Side imaging

If you plan on buying the unit for SI and can afford it, I would lean towards a larger unit. I'm sure the 5" units (798) are nice and do everything the larger units do but I could see where it would be frustrating on the water trying to decipher images on the screen (especially with the split screen modes). I went with a 898 over the 798 for that reason after looking at them at the store.

I have the 1197si and it's the best investment I ever mad it's my eyes under the water. It's amazing what this unit can do.

You're right, We have a 798cisi and with the split screen on, you are limited. Go for the 1197si if you can. As far as the features of both, it is a great fishing tool that will help you catch more fish. Good Luck

Definately go with the bigger unit!!!! They have more power than the smaller - trust me I have had both!!!!! I know the price is a little higher but if you are going to invest that type of coin on one get one you will love instead of feeling like you settled - Like I did!!!
