Thanks, I bet I've been to that site fifty million time and didn't realize it was there. I still a little confuse because I don't see how these cams do what they say. Not that this should ever happen, but if you had one limb maxed and the other all the way down, how can they keep time. I guess I just need to get my hands on one and look at it. Thanks for the help and sorry for the lack of attention I payed. Guess If I wouldn't have been so buisy looking at the gaurdian I may have learned something with out someone haveing to tell me. Thanks again
