We have been using the I-Lap system at DRC for over 2 years now with great results. We scored our 2008 SEMOWRCS with it and had no problems, we have had both the old and the new system and we love the new system and transponders. Craig is right there with customer service and setup issues from the start, thanks! It's nice to have a lower cost alternative to AMB systems which are way out of our price range...
We use Alycat scoring software...
