sonar log (.sl2) files. Saved mode is used to view a map of the underwater
environment that can be reviewed and examined either on or off of the
water. It can be used when revisiting an area that has already been scanned
in order to assist the user in positioning the vessel or locating specific points
of interest.
NOTE: If there is more than one StructureMap of the same area on
the same SD card, the maps will overlap on your screen. If you want
to have more than one map of the same area, you should put the
maps on separate SD cards.
