I’ll be at the Potomac for the first time for a week mid August.
None of my chips seem to work on the Potomac.
i have both Lowrance and Humminbird but prefer to use my G3N bird for mapping.
What is the best chip to get for the Potomac? Will also be on Champlain and St.Lowrance but my old Navionics chips have OK detail on those lakes.
Thanks
