I’m contemplating buying a Helix 9 CHIRP, DI and have a question that I’m hoping one of you can answer before I pull the trigger. When I played with the display model at the store I couldn’t get the sonar screen to zoom when in split screen with chart view. The chart side zoomed when hitting the +/- buttons but doing the same on the sonar active screen seemed to only adjust sensitivity or contrast. Can anyone tell me if the sonar page will zoom from this screen view and how to do it?
TIA
