I am thinking of purchasing a Lowrance Elite 4 HDI with the down scan imaging. I have never owned a fishfinder before and never really felt the need for one. I have a 1548 G3 Jon Boat. I have mainly fished local bodies of water that I am confident fishing without one. However, I am starting to do more inshore fishing in the creeks of the Pamlico, Pungo, and Bay River. In the warmer months I am mainly fishing the shorelines and not go out in the deeper water. Somebody convince me why I need a fishfinder. Is it like air conditioning, DVR, and high speed internet? One of those thing you don't appreciate until you have had it? Does it really help locate fish in these areas?
