Friends

Simple, One-Touch Operation

The S80 is easy to use - insert the two AA batteries that come with the product, and it's ready to test. When you press the start button, the BACtrack S80 counts down for approximately 10 seconds, preparing the system for a breath sample. When the countdown reaches zero, blow steadily and continuously for at least 5 seconds. If a sufficient breath sample has been taken, the user's estimated BAC is displayed on the screen.

Reliable Performance, Accurate Results

Despite its small size, the BACtrack S80 packs serious technology inside its black plastic casing. There is a miniature air pump inside the S80 that activates at the end of each breath sample. You can actually feel the 'click' during each test. This proprietary internal sampling system ensures that a precise breath sample enters the alcohol fuel cell sensor, and is one of the reasons why the S80 provides trusted, accurate results every test.

Test Yourself, Friends and Family

With it's easy to read LCD screen, extraordinary battery life and six extra included mouthpieces, BACtrack S80 is perfect for testing yourself as well as your friends and family. Take it with you wherever you go and gain peace of mind while keeping your loved ones safe with BACtrack.

4.0 out of 5 stars Consistent results and easy to use...
Reviewed in the United States on January 31, 2011
"Better safe then sorry", is the reason I picked up the S80. I used the analyzer a couple of times and the results have always been consistent; even with three people using it with different BAC during the same period. The S80 comes with it's own case and 6 individually wrapped mouthpieces. So it is best to pick up the 10 pack of mouthpieces [[ASIN:B001UE7D0U BACTRACK Select Breathalyzer Mouthpieces (Pack of 10)]], because as soon as your friends find out you have a breath analyzer at a party they are going to want to use it. Also, you should get an extra set of battery and put it in the case, just in case the day you want to use it and the batteries are dead.

According to the instructions, do not use breath analyzer until it has been 20 minutes since the last drink/food has been consumed. Following that rule, should provide you with accurate and consistent results.

Quality:
The S80 is made of plastic; the type of plastic that appears it will not fare well during a fall on concrete. Just be careful to who you hand this too (if the person can't stand, he probably will not be able to hold your $150 investment). The case provided is really nice; it holds the instruction manual and S80 unit. There is a pouch inside the case with a zipper that you can put the mouth pieces (I have 16 pieces in mine) and extra batteries. The case is (6"x4"x2").

Background:
Majority of the breath analyzers that Amazon sells contain two types of sensors; semiconductor-based or fuel cell. The semiconductor-based typically cost less then hundred bucks and are known to be inaccurate and inconsistent with it's result. The fuel cells provides accurate and consistent results, but the breath analyzer with that type of sensor cost a lot more (but less then a DUI). The S80 has the fuel cell sensor.

With all of these sensors, they do require to be calibrated once a year or every (200 to 300) tests according to BACtrack. BACtrack charges $20 to recalibrate. It's competitor AlcoHawk charges $29 for it's fuel cell version.

(Update 12/11/2001)
Be sure to tell the user to take a deep breath before blowing (I just taped a note on the analyzer as a reminder). We used this at a party and my results were accurate, but some people's results were questionable. It turns out I forgot to tell them to take a deep breath (provide a deep lung sample), as described in the instructions. After a retry with a deep breath, the results were more in line of what we expected.
