"This is the chronograph I use and it is an excellent step up from other, more traditional models. The first chronograph I ever used was when I was a kid, the old shoot-through-the-sticks type model - it was my Dad's. The *very* first time I got behind it, I put a bullet hole right through the guts of it! Dad was pissed to say the least! I had CRPTS (chronograph related post traumatic stress) from that day forward until the day I started using a Magneto. They are super accurate, reliable and you never have to worry about shooting a hole through the center of it!" - JSharps
