The table below displays the basic data box options that are shown in the Standard data bar and the Navigation data bar, as well as the additional data box options for vessel, wind, and engine. The data box options are determined by the installed equipment and the selected sources on the Humminbird or NMEA 2000 network.
Label | Name | Description | Data Type |
Depth (#) | Depth | The depth of the water from the transducer or digital depth sensor to the bottom. This measurement includes the depth offset setting. | Depth |
DBT | Depth Below Transducer | The depth of the water below the transducer. This measurement does not include the depth offset setting. | Depth |
Eng Temp (#) | Engine Temperature | The engine temperature from the engine source. | Engine |
Eng Volt (1) | Engine Voltage | The power supplied to the engine source. | Engine |
RPM | Revolutions Per Minute | The number of engine revolutions per minute. | Engine |
Heat Index | Heat Index | The perceived temperature derived from air temperature and relative humidity. | Environment |
Temp (#) | Water Temperature | The detected water temperature. | Environment |
Temp (Air) | Air Temperature | The detected air temperature. | Environment |
Fuel (#) | Fuel Level | The fuel level of the fuel source. | Fuel |
CTS | Course to Steer | The heading that must be maintained in order to reach the planned destination. | Navigation |
Dest Wpt ID | Next Waypoint | The next point (waypoint, route point, Man Overboard point, etc.) that the vessel is navigating towards in a route or other navigation mode. | Navigation |
Next Turn | Next Turn | The course of the next route leg with respect to the current heading. | Navigation |
TTG | Time to Go | 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). | Navigation |
Brg | Bearing | The compass direction from the vessel position to the next waypoint or route point. | Navigation |
Brg (End) | Bearing (To End) | The compass direction from the vessel position to the final point in a route. | Navigation |
Course | Course | The intended direction of travel measured between the start point and end point. | Navigation |
CMG | Course Made Good | The bearing from your starting position to the present vessel position. The goal is to have CMG and Track equal to the same number. | Navigation |
DMG | Distance Made Good | The straight line distance actually traveled between the start position to the current vessel position. | Navigation |
DTG | Distance to Go | The distance between the vessel position and the next waypoint or route point. | Navigation |
ETA | Estimated Time of Arrival | The estimated time of arrival to the next waypoint on the route. | Navigation |
XTE | Cross Track Error | The straight-line distance of the boat from the intended Track. XTE measures how far the boat is off course. | Navigation |
SMG | Speed Made Good | The distance from the starting waypoint on the route divided by the time elapsed since starting navigation on the route. | Speed |
SOG | Speed Over Ground | The measurement of the boat’s progress across a given distance and the speed measurement provided by GPS. SOG is optimal for navigation because accurate destination times can be derived from this measurement. | Speed |
STW | Speed Through Water | The measurement of the flow past the boat, which may vary depending on current speed and direction. | Speed |
VMG | Velocity Made Good | The speed of travel relative to the next waypoint on the route. | Speed |
COG | Course Over Ground | The current 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. | Vessel |
Hdg | Heading | The direction the boat is pointing, measured in degrees. Due to wind and waves, the boat is often traveling in a slightly different direction than its heading. See Course Over Ground (see COG). | Vessel |
Odo | Odometer | The distance traveled. | Vessel |
Pitch | Pitch | The rotation angle of the boat from front to back (bow to stern). | Vessel |
Position (#) | GPS | The latitude and longitude coordinates of the vessel position based on the GPS receiver installation location. | Vessel |
Roll | Roll | The rotation angle of the boat from side to side (port to starboard). | Vessel |
ROT | Rate of Turn | The rate at which the boat is turning, measured in degrees per second. | Vessel |
Alt | Altitude | The height measurement above sea level. | Vessel |
AWA | Apparent Wind Angle | The direction of wind relative to the bow of the vessel. | Wind |
AWS | Apparent Wind Speed | The speed of wind with respect to the speed of the vessel. | Wind |
TWA | True Wind Angle | The wind angle detected when the vessel is stationary. | Wind |
TWS | True Wind Speed | The wind speed detected when the vessel is stationary. | Wind |
