rubble Posted May 29, 2018 Report Share Posted May 29, 2018 Considering replacing my Garmin Echomap 73 SV with the Hbird Helix 9 G2 Mega SI. Main reason for the change is so I can network with a new unit at the bow. I may keep the Garmin for now so that I can still follow old trails and have all kf my waypoints. 1.Will a second transducer create interference or other issues? 2.Can you run two side image ducers at the same time? 3.I’ve read that the Helix struggles to read depth when moving faster than 10mph. Has anyone noticed an issue with that? Link to comment Share on other sites More sharing options...
Bamaskeet Posted May 29, 2018 Report Share Posted May 29, 2018 Transducers that broadcast around the same Hz will interfere with each other. Link to comment Share on other sites More sharing options...
