Connecting Two Transducers to the Garmin GSD 25

The GSD 25 has two transducer ports; an 8-pin port and a 12-pin port. In cases where you are upgrading from older hardware to the GSD 25, you may encounter a situation where you have an existing transducer you wish to use in addition to a new ClearVü/SideVü transducer. You can do this with the GSD 25, but it may create a redundant situation. Garmin produces many transducers that will allow you to utilize all the capabilities the GSD 25 with one transducer.
