I was hoping a few folks could chime in on a question I have. I currently have a Garmin 3210 with Digital Sonar on a transom mount transducer. The Grady I have used to have a Sitex 106 with thruhull tranducer. The transducer cord and transducer are still installed. I don't think I can get what is worth and was wondering if I could run both of these sonars simultaneously for extra coverage. I know the Sitex is a little older but have heard they preform well. SOmetimes I wonder about what I am actually seeing on the Garmin. Thanks.
