The Auto Detective Pen is Kojak and Colombo rolled into one. [Who? – Ed] Not only will it protect you against wireless sound bugs by flashing brightly once it detects a suspicious signal, but the secondary UV light lets you sniff out dodgy banknotes as well. Goodness knows the kind of company you’re keeping if you need all this hardware around (and does your Mommy know?) but no doubt you’ll have a good explanation down at the station. One off samples for $17.71.
