Garmin GPSMAP 8000 Manuale Utente

Before you can set a fuel level alarm, a compatible fuel flow 

sensor must be connected to the NMEA 2000 network.
You can set an alarm to sound when the total amount of 

remaining onboard fuel reaches the level you specify.

Select Settings > Alarms > Fuel > Fuel Alarm > On.

Enter the remaining amount of fuel that triggers the alarm.

Before you can set weather alarms, you must have a 

compatible chartplotter connected to a weather device, such as 

a GXM™ device, and have a valid weather subscription.

Select Settings > Alarms > Weather.

Turn on alarms for specific weather events.

NOTE: Some settings and options require additional charts or 

hardware.
Select Settings > My Vessel.
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 (

Temperature Offset: Compensates for the water temperature 

reading from a NMEA 0183 water-temperature sensor or a 

Calibrate Water Speed: Calibrates the speed-sensing 

transducer or sensor (xx).

Fuel Capacity: Sets the combined fuel capacity of all the fuel 

tanks on your vessel (xx).

Vessel Type: Enables some chartplotter features based on the 

boat type.

You can enter a keel offset to compensate 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. Enter a positive number to offset for a keel. You can 

enter a negative number to compensate for a large vessel that 

may draw several feet of water.

Complete an action, based on the location of the transducer:
• If the transducer is installed at the water line 

À

, measure 

the distance from the transducer location to the keel of the 

boat. Enter this value in steps 3 and 4 as a positive 

number.

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

Á

, 

measure the distance from the transducer to the water 

line. Enter this value in steps 3 and 4 as a negative 

number.

Select Settings > My Vessel > Keel Offset.

Select   or   based on the location of the transducer.

Enter the distance measured in step 1.

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 > Temperature Offset.

Enter the temperature offset calculated in step 3.

If you have a speed-sensing transducer connected to the 

chartplotter, you can calibrate that speed-sensing device to 

improve the accuracy of water-speed data displayed by the 

chartplotter.

Select Settings > My Vessel > Calibrate Water Speed.

Follow the on-screen instructions.
If the boat is not moving fast enough or the speed sensor is 

not registering a speed, a message appears.

Select OK, and safely increase the boat speed.

If the message appears again, stop the boat, and ensure the 

speed-sensor wheel is not stuck.

If the wheel turns freely, check the cable connections.

If you continue to get the message, contact Garmin product 

support.

When your compatible chartplotter is connected to an AIS 

device or VHF radio, you can set up how other vessels are 

displayed on the chartplotter.
