The electronics as several have already said are a tool. They in no way give an "unfair" advantage. My electronics have not caught a single fish. Its still about lure, line, rod, reel and human input that catches fish and that will never change. Electronics catch as many fish as an outboard motor, trolling motor...etc. claiming that electronics are becoming "unfair to the fish" is a ridiculous statement really. Is a modern centerfire rifle unfair to a deer compared to a flintlock muzzle loader?
