Just in time for Halloween (actually, it has been around for a bit of time) the Japanese have scored one for the humans vs. ghosts. The GhostRadar with built-in flash drive is a great way to store your information and scan for ghosts where needed.
The idea is that the SolidAlliance gadget responds to unusual magnetic waves with audible alerts and flashing red lights. This can be used in various ways and it travels with you, so how convenient is that? Too bad it doesn't record the unusual magnetic waves to the jump drive for later so that you can invest time in investigating further.
