I have a 898 and 858 on my 18ft aluminum boat and I want to just switch the head units over to my tuffy. Which transducer or transducers do I buy, because mine are not the HD units. Are they the same transducer as the HD units?.. Could I get away with only running one transducer for both? I heard guys using some sort of Y cable.. Thanks Guys.. Im hoping I get this installation right on this boat so I can get as good of pictures as you guys post your units are getting.
