Yes, I have bunches of dowsers and pendulums, but at the conference one of the vendors had one that really caught my eye:
The first thing I thought was it is a Tesla coil pendulum! Then I thought that isn't right because Tesla coils have tight spirals like this:
but I knew that it reminded me of some Tesla invention so when the conference was over I did some searching and came across this:
Tesla's drawing for wireless electricity transmitter/receiver. I haven't been able to use the pendulum outside yet because of the spring winds, but I was sitting inside and dangling it and wondering if it was a transmitter or receiver or maybe both. I jokingly thought that maybe I could call some UFOs using it. Laid it down, forgot about it. A little while later I went outside and I was just sitting there not even looking at the sky and there was a very loud plane I saw it flying over a little south of me (which makes sense as that is the normal flight path), but then when I turned back and looked almost directly overhead there was one of those damn orbs flying over. It was going so fast that I only managed one photo before it was out of view:
Seemed more than a little synchronistic after thinking about that while holding the pendulum.
