Maybe your background in surveillance is what led her to research countermeasures and discover RF Detectors? I mean, most people do not expect to be bugged, and thus aren't looking into countermeasures!
Then again, I would like to think most people aren’t cheaters, so don’t really care who knows where they go.
Tech equipment seems to be a dry topic so I never discussed that with her. She may have seen the box the tracker was in because after I bought it, I didnt plan on using it, soI really didn’t hide it. I know Om is a serial cheater so he may have suggested it, but I got the impression it was hers.
