Adding GPS coordinates to a HB 999
How do I do this without visiting each location and marking it? I have a list of GPS coordinates on the lake I fish and would like to add them to my 999 unit. But I'm lazy and would like to do it without visiting each location if it is possible.
I've read the HB literature and manuals and find plenty of information on how to import and export data from one machine to another. But I have not found anything about how to add GPS coordinates manually without visiting and marking the locations.
I can add them to a card but I don't know the HB required format for this information.
I appreciate any advice, tips or instructions on how to do this.
