The dealer mounted the Ultrex heading senor on the back of the boat and the Humminbird puck on the bow next to the trolling motor/Graph. I am wondering if this is the correct way to do this as it seems my waypoints are slightly off when I mark them from the console units.
The way I have them set up on the network is the bow unit is set to read GPS from the Ultrex and the 2 console units the GPS is set to the each of console units.
My set up is 2 Humminbird SI Gen 3 at the console and 1 Humminbird DI Gen 3 at the bow with the Ultrex link
1st picture is Bow
2nd is Console Left
3rd is Console Right
