Thread: Humminbird Base Map

Does anyone use the Humminbird Base Maps for Grenad/Enid/Sardis? If so, does it show the entire lake bed with contours on all 3 lakes?
I know the Lakemaster Southeast chip has closer contours just wasn’t sure about the Base Map
thanks

The HB basemap is built into the unit.

Turn the unit on and page to the map screen then cursor over to the area you would like to check.

Good Luck
