i may have posted this in the wrong area....sorry if i did. my question is can i link my 798ci hd si to my new 998c hd si to use the same transducer. i only want the 798 for lake maps and speed at the console and already have a high speed ducer added on via y cable for it, works great. i want to put the 998 at the console also for side image only. can i use the same ducer or do i need to install the new 1 that came with the 998, and if i need to install the new 1, how far does it need to be away from the 798 transducer. if this has already been answered some where i appologize, i searched the posts but found nothing on this. thanks for any help
