Gearlog's alcohol lab testing continues with Q3 Innovations' third model, the AlcoHAWK Micro. The Micro is the smallest in the AlcoHAWK series and fits right on your keychain.

PC Magazine's Erin Simon happily took the Micro for a night out on the town in NYC, hopping from bar to bar. The digital breathalyzer was lucky enough to see the likes of Nancy's Whiskey Pub, Union Pool, 17 Bar, and a couple of other bars in Brooklyn.

After chugging down two beers, Erin blew into the device for about 5 seconds and tested a .03. After three beers, she tested at .06. At the end of the night, the Micro displayed a .12 after she devoured 6 or so beers.

However, the Micro can test BAC levels up to .12 only, so her BAC level may have been higher than what the device told her. She felt that the device took a very long time to calibrate when you first turn it on. Plus, there's no timer on the device (like the one on the ABI and Slim I tested the week before), so it was difficult to know when to test your BAC level; you had to wait for the device to beep before it's ready to use.

On the other hand, she liked the size of the device, since it's hard to lose (unless of course, you lose your keys, then you're screwed), and she felt that it was a rather good icebreaker when it came to conversating.

When I spoke with Q3 Innovations, they informed me that the Micro is a good tool for a quick screening, especially for parents who want to test their kids when they come home from a party. But, if you're a regular Joe drinker, then you're better off with a device that can test BAC levels .2 and above.

The AlcoHAWK Micro runs on 3 AAA batteries and is available at Buy.com for $39.99.

Stay tuned for more digital breathalyzer testing this week.
