Good day.
I asked HB support about installing a HB transducer in my boat they gave me a part number for the plastic transducer xth 9 20p. On the website it says its a "kayak transducer". Anyway I already have a bronze thru hull that the P.O. had a sitex sounder installed and was wondering if the the xth 9 20 bronze would work instead. They said to get the y adaptor. SO would the 999 know to switch between transducers automatically or would I have to change them when I swap between SI and DI etc. I would anticipate having better bottom lock and readings on returns at speed because it will be mounted in an area that does not have any "disturbance". Thank you for your input. Looking to put an order in today. Cheers.
