I'll disagree on this...you fiddle around with a hand held trolling motor in the wind while I spot lock my Xi5. I'll be doing a LOT more casting than you. Not to mention the hands free operation of being able to follow a weedline or creek channel.
I WILL say that technology has made a lot of mediocre fishermen better...but it won't replace knowledge and time on the water.
While I do not disagree it makes life easier, I have seen many fisherman who "look the part" with all the bells and whistles who are just posers. They could't catch fish before, and they do not now. Not one piece of technology will replace natural instinct and ability to make changes on the fly. You may make more casts, but that doesn't mean you are making more quality casts. That being said, if you have the money to blow on a fancy TM or graph or any piece of expensive fishing equipment, go for it. Companies will continue to drive prices as long as we have people to pay them.
