I have a Double scan Hook 7 up front and when I use Down Scan, I get trolling motor interference. Don't get it on anything else. Any help would be appreciated.
Never test the depth of the water with both feet.

So you do not get interference when using 2D SONAR, just Downscan??? Is your power for the Lowrance unit on the cranking battery and not the trolling motor battery? If so check ground connections.

Yes, just on Down Scan. Connections are on the cranking battery and just put on a new one so ground should be ok . I 'll check to connections under the front dash and make sure they are good. Thanks...

Is your downscan a different frequency than your 2D?

I'll have to check it. I was wondering about that might be the problem. Thanks for reminding me.
