If you're prone to participating in unscrupulous activities that might have law enforcement wanting to monitor your conversations, you can stay one step ahead with this ultra-thin bug detector that's easy to keep on your person at all times.
At less than a third of an inch thick it can be even slipped inside a wallet, assuming you're the George Costanza type who doesn't mind a little bulge in their back pocket. On a set of two coin-sized batteries the bug detector will sweep for RF signals across the 50-3,000 MHz range for up to 32 hours, reporting its findings either through a set of glowing LEDs, or an audible/vibrating alarm. At $300 paranoia doesn't come cheap, but it's a far cry from what your bail might be set at should the FBI find what they're looking for. [BrickHouse Security via The Red Ferret Journal]
