Can anyone tell me if Gtech Pro device is really accurate?

 

from all the times that I've used mine it has been accurate. The only part that sucks other than the price is learning how to use it. The manual gives a good idea of how to use it but every once in a while you'll have trouble using it. The suction cup to stick it to the windshield sucks too.

 

Yes it is accurate.

I found mine to be somewhat accurate, but w/ the 0-60 it was a little off. I was going about 65-70 when it finally stopped counting and flashed up a time.

 

I'm about to buy one, ask gtecpro on here about it, he'll give you a good explanation
