Magneetospeed or traditional chrony

[mgunderson]

Interesting idea, but have you checked it against another accurate chrono? I would assume that the electronics are designed for the bullet 'shadow' to pass over a specific screen separation. The length of time between passing over the first screen and the second determines the speed. I know when I once failed to completely unfold mine I was getting 300-400 fps faster readout than it should have been when completely unfolded.

Checked it against. Base chrony, magneto, KVM, and LRadar. When you split the chrony you can screw an unmodified unit in the middle. Two read outs is better than one.

It did take me a few adjustments to get the distance between the screens correct.
