I picked up a Helix 10 SI over the winter and I’m going to install the SI transducer this weekend. Does anyone have any experience with 2 transducers near each other? I have GT54 transducer from Garmin currently installed on a transducer plate on the transom. I was hoping to get away with not drilling anymore holes in the transom. Am I better off just installing it on opposite side of the transom to avoid interference.
