Ok so have grown up fishing lake chickamauga but never that serious. My young kids have shown an interest in fishing and want to be able to find fish more quickly. I went with a buddy crappie fishing who had live scope and wow what a game changer. Not sure I want to fork over the 3k it seems like it will take to get live scope. School me on what electronics I need to be more efficient at finding new places to fish especially schools of crappie and blue gill beds for the kids. Side scan, down scan, live sonar, etc what's a good place to start for reasonable money or should I just get the Garmin live scope and be done with it.
