Navionics Cartography

Navionics manufactures some of the most popular electronic charts going. Navionics' charts come in five formats: Gold, Platinum, HotMaps Premium, HotMaps Platinum, and the new Navionics +. Most units take the MSD version which comes in an SD format with an MSD card inside which will accommodate most units taking MSD and SD version charts. Older Raymarine units will take CF versions.
