G-Tech Pro

I was thinking of picking up one of those g-tech pro's. I was just wondering if anyone has any experience with them and how they feel about them, are they accurate?

Lol...oh man...don't get me started...that's what I use for my times, and I got flamed like there was no tomorrow on maxima.org...everywhere I go except there, I get mixed opinions on the thing...I think the consensus is that the G-tech is a good estimator, but is no substitute for a time slip.

Oh and one more thing...it says in the owners manual that the trap speed you get is 2-3 mph on the optimistic side...don't know why, but that's what they say.

don't get it, it's worth it to actually go to the track
