Impacted, I had my WW do a polygraph. I believe they are a useful tool but definitely not the only one. I believe they can be useful to gather information with which to use in making decisions along with other info.
I live a couple of hours north of Edmonton. I found out about this polygraph examiner through a referral from a lady that I attended a BAN (Beyond Affairs Network) group with. I looked him up on the internet and did a little investigation.
I was able to ask 3 or 4 questions. I took 10 or 12 questions in with me which we boiled down to 4 through discussions with him. My WW was in the meeting room all the time. It's very important for the WS to understand all of the definitions. Things like a blowjob is physical adultery as is a kiss.
The examiner would leave the meeting room to re write the questions and come back and discuss them again. His assistant stayed in the room with us. She would lead a discussion and said some things that irritated my WW. I think that was her intention. There was a large mirror in the end wall to the left of my WW and I. I think the examiner could have been watching reactions through a two way mirror. I didn't think of that until much later.
After the questions were finalized I was asked to leave the building entirely, not just the office, for an hour and a half. My WW was lead to the examination room which was devoid of sound or visual stimulus. The electrodes (or whatever they are) were hooked up to her to record the reactions.
The questions were asked in a very low key, slow monotone by the examiner. Everything was done for the environment to be stimulus free. I know there are some (above, for one) where the examiner came to the house. I'm not sure that environment would be conducive to the examination based on my experience.
I came back to the office at the appointed time and had to wait a while for my WW to come out into the waiting room. I got a verbal report a day later and a written hardcopy report in the mail later.
I believe it was very worth it. My cost was $575 plus GST. I think the total time was probably close to 2 1/2 hours at the office. I found the examiner I used by referral. He had a lot of experience and his website showed the kinds of examinations he had done and for how long. There was a BBB, too.
Good luck and I'm sorry things aren't going well for you.
