Mille Lacs Lake Walleye Whiffer Partner by King Tutts Mapping

The Walleye Whiffer Partner is meant to be used with the Mille Lacs Walleye Whiffer II map. The latitude/longitude grid on the Whiffer map is in one minute intervals. By overlaying the Partner on the map coordinates can be determined to the hundreths which can then be entered into the GPS unit. The Partner also includes a compass for headings and a mile scale for distances.
