I understand that you already have a chrono' and I apologize for suggesting a chrono' that will do everything you want and then some. It has capabilities that no skyscreen unit has but also can't do some things that a skyscreen unit can. But since having mine I have thought for even a second to set up my CED unit. It sets up in minutes and can be used in the rain covered with a clear poly bag. Use the separate power unit they sell, or get your own. I did the latter. I have never regretted the power cells purchase or the purchase of the Labradar.
Yeah, I know it's expensive, but if you use a chrono' a lot it's worth every penny.
It saves data in .CSV format so many spreadsheets can import it directly. Mine can't but I just open the text file with Notepad and replace all the semicolons with commas (find and replace function) and I'm in business.

Tips:
Choose the velocity window correctly or get funky data.
Don't get it or the power cell wet, but poly bags are inexpensive. So far mine has been "rained on" twice protected by a thin poly bag. Don't get the unit itself wet. Yes, I checked with the Labradar people and they gave the poly bag trick.
Get a sim card for it. Then plug the sim card into your computer to work on the data. Is a sim card required? No. But to save data it is.
There is also a phone app for it but since I don't have a smart phone I can't help there.
I absolutely LOVE(!) my Labradar!
The manual is online.
