Hey guys, I am new to the board, and I have a question. What is the best Fish finder for the money? I am looking for something to put at the bow on the trolling motor. I am looking at a Garmin ECHOMAP Plus 93sv with GT52 Transducer Fish Finder/Chartplotter Combo that I have found on clearance. However, I am open to anything in the Sub $700 range. Thanks in advance for your input!!!
