MGnito vs Labradar variance.

I'm running both a magnitospeed and labradar to see their differences. The mag runs consistently 20-25 fps less than lab. Anyone experience this and have thoughts on why ?

Thanks.
I've done the same thing with my Sporter several times and the numbers have always been within 2-3fps of each other. I personally know 2 people who tried it with their own chronos and the results matched mine. If you have the Lab set to acoustic trigger, it automatically calculates the MV. If you have it set for DOPPLER trigger, it calculates the velocity from when the radar waves first pick the bullet up, which may be 10yds or more downrange and it then gives a SLOWER reading, not faster. It sounds like you may need to test them against a third Chrono to see which one is wrong.

Yea
My sporter is always within a few FPS of the Labradar.
