I agree Tally. Fish use their lateral lines much more than their eyes. Actually fish will detect prey with their lines first; their noses second and the eyes don't come into it until they get close to the prey.(and that distance can vary depending on the water).
How many times does a guy throw a spinnerbait to one spot 4 or 5 times before he gets bit. I have to laugh when I see guys make one cast to a spot and then move on if they don't get bit. I've come right behind them and caught nice fish in the same spot a couple of miutes later. It takes time for the fish to identify where the sound is coming from and then to get there to see what the heck is in his territory.
I'm a little off subject here; sorry. Anyway, what I'm saying is that fishing really does not have to be complicated; lights, buzzers, electonic swimming lures, etc are just bling bling for the dum dum.lol
