if the paradox is horizontal, and the chrony prefers readings directly "above" the sensor, couldn't you lay the chrony on its side and shoot next to it?

Or, easier, cant the bow over horizontal...

joachimM:
Will try!

I also have an air rifle with which I can test whether or not I have enough light on these cloudy grey days. At least those pellets should shoot straight  :-M

DC:
It amazed me that I could have so much trouble trying to get arrows to work and yet if I used my pellet rifle(that I hadn't shot in 30 years)it registered every time. On my Chrony the sweet spot is only 3/4" wide apparently and when you shoot like me that's a really tiny spot.

willie:
hmmm  3/4"  isn't  a very wide window, I can see that being a field of view sort of thing with the sensor
how tall is the window? does brighter light make it taller?

DC:
I don't think I've had any problem with the height of the window. That said I'm not sure how I would know for sure. It's the shadow of the arrow that the thing detects so until the height gets to be enough that the shadow fades I don't think it's a problem. You have to keep in mind that these things will detect a bullet going close to 10,000 fps so it doesn't take much to trigger it. I would think that if it didn't trigger then the arrow didn't go over the sensor.
