I just got a new to me 898C SI and it works but was wondering if the XHS 9 HDSI 180T tranducer is any upgrade to the clarity of the unit. I was going to buy a transom mount TD anyway and figured the extra 50 bucks would be worth it. Also plan on upgrading as time goes on and that seems to be what the Helix uses. From what I've read it helps a little bit. My little 597HD DI is much sharper.
If you have one collecting dust let me know as I'll be heading to Cabelas in a day or two otherwise. HAHA
thanks as always
