visibility, Galileo data can be used in combination with GPS

to provide more accurate position information.

Speed Filter: Averages the speed of your vessel over a short

period of time for smoother speed values.

Source: Allows you to select the preferred source for GPS data.

Viewing the Event Log

The event log shows a list of system events.

Log.

Viewing System Software Information

You can view the software version, the basemap version, all

supplemental map information (if applicable), the software

version for an optional Garmin radar (if applicable), and the unit

ID number. You may need this information to update the system

software or to purchase additional map data information.

hardware.

Keel Offset: Offsets the surface reading for the depth of a keel,

making it possible to measure depth from the bottom of the

keel instead of from the transducer location

tanks on your vessel

Vessel Type: Enables some chartplotter features based on the

boat type.

Fill Up All Tanks: Sets the tank levels to full

Setting the Keel Offset

You can enter a keel offset to compensate the water depth

reading for the transducer installation location. This allows you

to view the depth of the water below the keel or the true depth of

the water, depending on your needs.

If you want to know the water depth below the keel or the lowest

point of your boat and the transducer is installed at the water

line or anywhere above the end of the keel, measure the

distance from the transducer location to the keel of the boat.

If you want to know the true water depth and the transducer is

installed below the water line, measure the distance from the

bottom of the transducer up to the water line.

NOTE: This option is only available when you have valid depth

data.

Measure the distance:

• If the transducer is installed at the water line

anywhere above the end of the keel, measure the

distance from the transducer location to the keel of the

boat. Enter this value as a positive number.

• If the transducer is installed at the bottom of the keel

and you want to know the true depth of the water,

measure the distance from the transducer to the water

line. Enter this value in as a negative number.

Select Settings > My Vessel > Keel Offset.

Select

if the transducer is installed at the water line, or

select

if the transducer is installed at the bottom of the

keel.

Setting the Water Temperature Offset

Before you can set the water temperature offset, you must have

a NMEA 0183 water-temperature sensor or a temperature-

capable transducer to measure water temperature.

The temperature offset compensates for the temperature

reading from a temperature sensor.

Measure the water temperature using the temperature sensor

or temperature-capable transducer that is connected to the

chartplotter.

Measure the water temperature using a different temperature

sensor or a thermometer that is known to be accurate.

Subtract the water temperature measured in step 1 from the

water temperature measured in step 2.

This is the temperature offset. Enter this value in step 5 as a

positive number if the sensor connected to the chartplotter

measures the water temperature as being colder than it

actually is. Enter this value in step 5 as a negative number if

the sensor connected to the chartplotter measures the water

temperature as being warmer than it actually is.

Select Settings > My Vessel > Temp. Offset.

Enter the temperature offset calculated in step 3.
