Where to start…hmmm…


Let me just start by saying that your setup is not really a good working configuration for a bass boat.  First…mixing Gen2 units with Carbons or Lives is never a good idea.  Carbons and Lives moved to a dual SONAR circuit which gets put in “legacy mode” (disabled) when a Gen 2 unit is detected on the network.   This is not likely the source of any particular issue…just not good practice.


Based on your description of your setup here is what I would do if it were me…:


1>     Remove the Gen 2 and all 3D modules/transducers from the boat and sell them. Reason:  given already on the Gen2….and there are better options for side and down on the Carbons (AI 3n1 or AI 2n1) than the 3D system.  The 3D system matches perfectly with Gen3 units but with the release of AI transducers, the Carbons perform better with those transducers.  Better image and less compression

2>     Install a single Ethernet cable from front Carbon to console Carbon – simplify your installation and it will work MUCH better and you will have all the functionality you will ever need.

3>     Turn off Network SONAR on both units….it is not ever needed on a bass boat….for ANY reason.

4>     Make sure you have a Point 1 antenna installed (near the REAR transducer) and both the front and console units are connected to it.

5>     Sign up for our next SONAR Boot Camp (1/26) and it will help you understand exactly why I make these recommendations and increase your utilization of the tools you have.  If that date doesn’t work, sign up for our newsletter for upcoming dates.


Trying to troubleshoot your current configuration or even trying to get it setup to work as I think you are expecting is not going to be productive.  I would avoid ANYONE that tells you they can get it working the way you think you want…first they were never designed to work that way or in that configuration and secondly I suspect you may have been given some bad advice in putting such a system together….but…


I am happy to help any way I can….just give me a call when you have time if you like.



Very Interesting!

I find it ironic that his first words were “remove it all and sell it”. I do agree it is a bad idea to mix different gen units on a network or a backbone. Different units have different sw versions and different features and seldom work properly when networked together. I also agree that Network Sonar is a bad idea. I still think you could get what you have working and working well if you would get rid of the gen 2 unit or replace the gen 2 unit with another Carbon unit and redo your Ethernet network set up.

Mike , i would try downgrading software on 3D box if you upgraded to the 19.2. I was told dont if you use carbons. And go back to 18.3. I replied on thread below. I wouldnt take the 3D box out till i tried that. Do a hard reset on carbons on dont reload setting. Start over with your data and pages favorites.
