It's currently available for pre-order for $199.
@rrhoover I think it's about time somebody invented this. Personally, I'm sick of having to carry around a whole bunch of different devices when I go a ghost huntin'. EMF Readers for spirits, ectoplasm goggles for poltergeists and... oh man, those proton packs. Ain't nobody got time for that.
