I have an old autohelm tridata which I assume is the same as the raymarine i40 and I need to upgrade. Will the new transducers in the i50, i60 be the same size as the old tridata? I have no info on the old units but they are separate speed and depth and removable with plugs and a flapper (?) to restrict water inflow. I also have a repeater that's not really neccesary. Not anywhere near the boat to measure.
