Im thinking of investing in this rather than in a transponder/beacon setup for HPDE's, seeing as it will give me more info than just laptimes and its only a few hundered dollars more... it also looks like it is better than the "GForce" thing...

 

I would love to have one of those. What a great learning tool. Just to expensive for me. I've got to get a roll bar first.

 

Most HPDEs really frown on lap timing. If they see it in your car they may not let you on the track until it's removed.
