SC50 vs. SC70 satellite compasses

[thoreed]

Hello,

I currently have an SC50 satellite compass that I use as my only source of position and heading on board. I am considering adding an SC70 to use as a primary position/heading sensor and keeping the SC50 as a backup. Does anyone know exactly what the differences/improvements between the SC50 and SC70 are?

Many thanks,
Tom
