I currently have a 998 at the console and a 587 at the bow. I would like to replace my 587 with a helix 9. The only down side I see is the 9 comes with the compact si transducer without 800htz instead of the hdsi transducer. My question is if I did the transducer exchange program and got the hdsi transducer would it support the 800htz beam? If it won't I may just pick up one of the hot deals on a 999 for $900. I still haven't got to see the new helix in person yet, bass pro or cabelas in my area don't have them yet.
