ProChrono Digital Not Reading?

[Hosted]

I recently bought a ProChrono Digital after reading some great reviews. Today was my first day out with it and it would not read no matter what I did shooting 223. It was overcast and I positioned it 10-15 feet away. I tried with and without the diffusers, close to the chrono and high, and putting lines on the bullet with a sharpie but it never changed from 0. I'm going to try again tomorrow in the sun and see if I can get it to work but wanted to see if anyone had any ideas or if I may have gotten a defective one.

This would be a gross check for functionality but it should tell you if the electronics work. Remove the screens and rods and swing a broom handle over the top of it. You may only get 100-200 fps (depending on your swing) but it will be a reading.

Maybe a low vel 22 rim fire. Sometimes I have a little problem with mine if it is really cloudy, but most of time it works great.

Sorry for not updating. Shortly after I originally posted I did what itchytf said and it registered just fine. I must swing a stick much slower than you though. I have since used it many times without any issues. I need to go back to that range and try it again. Looking back on it, there is a tree behind where I was shooting. It was not above me at all, but maybe I was getting some kind of shadowing from it or something. Either way, all is good now!
