Finally.........

I was just kidding in my opposition to PT (hence the smiley face). I'm definately aware that you will always need a timer at the sideline - just this way, the coaches can't blame me when their player doesn't make a last-second tap before the horn

From my understanding, PT makes its units separately from the scoreboard/clock. They just make an interface that replaces the start and stop buttons.

I know the system is keyed into the specific tones of the Fox 40 so people in the stands can't whistle to stop the clock. I wonder if anyone has tried to bring a Fox 40 with them to do something like this.
