Dwaw,
Sometimes you have to check more than a few feet down the cable (from the connector end) for the label and even than it may be printed so lightly that it is hard to make out (we are in the process of changing it now so they will start being more readable in the future). Regardless if that is the transducer that came with your 798 unit than it should be the correct one and you should get Side Imaging and Down Imaging sonar from it.
