I took a poly for a big secret government agency.  After spending so much time on this site, I was scared that I would be given a "false positive".  So I decided to employ the breathing technique countermeasure, by holding by breath ever so slightly during the certain questions.  Of course, I was interrogated and at the end of the session the polygrapher told me that he knew that I was "holding my breath just like they tell me to do on the internet" - were his exact words.  I was caught, busted, and my heart sank.  Of course, to save face, I denied using countermeasures just so that my denial would be on record.  But in my heart and mind I knew that I was caught.  Those pneumatic tubes they put on your chest are very sensitive and I'm sure the polygrapher could see every breath-hold that I did.  My dream job floated away after that polygraph.  I would advise everyone, if you must use a CM, use mental CMs.  Nothing can read your mind.  But your breathing, tongue bitting, ass squeezing, and other physical activity can be read.  With the sensors they put on you, including the seat sensor that can detect butt squeezing and farts, the mirrors, the high resolution cameras in the room, and the fact that your polygrapher is sitting right next to you to watch your movements, don't even try to change your physical activity if you can.  I tried to use the CMs that I used on Antipolygraph.org and I was busted.  I'm so ashamed and have to carry this for life.   

I'm not a polygrapher.  This is a true story.  Trust me, the polygraph machine from Layfette Instruments that is used is VERY sensitive.  Those tubes can tell when  you don't breath even for a split second.  And the fact that the polygraher is staring at you, don't even think about tongue biting or nothing stupid.  There is a sensor on the seat, so don't try the anal contraction.  I was busted.  I thought they were just accusing me of CMs as standard procedure but in the end I was rejected and got a statement saying that was why.  They knew.  I denied it.  But they knew.

busted,

Which agency polygraphed you? What questions were you asked? On which ones did you hold your breath?

Stefano, 

You are using the same tactic you accuse polygraph examiners of using.  If the CM did not work, you used them incorrectly.  (If you passed while using CM the examiner was not properly trained.)  Why not just admit CM's are detectable unless you have had EXTENSIVE training in their usage.

Nearly all polygraphers well tell you they can detect mental manitulations during the test. They can't. They are only guessing and try get you to cop a plea. The problem is that their guessing is accepted without having to produce any factual, hard evidence. They are the only and final word.

Because that would not be true.  They work, have a scientific basis and should be used.  I am not aware of your use of CM's and cannot dispute anything you may have encountered, nor can I attest to your claim.  

I have been able to detect physical countermeasures on numerous occasions, they are evident when used.  I cannot comment on all uses of mental CM's, I am sure they have been used successfully by some.  Experiments I have conducted (non scientific) with mental CM's demonstrated to me that they are difficult to detect and impossible to prove.

TLBTLD does not recommend anal contraction as a countermeasure. In fact, given the non field-tested sensor on the seat it advises against it.

They did not 'know' you were using countermeasures; your polygrapher took a stab in the dark, rattled you and you folded.

On my first polygraph which I successfully passed using countermeasures the polygrapher used one of the counter-CM tests, so it was obvious he suspected something. I kept my cool, finished the test and 'passed.'
He didn't 'know' anything though I'm sure he had his suspicions.
