BACtrack Go keychain breathalyser – ultra‑portable pocket alcohol tester (white)
Small, sensible and surprisingly capable, the BACtrack Go is made for anyone who wants a quick way to check blood alcohol content (BAC) while out and about. Pop it on your keys or slip it in your pocket and you’ll barely notice it’s there until you need it. Using BACtrack’s Advanced MicroCheck sensor, it gives a fast BAC estimate in under 5 seconds—handy before driving, catching a train or making that late‑night call.
Key features
- The tiniest breathalyser designed for everyday carry; about 3.8 x 6.4 x 1.3 cm and roughly 57 g, so it won’t weigh down your keyring.
- Flip‑up folding mouthpiece keeps things hygienic and compact. Three replaceable mouthpieces are included, so friends and family can use it without fuss.
- Clear two‑digit blue LED display shows quick BAC results in seconds—no messing about with complicated menus.
- Runs on a single AAA battery (included) and delivers around 75 tests per battery in normal use.

- Comes with a full one‑year warranty, so you’ve got a bit of extra peace of mind if you’re relying on it regularly.
How to use
It’s dead simple to use. Wait 15 minutes after your last drink for a more accurate reading, flip up the mouthpiece, switch the unit on and blow steadily until the result appears. The LED shows your BAC in seconds. Mouthpieces are included so you can share it without passing germs around—practical and sensible.

This little device won’t replace professional law‑enforcement equipment if you need legal evidence, but for everyday use it solves a common problem: how to know whether it’s sensible to drive without faffing about. It’s quick to use, easy to carry and worth keeping handy—especially on nights out or when travelling. One final tip: alcohol affects people differently, so treat readings as a guide rather than an absolute guarantee. If in doubt, get a taxi or wait it out — that’s a proper bonus on chilly nights.
