I'm going to buy the 788ci HD DI  unit. 
Plus I am going to buy a transducer saver by 
www.transducershieldandsaver.comThe company says that model ssc-3 will fit the XNT-9-20 transducer.
What I like to know what dos the new 788ci HD DI transducer look like ?  
Is it the same as the XNT-9-SI 180T transducer ?
Huminbird says the 788ci hd di uses the XNT-9 Di T  
I like to know what transducer comes close or the same size as the XNT-9-DI T transducer.
Thank you very much.
