Went today with my Elite 7 HDI. I am not sure the down scan transducer is working properly. At times it would not show any bottom regardless of the speed. I did a factory reset.even set it up with a copy of the settings received from CDC. Some times the bottom could hardly be seen. Some times you would think it was working and then the bottom would disapear. This was a unit ordered to replace the transducer that I damaged during installation. Do they have a warrenty? Any ideas or suggestions would be helpful. Is the only fix ....another transducer?........thanks....crappir1133
