I have the magnospeed, but have never used it. It would require me to push too many buttons. Maybe I tried it once in the backyard. Strapped some gizmo to my barrel.

I am still on the pro chrono. At 2500 feet elevation, sometimes the sky looks black and the chrono will not trigger. I turn it sideways and point it at a box and shoot between them.

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway
The man who makes no mistakes does not usually make anything.-- Edward John Phelps
