This was an interesting review to write – there are only a limited number of things you can do to review a breathalyzer and I don’t have access to sophisticated test equipment. So when it came to the operational review I had to resort to the “manual” approach with the aid of Mr Jack Daniels. Ahh, the things we do for science!
Before we get to that though, a quick overview. The BACTrack is designed to detect the presence (and amount) of alcohol flowing around your bloodstream. The value it gives is in the form of a Blood Alcohol Concentration (or BAC)%. It does this by measuring a sample of your breath.
Even a small BAC% can impair reaction times and judgement (try playing a video game after you’ve had a few beers if you don’t believe this) but the real danger is that you may feel OK to drive “the morning after the night before”, whilst still having a level of alcohol present in your system.
