Wanting to add a second unit to the boat.I have a helix 7 di 2d and gps. My question is i heard that the garmin sonar units are better.So can i run a Garmin and a bird on the same boat with the transducers right next to each other or do i half to pick one or the other im thinking about sticking with the Hummingbirds
