Networking? Is that really true?
Now, it seems the buzzword in chart plotter/fish finders is.......networking. But are they really? Let's say I have two chart plotter/fish finders on my boat; one is at the helm and is for navigation (primarily) and side imaging while trolling along. The second chart plotter/fish finder is on the front of the boat and is primarily for navigation (by trolling motor) and down imaging.
And let's say they are "networked" according to the manufacturer - with a network switch or whatever. And let's say both have the same Nav card. And finally let's say the two displays are the from the same manufacturer and the same model.
So here's the question, after all of that, if you plot a fishing point while side scanning/trolling, does the same plot show up on the front chart plotter/fish finder? Which manufacturer has incorporated this ability into their line of products? From what I see on the big three, no where in their descriptions are the words confirming that you can "write" a point on one and it automatically "writes" on the other. Seems to me this would be of great importance to fisherman. Am I wrong?
