I am looking to purchase a 998c. I currently use a 798c at the console and have an in-hull for high speed and SI transducer on the jackplate. They are connected using the y-cable.
Regardless of speed, I understand that the y-cable will always use the in-hull for 2d sonar. I have tried everything and unfortunately get very inconsistent readings from the in-hull transducer. Because the readings are inconsistent with the in-hull transducer, I want to use the SI Transducer for low speed (less than 5 mph) as I am sure it give me better readings as the sonar signal is not through the hull. Before I started using the y-cable, I used the TS2 W Switch. Generally, will the y-cable give me better readings than the switch or is the y-cable just more convenient??? I do not mind using the switch but is it more difficult (wear and tear) on the unit than the y-cable?
Thanks

The TS-2 has been changed to the TS-3. Same operation different mount.
The switch allows you to switch between two transducers.
The y-cable allows two transducers to be connected to a single unit.
Other than manual operation of the switch you get the same results..

The y-cable is more convenient, less costly and has hands-free operation.
I would look at the installation of that inside-the-hull transducer to start with though. One important step that many skip is the testing of the transducer in the location before it is epoxied in place. I know a lot of “professionals” who skip this step and theor Customers end up contacting Humminbird because their Humminbird unit does not work at high boat speeds. Testing before epoxying is the only way to be sure that you have the transducer located in the correct location. I know this because I have installed more than one or two inside-the-hull transducers that did not work well… ::)
