How is that system working for you. I am new to this but it is my understanding you can view wavepoints on both units and when you save a wavepoint on one it saves it on the other also. I have a 520C on my dash. Thinking of buying a 520C for the front.What other features are you able to do when they are networked as compared to hooked up seperately.
Thanks for your help.
Yes they share waypoints and external GPS. You can use either transducer or both use 1. I like mine. I fish my crappie condos lots and I can run to them, but before be poking around trying to find them with the trolling motor. Now I don't have that problem!!
