If the Question is how do I use my electronics to assist me in fishing, then let me preface the answer with how I have my rig set up. I keep a flasher on the transom and a LCR on the electric motor. My GPS is a stand alone unit. This configuration is based mostly on economics although with unlimited resources it would not change much. The flasher runs when the gas motor is running and I'm getting real time knowledge of the depth and bottom type,ie: rocks, mud, weed. I'm looking for changes in depth or bottom type. If I want to check out a point or cove, I can do it quickly with the flasher. If I see a break or jumps in depth that I want to check out in greater detail. I 'll do it with my trolling motor and the LCR. For example, if I come to a point and I want to map it quickly I criss-cross the point with the flasher and the big motor and drop bouys at the 12' depth line. I'll set out 5 bouys and back off and look at the spread from a distance. It's like looking at a contour map. If one bouy seems to be in or out from the general spread, then I have a point or a ditch on the big point. This structure on a structure is the spot that I will search with my LCR on the trolling motor. I'll set my waypoint off this small point and next time I want to fish it the GPS puts me close without running over the spot with my gas engine. This is a general explanation of how I use my electronics. Tactics change with conditions and the presentation you are using. Even with the GPS or the LCR if I'm vertical fishing a rock pile or wreck I set a Bouy as a reference point. The tools all work together and remember the repeatability of GPS is not that good. It will get you close but not exactly on the spot as LORAN did. Without the bouy the wind, wakes and just the act of landing a fish will cause you to lose your bearings. Keep a log of the waypoints as well. You can record little observations and notes about the spot. I try to record land ranges and the lat/lon numbers for every spot too, so if the unit breaks I haven't lost the spot forever. If you need more just ask.
