Bought a new 598ci with free di and cant seem to find how to use down imaging.Replaced the HB 717 and using the hockey style puck from that 717.Should I be using the tranducer that came with the new unit.I noticed on the 717 prong it has 4 and on the 598 it has 5,maybe that 5th one is down image.What do you guys think?
