Does it make sense to buy the Humminbird Solix with Mega SI and DI for the front of the boat if you can't use the transducer on the trolling motor because of the distortion of the SI and DI when using the trolling motor? Should you just buy the Solix Mega chirp instead and link it to another Solix at the console with Mega SI and DI and use that transducer on the transom?
The distortion that I'm familiar with, being a humminbird user, is from using the incorrect DI transducer. The DI units, helix and core units, come with a transom transducer that you need to mail back to humminbird for their exchange program. They will provide you the correct trolling motor specific DI transducer, and that has eliminated all interference. I had a 1199, SI unit, on my bow once and never got interference using the HDSI transducer on the trolling motor. Of course I always run direct power to my units, straight to the battery.
