ClearSense Pro Breathalyzer
Couldn't load pickup availability
Reads blood alcohol content using the same fuel cell sensor class found in professional police units. A live digital display shows your exact BAC number, not a vague yes or no.
Small enough to live in a glove box, purse, or jacket pocket. Results appear in about 5 seconds, and the sensor tracks within ±0.005 of professional roadside devices. A quick yearly recalibration keeps it at peak accuracy.
1. Press the start button.
2. Give it about 10 seconds to show the ready signal.
3. Blow steadily into the mouthpiece for 5 seconds.
4. Your exact BAC appears on screen in under 5 seconds.
If the screen reads anything above zero, you make a different choice. Your body will tell you you're fine. The number tells you the truth.
ClearSense is engineered around one job: giving you a consistent, dependable BAC number every single time. In side-by-side testing of popular personal breathalyzers by independent reviewers, ClearSense came out as the most accurate of the group.
Why "I feel fine" falls short.
Most drinkers go by feel. They count their drinks, wait an hour, order a water. But by the time you actually feel impaired, your number crossed the legal limit a long while ago. How you feel has nothing to do with what you'd blow.

How ClearSense helps
Helps protect your family before you turn the key
Two glasses at dinner can push you past the legal limit while you feel completely normal. Your weight, what you ate, how you slept, medication, stress, and the spacing of your drinks all move your number around, and none of them tell you where it actually sits.
What earlier visibility changes
Your BAC can keep climbing without a single warning you'd notice. When ClearSense puts the real number on the screen before your hand reaches the ignition, you and your spouse still have every option: wait it out, call a ride, stay another hour. Making that call before the keys move is the entire difference.

The science behind CLEARSENSE
1 / 3
What changed after using clearsense
I'm 65, and wine with dinner has been our ritual for forty years. Three weeks with this device taught me something nobody ever told me: two glasses puts me over the limit more nights than not. A month ago I would have grabbed my keys without a second thought. Now I stay at the table another forty minutes. That number on the screen is the only opinion I trust anymore. I ordered a second one for my daughter.

Ordered mine the week my golf buddy caught a DUI driving home from the same dinner I left. Three beers, a 0.09 on the roadside test, and an $11,000 lawyer bill. Mine lives in the glove box now and I check it every single time before I pull out of the clubhouse. Most days I'm at zero. On the days I'm not, I sit and read the paper for an hour. It's the same sensor the police carry. Best money I've spent in years.

I have three kids in their twenties and two grandkids with fresh permits. After we lost a young woman from our church last spring to a driver who'd been drinking, I bought five of these. One for me, one for my husband, one for each of my kids. Three weeks later my oldest called to say he'd checked himself twice and taken an Uber both times. That phone call alone was worth every penny. A real number on a screen, not a maybe. Buy one for everyone you love.

Fully expected this to be a gimmick. First test: two beers and a bourbon across three hours, and I blew a 0.07. I would have sworn on anything I was fine to drive. I've used it every Friday and Saturday for two months now and the number is almost never what I would have guessed. If you're on this page wondering whether you need one, you do. I was wrong about myself. So was my buddy with the DUI. Stop guessing.

Don't wait for the cop to do it for you.
Impaired driving is the #1 cause of preventable traffic deaths in America. And the real danger is the false confidence, because feeling fine is the very first thing alcohol takes from you.

Built with officer insight. Built to save lives.
Police officers work DUI calls every single night, and the story barely changes. A driver who was sure he was okay. A drink count that missed by two. A family in the other lane who never had a chance to react. This device exists so that story stops at the driveway.
