I have a 898SI and an 898DI. I got them both pretty much at the same time, the 898SI is the american model and the 859DI is the international. I have them both mounted on the console and the transducers mounted pretty close at the back of the boat.
I planned to be a smartypants and run the SI at 83 and 855, and the DI at 200 and 455, to reduce interference. Anyway mounted them all up, and had the first day on the water today. Under test, I was getting some interference, so had a fiddle with the frequencies. Anyway to cut a long story short, i ended up getting the 898SI transducer to feed both units (over the network) to see how it would go.
When I flipped thru the screens of the DI model, I had side image screens? Is this normal?
