A Review of the MagnetoSpeed Chronograph
A while back, when I was updating the
Chronographs article, I stumbled upon the existence of the
MagnetoSpeed
magnetic chronograph. Conventional chronographs involve shooting bullets between optical sensors, kind of like goal posts. The danger there is that inevitably, just about anyone who doesn't clamp their gun to a bench is eventually going to shoot the post and destroy their expensive chronograph. While there are a variety of different designs, and some of them are cheaper to repair than others, the issue is still there.
