What's the difference between these pumps?

I just bought a used Mag 5, but I don't if it's the Danner Supreme "Classic" or the Pondmaster. Can either model be used in saltwater? Or is the Pondmaster strictly for freshwater? Does anybody know?

The only difference on the two is the length of the power cord.
