Just a taste. More to come, but who knows when! Here is some of the data output from the chrono with the factory software.

My first test with the Kurzzeit PVM-21 Chronograph.

When the PVM-21 is connected via USB to the notebook, every shot is automatically added to the currently open series.

I'm actually really starting to look forward to getting out to the range and putting something a little more substantial through the light screens than some paintballs and pellets. It took most of my Sunday to get the PVM-21 to communicate with my notebook and the remainder to figure out the software that comes with it.
 
If my math is correct, we put 219 rounds through the PVM-21 today. Had about 3 that produced an error and about 5 that I put too high above the light screens to get a reading.

We orginally took turns shooting our previous chronograph but this time it was just me shooting through the PVM since I was the one that bought it and buddy is too cheap to replace it, if he shot it. Near the end of the range trip my hands were starting to get tired, it was hard resting the pistols and doing my best not to hit the chronograph. My focus and detirmination led to some of my tightest groups today. I was so focused on not shooting the chronograph I didn't log my success.

I did learn, however that my Sig 1911 prints the tightest groups when compared to the other pistols in the list.

Looks like a lot of data can accumulated. I keep my cronographing low tech and write down each shot, to much info gives me a headache.

We shoot a lot, with our old chrony we had scribbled notes all over the place, occasionally mixing up the entries. It's nice to have this much data as you can pin point issues. The next test will be of more specific load groups and ladder testing.
 
I think that is excellent, I hadn't heard of this device. As is, I am filling up my Chrony memory then manually entering the data into spreadsheets. It has occurred to me more than once that it would be nice to download the data from the Chrony, but that given the state of measurement digitization it must be possible to set up a laptop as the brains of the chronograph, and leave just the skyscreens downrange. Nice to see that someone has built one. What did this setup cost you?
 
Said and done, $900.

Edit: I wanted to add that we were testing as a team. My notebook computer hooked up to the PVM, my buddy entered the information into the database for each series test we did. As you can see by the time stamps we only spent about 1.5hours. It took me about 10 minutes to get fully setup at the range. If I remember I'll post a walk through.
