GeorgetwalkerJr, I will second the need for you to purchase a chronograph that is separate from the screens - that way you can record the results safely from your shooting bench, and if you accidentaly hit the screen, the cost is a few bucks for a piece of plastic, not an entirely new chronograph! By the way, I have an old original Pact - still accurate and works fine! Check out eBay, you will be surprised at all of the great reloading gear listed there.
