I acquired a Helix 9 G4N MSI head unit. I already run a Garmin 106 and 93 with a GT-56 transducer. I am wondering if the addition of an XM9 Helix transducer on the opposite side of the transom would cause frequency issues with my GT-56?
I’d love to run the Mega SI and LakeMaster mapping and then pair it with Garmin 2D and LVS. I may be over complicating things.
Anyone have experience with multiple transducer?
