I think being within 2 hundredths is pretty damn close for a $150 device. I understand that in competitive racing 2 hundredths is a lot, but not to most of us. It’s especially useful for someone like myself thats 2 hours from the nearest track. It’s not like I’ll run a 10.2 with the dragy and then get to the track and see I only run a 10.8 or something obscure. Plus you can see stats like 60-130 or whatever other times you want that you can’t get from the track.Its a nice tool, but its really not that close. 10.19 and 10.213 its a big difference.
Definitely the 60ft dont compare either.
Call me old school but the only thing that matters to me is what your time slip from the track says.
