Found in a garage at an estate sale, this is a new in original sealed box Humminbird 16 degree high speed transducer, model XHS-6-16. As shown, the box has some shelf wear and writing on top but the seal has never been broken. The chart in the last photo shows the several models of fish finders that this transducer fits. I do not know the year this transducer was issued; perhaps early 2000s? Please see the photos and message with questions.
