Garmin 5008 Manuale Utente

Configuring the Chartplotter

Safe Height—set the minimum height (chart height datum) of a bridge that your boat can safely 

travel under.
Shoreline Distance—set how close you want to travel near the shore: Nearest, Near, Normal, 

Far, or Farthest. This is used by the automatic guidance calculation to determine how close 

to the shoreline you want the automatic-guidance line to be. Changing this while navigating an 

automatic-guidance line will recalculate the path.

Keel Offset—offset 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. Enter a negative number to offset for a large vessel that may draw several feet of water.

1.  From the Home screen, select 

 >

.

2.  Use the 

 (GPSMAP 4000 series) or the onscreen keyboard (GPSMAP 5000 series) to 

specify the offset.

3.  Select 

 to accept the number.

  NOtE: Select 

 to cancel your changes and return to the My Boat screen.

temp Offset—set the temperature offset for the temperature sensor of your transducer.
Calibrate Water Speed—use this menu to calibrate a speed-sensing device. Follow the on-screen 

directions for calibration. If you do not have a speed-sensing device, this menu does not appear.

  NOtE: If the boat is not moving fast enough or the speed sensor is not registering a speed, a “Speed 

Too Low” message appears. Select 

 and safely increase boat speed. If you get the message again, 

stop the boat and make sure 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.

Fuel Capacity—enter the total fuel capacity of your boat.

To configure settings for boats other than your own, from the Home screen, select 

 > 

.

AIS—turn AIS (Automatic Identification System) on or off. AIS alerts you to area traffic by 

providing boat IDs, position, course, and speed for boats that are within range and equipped with a 

transponder.
DSC—turn DSC (Digital Selective Calling) on or off.

  NOtE: To configure AIS or DSC information for other boats, your unit must be connected to an 

external AIS or DSC device. 

Collision Alarm (AIS and MARPA only)—turn a safe zone around your boat on or off. This is used 

for collision avoidance, and can be customized.

From the Home screen, select 

 > 

> 

.

Range—change the measured radius of the safe-zone ring to a specified distance from 500 ft. 

to 2.0 nm (or from 150 m to 3.0 km, or from 500 ft. to 2.0 mi).
Time to (Safe Zone)—sounds an alarm if AIS or MARPA determines that a target will intersect 

the Safe Zone within the defined time interval (ranging from 1 to 24 minutes).
