I’m running a 798 SI as my second, but have a helix 7 did I going to swap in, and figured I’d do the second ducer if it was worth it. Thanks for the input!

My helix has the option to split screen of left and right si…then run my maps on the other finder. The transducer is on the right side of the boat. It seems the Left SI is always a worse picture and definition. Like maybe interference from the cavitation or motor? Either way, thinking about putting a second ducer on, but didn’t really know if there’d be a difference
