Personal Breatho

[gts-t 4 life]

Looking at buying a personal breathaliser from autobarn for $160 has any one used them befor and do they work well.

[predator]

We bought one for a mate once for around $100..

Wasn't too accurate at all (said you were sober after 10 drinks). Maybe they've got better, or it was just a shitty one but I wouldn't rely on it.

[gts-t 4 life]

yer read up on them and i dont think i will buy one now ay

[gtrchick]

lol my mate bought one of those servo ones, it worked ok, then it shit itself.

[dangerous_daveo]

SDT sell some one use ones from memory. They seem to be a bit more accurate.

Easy way tho. If you are going to drink, just dont drive. Its not worth the risk of the fine, your life, and most importantly someone elses life.

yer was looking at geting it so i can c if i am over 0.00 in the morning or the next day

$30-80 on ebay for exactly the same quality products as you find in the stores for 100-150

i bought one for my brother for xmas last year.. cost $30 and works quite well..

from what i've seen/heard, they're about as accurate as a blind person with a rifle, trying to hit a bullseye at 800m

Most males are able to digest or dispose of alcohol at a rate of usually 1 standard drink per hour, or old saying for men 2 standards in first hour and 1 standard every hour after that usually keeps you under .05, to work things out better, if you have roughly on a good round 8-10 jimmy cans at i think 1.9 standards your looking at 17 to 20 hours Minimum to dispose of all alcohol from your blood stream, thats from the moment you start drinking, It is also on a base that if you eat usually helps but is still within your system, 1 standard drink is usually the ammount that a persons liver can process, that is a person that is healthy and has a healthy liver of course, but as above if you going to drink DONT drive.

will it still be on ya breath 20 hours later or just in ya blood stream

[Konrad]

will it still be on ya breath 20 hours later or just in ya blood stream

short answer : yes

long answer:

its in your breath because its in your bloodstream (lots of blood flows through your lungs otherwise you'd die for several reasons), but the residue alcohol in your mouth will evaporate after you take your last swig, best guess this would take no more than 30min

[Col-GTSX]

Would it be fair to say the fatter or bigger you are the more alchol it takes to read lets say 0.05% because you have more blood in your system than thinner smaller people.

So in short if you give me 2 coronas in an hour i might read about 0.05%

but

If you give say squizz or mud 2 coronas in an hour he might read about 0.07%

[Konrad]

yep spot on... more body mass (more blood= more 'fluid' to act as a solvent) means that for a given dose of something it will be diluted to a greater amount. Also for meds your fat percentage is very important as drugs can be retained in fatty tissue, but this wouldn't apply to alcohol i'm sure.

Real world example - if col and a old lady each consumed a yard glass how many of them would it take to change a lightbulb? if you found that funny you are a skinny bastard that has had 1 beer with dinner and are intoxicated..

the end

my $0.02....

i had a $30 one from ebay. It would work and read pretty close to what we expected ONLY if you blew across the sensor the right way. You had to blow through the plastic slits at the right angle, otherwise it'd read nothing. It'd either read accurate, or fully OK to drive.

Then one day i opened it up to see how it worked. I saw a button on the inside that i hadn't seen before. I pushed it and it has never worked since I think it was the "callibrate" button and it lost its factory callibration.

[prego]

lol^^

well imo simple if your going to drink get a lift or catch a bus

[predator]

not sure if the weight thing is strictly true..

It's only a rough guide the 'x drinks in x hours thing', and will vary person to person - it's not just weight, but that may be a factor, amongst many others (diet, metabolism, fitness levels, how much alcohol you usually drink, cultural, etc).

[Einstein]

get one of those breathalyser immobilisers

you have to blow under 0.05 or your car wont start

edit: and btw the weight thing doesn't do shit for alcohol, it's the quality of your liver and how well it metabolises alcohol, and if anything else is distracting it at that current point in time (meds, drugs, certain foods/liquids)

i'm on some funky prescription meds, and from those i can tell you that it all comes down to the liver =)

[Punisher]

I have one of the Alcohawk Pro Breathalysers, it is extremely accurate as far as personal breathalysers go. Its actually rated better than the Australian Police ones. It is still only a guide though, any reading won't mean shit if you get pulled up and test over.

Halifax and General will also recalibrate them (recommended every 6 months)
