BAC Track Mobile is a $150 personal breathalyzer. It uses the same sort of fuel cell technology as a professional police breathalyzer and can tell you if you are too impaired to drive.
We highly suggest you NEVER drive after drinking – even one drink. Remember, you can be arrested for impaired driving even if you’re under the legal limit of .08! That said, the device is interesting and educational. Results are displayed through a Bluetooth connection to your iPhone (4s or higher) or iPad (third generation or higher).
You can see your blood alcohol content, get an estimate as to when you will return to 0, and even post your results online! See ” http://www.bactrack.com/pages/bactrack-worldview” for a live map.
