The popular "g-force" style tools that are out there are good. They are very repatable when using the same unit, and as such, make fine tuning tools. However, they are not clocks, so they will not be right on with your tracks in all cases. The good news is the error is usually very consistent and once you know what that is they make great tools.

I've got a GTech Pro. At the track:
13.22 @ 106.7 timing lights
13.27 @ 110 G Tech. I think that's darn good.

I've had one for 2 years and love playing with it....but I've had a couple of bad et reads last year at Maple Grove.....more than a half second...
Haven't been to the track yet this year...if it's still off I'll send it back for a look see...
Would tire spin at the launch affect a precise reading ???

Excessive body pitching (soft suspension) and not having the unit mounted level would be the largest sources of error with those.

Good Luck!
