Hello fc, my hot lapper broke after 10 years of service. i have checked and found aimport's lap timer and read about it's functions and ordered it. anyone here have used this unit? http://www.aimsports.com/products/tg/index.html
If you are running with a video camera you might chose this one. http://www.trackoutdesign.com/gbox/ FYI, I have no relationship with the company etc.. I just like seeing the g's and my delta times in real-time with my driving video.
