I'm considering adding a Garmin unit and Panoptix. I currently have all HB's with 360 on boat and I'm not getting rid of them. Just looking to add a basic unit and a Panoptix transducer. From my research, I'm thinking something like a 94 series and a PS21. Would the 9" screen be adequate for viewing the Panoptix? I want to stay cheap as possible with still being able to see the screen ok. Any advice is appreciated.
