GPS Data Storage
Whenever your SC-1 is turned on and has a GPS solution (i.e. when it is showing you speed, heading or
distance-to-line information) it records GPS trackpoints every 2 seconds. Each trackpoint contains the
following information:
• Latitude
• Longitude
• Heading
• Speed
• Time
The SC-1 has room for 20 hours worth of GPS data. When the SC1's memory becomes full, the oldest
data on the device are automatically deleted to free up space for new ones. At any point in time, the
SC-1 will contain a record of your last several days of sailing.
