I'd like to upgrade to the 1871 from the 1870. I'm curious if I'd need to swap out my transducer. I'd rather not if I can avoid it. My transducer is a B744V Bronze thru hull (Part# 152-A26043). I didn't put the thru hull in and this is all the info I have on same after going through the records for the boat. I searched it, but can't find definitively what I have.
