Number of Fish Finders on a NavNet 3D network

​Up to two Network Fish Finders can be installed and controlled in one NavNet 3D network. For example, both the DFF1 and the DFF3 or FCV1150 may be installed on one vessel and the operator may select which one to be enabled as the echo sounder source.  This allows the vessel to change geographic regions and instantly select the optimal echo sounder source for a particular fishery.
