Description
The direction to a destination waypoint measured in degrees from north.
The direction the boat is traveling measured in degrees from North.
When the COG is equal to Bearing, the boat is said to be on course and
will arrive at the destination in the most efficient manner.
The depth of the water from the transducer or digital depth sensor
to the bottom. This measurement includes the depth offset setting.
If the depth number is flashing, it means the unit is having trouble
locating the bottom. This usually happens if the water is too deep, the
transducer is out of the water, the boat is moving too fast, etc.
The distance between the boat position and the next waypoint on the
route.
The estimated time of arrival to the next waypoint on the route.
The latitude and longitude coordinates of the boat position based on the
GPS receiver installation location.
Speed is the measurement of the boat's progress across a given
distance based on the speed measurement provided by the GPS.
The detected water temperature by the transducer's internal
temperature probe or an accessory temperature sensor.
The current time.
The current time and date.
The digital readout for the timer set in the Alarms tab (see Manage your
Control Head: Start the Timer).
The elapsed time since the triplog was last reset, the distance traveled
since last reset, and the average speed during timed interval. To reset the
triplog, see Getting Started: Reset the Triplog.
The estimated time required to reach the next waypoint on the route. TTG
is calculated using the SOG (Speed Over Ground) and DTG (Distance to Go).
Power supplied to the control head.
The straight-line distance of the boat from the intended route. XTE
measures how far the boat is off course.
