I just heard from my vbox buddy that the new vbox sport runs at 20Hz which means it's twice as accurate as the old unit, and that makes it a good buy.
He's also confirmed with the guys at racelogic that it's compatible with his online vbox analysis software at
www.vboxtools.com. So if you buy this unit, you'll have a great unit and your 60-130's can be verified online through that site.
