bought the transducer last year and i am redoing my electronics and don't need this anymore, ducer is in great shape with no scratches and it has built in temp sensor, $40 tyd

also have a 20' humminbird tansducer extension cable $45 tyd works with a wide range of ducers including si

and lastly i have a US2 humminbird adapter, $17 tyd

will cut a package deal if you buy two and even better deal if you get all three, saves me shipping and time and i will pass that back to you,
pm for any info not covered and i can text pics if need be.
