Can a 'spirit' or 'spirits' be detected with ?

Yes the greatest scientific results of all time is not being found with early 20th century equipment. Haha

No, since all these natural devices can detect only natural energies. Supernatural/spiritual realities are not detectable by natural means.

Yes with Paranormal Activity Radar

No, but Gin, Brandy, Whisky, Rum etc can and enjoyed in moderation; sadly I can no longer enjoy a well aged single malt whisky not even a dram due to health problems requiring medication. You only need to pop down to your local offlicence, pub or supermarket, no detectors needed just a glass to enjoy what Scot's call a ''half'' :-D

No, no, no, and no.  We simply don't have the technology to detect them.

Simple answer.......No 

I like to play vinyl Syd Barret pink floyd albums backwards. I don't know how anyone listened to Saucerful of Secrets and Piper at the Gates of Dawn forward. Play them backwards and spirits will talk to you. 

No, because spirits do not exist.

None of the above, but if you have a PA mixer, you'll notice that some inputs have "phantom power." Use this when spirits are present.

No.  There is no consistent and measurable evidence of spirits and no 'device' that can detect them.  Most of what you see (on TV, movies, and the Internet) regarding the supernatural is either faked for profit or the unsupported claims of believers.
