MGnito vs Labradar variance.

[chamberbrake]

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.

Your magnetospeed is at muzzle
What distance is your Labradar set for?

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.

Compared Magnetospeed/Oehlere 35P/LabRdar

Chrono Comparison Test: LabRadar, Magnetospeed, & Oehler 35P « Daily Bulletin

We see comparison tests of cars, cameras, and other hardware. But how about chronographs? What could we learn by setting up three different chronographs, and running a 20-shot string over all three at the same time. One of our Forum members, Randy S.
