Accuracy You Can Trust
Advanced MicroCheck® Sensor Technology
The Keychain employs BACtrack's proprietary Advanced MicroCheck® Sensor Technology. Using a semiconductor as a base, these sensors go through a patented burn-in process, which delivers more accurate and reliable results, when compared to standard semiconductor sensors.
Optimal Breath Capture
Breathalyzer accuracy begins with an effective breath capture mechanism. The Keychain's innovative fold-out mouthpiece ensures only your breath goes into the breathalyzer, while ambient air, fumes, and other airborne gases are kept out.
The tiny BACtrack Keychain is perfect for BAC testing on the go, easily attaching to your keychain or fitting in a pocket or purse.

I use this almost every time I go out and it's fun (and educational) to see the results. I've always wanted one to help me gauge my limit and this is an extremely afforadable way to do it! I will likely be purchasing several of these for family and friends as stocking stuffers for Christmas!
