Quick buying guide

Which BACtrack should you choose?

“I go out most weekends”

You want app tracking so you can watch your BAC trend across the evening and know your estimated sober time before deciding how to get home.

→ Our pick: BACtrack Mobile Pro

“I just want peace of mind occasionally”

An affordable, simple device you keep in the car or by the door covers you for the handful of times a year you're unsure.

→ Our pick: BACtrack Scout

“I need the most accurate reading possible”

Go straight to professional fuel cell hardware — the class of sensor used in law-enforcement equipment, with consistent accuracy over thousands of tests.

→ Our pick: BACtrack S80 Pro

“I want it with me at all times”

If it's not with you, it can't help you. Keychain-format devices attach to what you already carry — your keys.
