Summary: I bought a new Lund 1775 Impact boat equipped with a Minn Kota Terrova Ipilot 80(US2 transducer), Humminbird 385ci DI and 788ci DI HD sonar units and have experienced display and performance issues with the equipment configuration. I have also incurred considerable expenses to fix the issues. I had the Lund dealer install the trolling motor and sonar units The 385 unit connected to the trolling motor US2 transducer didn't display an accurate depth reading.
Summary: do i need a bigger screen? do i need a 200/50 dept finder? should i buy a more expensive brand. will the learning curve be to steep? the answer is no! i love this thing! it fits right on my dash, dosn't block my view, and works great! what more do you need.
