Actually it is true. On pagr 48 of the owner's manual, it clearly states "only one ballistics curve can be saved on the card"Actually this is not true. The Bino reads ONLY the file in the root directory of the SD card. You can have multiple files on the SD say in a separate directory. You do have to have a computer to move them around but...
I called Leica customer service to confirm this when I bought the bino last year.
