Humminbird Interlink or Ethernet
Is the Ethernet connection on the new HD units the same as using the Interlink or is it a direct cable connection between the units? If they are separate connections, whats the advantage of one over the other? I am looking at purchasing two 788ci HD DI units or a 788ci HD DI and a 898c SI. The 788 HD appears to be able to use both connection types. The 898 only appears to accept the Interlink connection. Just don't want to throw $100 on the Interlink if it is not necessary.
