“Upon receiving this keychain breathalyzer, I brought it to a friend's house to compare with their BacTrack S80 professional breathalyzer. Several repeated tests with both devices and multiple people confirmed that the keychain device was measuring at about half the BAC as the professional-grade device. In other words, this keychain breathalyzer would indicate 0.012 and the S80 would read 0.024. It seemed pretty consistent, at least, but the notion that it should need to be calibrated immediately upon buying it is ridiculous.”
“I am a Captain and purchased this item in the unlikely event of an accident on the water. I have piece of mind in knowing Bactrak is on board and will provide me evidence and piece of mind to show an alcohol free status”
