used the Precise Time device?

you hook it up to your whistle and when you blow the whistle (Fox 40 only) it stops the clock?

also has a button on the bottom so an official on the floor can start the clock ...

Those of you that have used it, how did you like it?

I have used it 3 times. I love the system. It is not perfect, but I liked it a lot. It did get me to pay more attention to the clock that I still do now.

Peace
