http://www.trackmateracing.com/shop/en/ ... or-windowsBob there are a lot of different systems for, timing out there, and you will get a lot of decent advice from those that have them.
Some like the Light bridge, some the dead strip and others that use infrared in the slot itself.
I suppose they all have their pros and cons.
Im not familiar with the software you are using but someone else here might be.
My personal is the dead strip, I have it on both my big track, and my test track and they havent let me down yet. Themlink, at the top is o emsite that makes pretty good stuff in different formats, dead strip, light bridge, reed switches, and ifrared slot sensors.
Just an example of whats availabe.
Cheers
