I see posts about not doing this. Are there not some kind of ferrule that will clean the power line up? That beautiful 12 volt power right where I need it, I wanna use it. What says the hive?
I think the issue is what happens when the TM runs the battery down and then you don't have your fish finder or vice versa. The TM will draw a lot of power away from the battery, depending on usage.

Ferrite rings/coils likely wouldn't be enough. A TM draws a massive amount of current compared to your finders. For most folks, a cranking battery handles three or more graphs, pumps, and even shallow water anchors.
I run one group 31 Duracell AGM for cranking and electronics. While I don't have shallow water anchors, I have had all three graphs on as well as livewells running and for a while a Hydrowave for 8+ hours and never had any issues starting. In fact the cranking battery usually completes charging long before the TM batteries.
The interference from the TM will kill the screens on newer electronics. Most manufacturers specifically say to NOT use the same batteries. That will probably void your warranty.
I moved my Talons and aerators to my TM batteries to conserve cranking battery.
