I believe the transducer that comes with the helix 10 si is the
XHS 9 HDSI 180T. If I am going to use the helix 10 si on the trolling motor, is there a different transducer I should be using to reduce the possibility of rf interference ?

I thought I "read" there was a transducer that had additional shielding and was possibly a longer unit that should or could be used on the trolling motor? I searched through some threads but could not locate it...
