My experiance with side imaging units is limited, however I am not impressed with the picture that comes back. Take away the imaging and the humming bird graph is the best on the market, the gps and the screen size is a great plus. And there is alot of other features that are really nice. Depth shading is really nice. It will allow you to shade a certain depth, say 25 feet, the. It shows the areas of the lake that is twenty five feet deep. It allows you to focus your attention to one certain depth, and shows that depth over the whole lake.
You can't beat the taste of them ole fried SLABS N TATERS!!
