Using a MagnetoSpeed Sporter for testing velocity?

I know you didn't ask about it, but the MagnetoSpeed V3 does work. I've used it for indoor testing and found sensitivity setting 7 works for .30 cal pellets.

I concur, the V3 functions well with pellets. I’ve used it to chronograph .22, .25 and .35

Same same. My V3 works with .25 & .22, need to up the sensitivity on the bayo. But I couldn’t get a reading on .17 cal, reason behind buying the FX radar unit.
