For the record, I am by no means a guy that treats my graph like a video game, drop-shotting to one arc on the screen in 40 feet of water. But I do like good electronics that do all the modern jobs. I run two Humminbird 998c HD SI units (a moderately sized and priced model), one in the front and one in the back. The transducer for my front graph has what's called a universal transducer to make it look like its part of the trolling motor head. This helps me avoid cracking transducer heads off on the bottom when fishing shallow, and I'd say 50% of my bass fishing is done in shallow water. Otherwise, my front graph is linked to my back graph so that the GPS waypoints I mark driving at the console pop up on the front graph as well, and vice-versa. As for new and advanced features like side- and down-imaging, I only use them about 10-15 percent of the time, but those times are usually the crucial times where that technology can make or break my position in a tournament. As an example, if I find a school of fish and they move, relocating that school is much quicker and easier with side- and down-imaging. All of that said, what's most important in terms of electronics is never becoming completely reliant on them. Sometimes being able to position the boat by lining up features on the bank or using your eyes to detect bottom transitions will get you into more fish than the best units out there.
