5 Selectable Readouts Used by All Non-Instrument Views; Navigation Mode
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.

 

 

COG

Course Over Ground. Course Over Ground 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.

 

 

Off

Suppresses the readout so that no data shows in that position.

 

 

Position

Position is the current location (latitude, longitude) determined by GPS.

 

 

SOG

Speed Over Ground. Speed Over Ground 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. Time To Go is the estimated time required to reach the destination waypoint. TTG is calculated using

 

the SOG 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.

 

 

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.

Water Speed

The current speed of the water as it flows past the boat.

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.

WPTnext/TTG/DTG Waypoint Next/Time To Go/Distance to Go. Waypoint Next is the next waypoint on the route. Time To Go is the estimated time required to reach the next 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 next waypoint on the route.

Waypoint/TTG

Waypoint/Time To Go. Waypoint/Time To Go for the next waypoint on the route.

XTE

Cross Track Error is the straight-line distance of the boat from the intended Track. XTE measures how far the boat

 

is off course, and also triggers the Off Course Alarm.
