And yet another HB question???

I just got my interference kit in today and boy was I amazed. I told them I was getting bad interferance when I operated my trolling motor. They sent me a box full of wierd looking gadgets and even a shielded transduser for the back(I have 797 on the console). My question is, should I replace everything they sent me including the rear transducer or should I start by trying the donut things first. That big "trolling motor choke" is going to be hard to hide and if I don't need it I would rather not full with it. I have not been getting any interference at the console but will this new transducer help anything or show a better picture? I have just downloaded the new software and have not yet tried the 787 to see if my problems where solved with the new software. Thanks for any input.

I would install everything we sent to you in the interfernce kit. This kit is designed to help get rid of the interference in your boat.
