Mike Slocombe writing over at Digital Lifestyles cautions that the Informatica Wi-Fi Detector Pen is " only available in limited quantities for a limited time only". 'Touted as a 'business essential' by gadgety folks Informatica, the thing looks simple enough to operate: simply push on the button on the barrel and a green, yellow or red LED will light up to tell you the strength of any Wi-Fi signal in range, with the makers claiming that the pen can detect signals within an area of 50 feet. All this could be yours for just $18.95, with the pen also coming with a white LED flashlight so you can, err, point your light at any hotspots you find.
