You downed a few cold ones at happy hour and now it's time to head home. Are you okay to drive? You may not feel that buzzed, but in the eyes of the law you could be legally snockered. We'd hate to see you get pulled over and booked for DUI ("But officer, I did touch my nose on the third try!").

With the AlcoHawk, you can quickly check your own blood alcohol concentration before leaving the bar, cocktail party, or wherever. This FDA- and DOT/NHTSA-cleared digital alcohol screener measures to an accuracy of +/- 0.01%. You just blow into the folding mouthpiece and in seconds your %BAC is displayed. A little high, is it? Well, unless you like posing for police mug shots, you'd better hand your keys to a teetotaling pal or hail a cab!

The AlcoHawk is sleek and measures just 5"x1-3/4"x3/4", to fit easily in a coat pocket or glove compartment. Includes three reuseable mouthpieces and manual. Runs on two AA batteries, not included.
