide an active sense when "off"?
Well, the real thing is that a sonar detector is basically free on the scale of a submarine, so there's no real reason not to have both systems, but ultrahearing is not discounted for having sonar.
