Thread: Garmin rino marks lost

In fact most marine plotters once you delete the marks they are gone (if they are saved on the plotters internal memory.
If you can save them to and SD card then if deleted from there you can usually un-delete them via a pc and recovery software
MOF (Ministry of Fisheries) also have some really neat ways to recover data but the outcome for the units owner is often far from happy in these cases

Not much help to ya @stretch ,
