All,
Noticed a lot of posts concerning side imaging here a couple links to sites that have some really good info on proper settings, transducer mounting and adjustments. These sites helped me dial in the 797 when I bought it a couple years ago. There are some good SI images of cool stuff on several NC lakes.
