How to add bookmarks
While diving, keep the lower button pressed to add a bookmark (timestamp) to the active log for later reference.

Bookmarks save the following information: time stamp, depth, temperature, and pressure if tank pod is used. Data can be seen in Suunto app after the dive.
NOTE:
        
                                    In compass view, long pressing the lower button locks the bearing.
