Just purchased a 798ci SI and when making appointment for install I was told that the transducer will not give any readout images at cruising speed. If I wanted any kind of image at cruise I would need to install another thru hull transducer and Y cable. Planning on transom mount but may change to trolling motor.
I don't expect SI at cruise but would like something, at least what I got with the 400tx units.
Does anyone have experence with this issue ?
