I have a C-Map MAX electronic chart for the USA West Coast and Hawaii (#M-NA-MO24) in SD Format. The SD card is has never been used and is in the original packaging. I am asking $80.00 (including domestic shipping) for the card.
C-MAP MAX - M-NA-MO24 USA West Coast & Hawaii - SD
The date on the SD card shows September 5, 1914. I purchased it in January of 1915 as we were preparing to bring our Trawler back to California from Mexico.
