In my honest opinion if you have the money to upgrade do so, but where do you draw the line on the digital scale of technology. I understand the GPS and the L.E.D.fixture on a depth finder, but this 3d imaging of structure is ridiculous...you mine as well show how big the bass are and where they are located under the structure, I know someone is gonna say, "well depthfinders don't catch fish,the technique or the right set up does." Yes, but where do you draw the line from taking the sport or fun out of fishing...and I know the answer is, "well just don't get the equipment." I just need your thoughts.
