Wayne,
I currently have a Helix 10 G2n sonar gps at the bow. Im going to be purchasing a Helix 12 g3n mega di and also putting it on the bow for the 360. I see you can have the 360 along with another transducer connected to the helix 12 as long as you have the correct Y cable. My plan is to run an external transducer on my ultrex along with the 360.(Both connected to the 12) My question is while I’m running the 360 on the 12 will I be able to see sonar and or the mega di on my 10 at the same time the 360 is running? The 2 units will be linked together.
