Those who are seriously into GPS (the worldwide global positioning system which uses a series of satellites to show their position within a few yards) will probably be rather frustrated with the simple interactivity of the Bushnell BackPack, but for the beginner looking to understand how it works and how to navigate with it, it can be a very useful gadget.
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.
