Each readout position can either be empty or contain one of the items from the following table:
Bearing Bearing is the direction to a destination waypoint measured in degrees from North (i.e. 321°, where 000° is
North, 090° East, 180° is South, 270° is West).
CMG/SMG Course Made Good/Speed Made Good. Course Made Good is the angle between the starting point on a route and
the current position of the boat. The goal is to have CMG and Track equal to the same number. See the Course
Made Good illustration. Speed Made Good is the distance from the starting waypoint on the route divided by the
time elapsed since starting navigation on the route.
Course Course is the current direction the boat is traveling measured in degrees from North (i.e. 321°, where 000° is
North, 090° East, 180° is South, 270° is West). When the Course Over Ground is equal to Bearing, the boat is
said to be "On Course" and will arrive at the destination in the most efficient manner. See the Glossary for more
information.
Depth Displays the depth of the water.
Off Suppresses the readout so that no data shows in that position.
Position Position is the current location (latitude, longitude) determined by GPS.
Speed Speed is the measurement of the boat's progress across a given distance; the speed measurement provided by
GPS; accurate destination times can be derived from this measurement. See the Glossary for more information.
TRK/CMG Track/Course Made Good. The Track Line is the desired line of travel between two waypoints, and represents the most
efficient path between the two points because it is a straight line. The TRK is measured in degrees. See above for an
explanation of Course Made Good.
TTG Time to Go is the estimated time required to reach the next waypoint on the route. TTG is calculated using the SOG
(Speed Over Ground) and DTG.
Temp The current detected water temperature.
Aux. Temp The current detected water temperature from an optional-purchase Temperature Probe or Temp/Speed accessory.
Time The current time.
Time + Date The current time and date.
Timer Displays the timer countdown. See Alarms Menu Tab: Timer Setup.
Triplog Displays the triplog, which measures the elapsed time since last reset, the distance traveled since last reset, and
average speed during timed interval.
VMG Velocity Made Good. Velocity Made Good is the speed of travel relative to the next waypoint on the route. The
goal is for VMG to equal Speed.
Voltage Power supplied to the control head.
WPTend/ETA/DTG Waypoint End/Estimated Time of Arrival/Distance to Go. Waypoint End is the last waypoint on the route.
Estimated Time of Arrival is the estimated time of arrival to the last waypoint on the route. Distance To Go is the
distance between the current position of the boat and the last waypoint on the route.
WPTend/TTG/DTG Waypoint End/Time To Go/Distance to Go. Waypoint End is the last waypoint on the route. Time To Go is the
estimated time required to reach the last waypoint on the route. TTG is calculated using the SOG and DTG. Distance
To Go is the distance between the current position of the boat and the last waypoint on the route.
WPTnext/ETA/DTG Waypoint Next/Estimated Time of Arrival/Distance to Go. Waypoint Next is the next waypoint on the route.
Estimated Time of Arrival is the estimated time of arrival to the next waypoint on the route. Distance To Go is the
distance between the current position of the boat and the next waypoint on the route.
