When my Terrova is running, my 997 SI image gets interference. (Terrova on the bow, SI transducer is on the stern) It doesn’t make it impossible to read, but it its less clear and certainly annoying.
Anyone else have this?
Any fix?
Do you have the 997 connected to the trolling motor batteries. If so that may be the problem. Change them to your starting battery. Had this problem myself.
Nope. That would make a lot of sense, but my 997 is straight wired to the cranking battery.
Try running it out of water to see if it is electrical or a vibration with water displaced from the motor
Hi,
It took awhile but I found it! Below is a video on RF interference resolution using a Ferret ring. Note: you can ask for one of these rings from HB or you can find them on the “tundra”.
Here it is:

Take care,
