Hmmm. I dont have that (yet). Its the standard connector that was on the boat. This leads to another question. I have a Lowrance 520 dash unit. The 520 is being repaired/replaced right now and I was wondering if the HDS5 will work with the Lowrance 520 hull transducer? Its probably the same connector – needs adapter. Thanks and Kudos.
