The Big Red is a radar based chrono, which will not give accurate readings with small airsoft projectiles (as you've noticed.)
Use a light based chronograph instead (pretty much all airsoft chronos are light based.)
I personally prefer the chronographs made by Xcortech, CED, or Shooting Chrony.
Madbull and Guarder also makes decent ones as well.
There's at least a dozen airsoft specific models out there.
