How drunk are you? No, really? How do you know?
If you’re a regular imbiber, it’s a good idea to test yourself once in awhile to make sure you’re OK to drive. 0.08 percent blood alcohol content (BAC) is the maximum legal level in most states, but knowing if you’re over that threshold can be difficult (particularly as you get closer and closer to it).
Portable blood alcohol testers can be helpful, but many require patience and luck to get them to work properly. Here’s a look at two very different models from AlcoHAWK, one of the leaders in personal breath analyzers.
AlcoHAWK Slim Ultra fits in a pocket and is about the size of a cell phone. The unit works well… when it works. Making that happen requires blowing into the unit for five seconds, turning it on, then waiting for it to count down from 100 to zero, a process that can take several minutes. Then, more often than not, the unit signals that it has an error. You have to repeat the entire process from scratch, then hope for the best. Sometimes you need one reboot, sometimes four. We never got it to work right on the first try, but when we did finally get it going, it offered results exactly in line with the more professional tester (accurate to three decimal places) that we had to compare with.

AlcoHAWK One Test is a single-use breath alcohol tester that has pretty limited value no matter what you’ve been up to that evening. It’s a slim tube the size of a cigarette that works only once. To use it, you puncture both ends, then blow into it like a straw. You then wait basically wait until the yellow crystals inside turn green. If the level of greenness crosses the line and red dot on the tube, you’re over 0.05% BAC — and presumably you shouldn’t drive. The accuracy is questionable, and I imagine if you are drunk enough to see a lot of green crystals in here, you know you shouldn’t be driving anywhere. But at least it’s portable.
