I just purchased a used 2011 Tracker Pro Team 175 TXW. I'm considering upgrading the two Lowrance fish-finders to new units. I'm looking at the Garmin echoMAP CHIRP 53 CV. I like the map features of this unit. I'm thinking about putting one at the console and one forward by the trolling motor. I understand that both transducers will need to be mounted on the transom because of the side view feature. I'm fairly tech savvy, but I'll admit to being in unfamiliar waters here (pun intended). Any advice, opinions or possible pitfalls in doing this would be appreciated.
