Obviously you're stuck in your own thoughts, shorthairs. I don't rely on my electronics, but I sure as hell use them to my advantage. Anyone ever go ice fishing and realize they forgot their vex? did you still fish and do you think you caught the same amount of fish had you remembered your flasher? On top of that, who the hell had a tracked ATV 10 years ago? Getting to spots on the ice that you marked during the summer with a $2000 graph capable of spotting structure 200 ft from either side of the boat. These things can't make the fish bite, but I guarenteed it cuts the learning curve by a ridiculous amount.
Don't get me wrong, I love casting cranks from shore or pitching jigs onto a sandbar, neither of which require a graph. But when I troll the shore of my favorite crank casting site and find the drop off on my graph, guess where I'm setting up when I'm on foot the next time. The moment I think I've learned everything about fishing is the day I give it up. Always be a student of the game.
