Share GPS position, waypoints, and routes between two Humminbird fishfinders in real time. Daisy chain InterLink with other modules to create a digital network on your boat. Humminbird Fishfinders not included.     The AS Interlink is Humminbird's early version of Networking.  It shares only GPS position, waypoints, and routes between two older version Humminbird fishfinders in real time.  Daisy chain Interlink with other modules to create a digital network on your boat.  The Interlink product should only be used when one of the two Humminbird units is not Ethernet capable.  The Interlink will not work with any of Humminbird's 2014 products in the 11X9ci, 9X9ci or 8X9ci Series of products.  If you have one non-Ethernet capable product and one of the 2014 Ethernet products, you will be unable to network.   When both Humminbird units are Ethernet capable, you should be using our Networking cables, plus our 5 Port Switch (depending on what products you plan to network).  See our Network Cable Connection Chart to confirm which products are compatible with the AS Interlink.
