Bruce,
Take a look at what TraqMate has to offer. Their system has, IMHO, a lot more to offer in the areas of data collection and analysis. It is easy to install but takes a bit of experience to use the info effectively. The MyChronLight TG system that comes with the ACR ******** appears to be more limited in it's application. Both systems have websites which would be worth while to look at before you make a decision.
