I have a 597ci HD di with transom mount XT 9 NT transducer, and just ordered a 998c si that should arrive this week. I will mount the 597 at the stern (I do a lot of controlled drift fishing on the Mississippi) and the 998 at the console. I understand that with a Y cable I can switch the 998 between the side imaging transducer and the XT 9 NT for 2D/keeping track of bottom when running at speed.
The 597 does not network, of course. Can anyone think of a combination of cables and switches that would allow me to switch between transducers for the 998 as described above, AND use the same XT 9 NT transducer on the 597 - when looking at the 597 the 998 does not need to access the NT of course.
Thanks in advance for any advice.
