Safe Depth : Sets the appearance of a safe depth for the Mariner’s Eye 3D chart view. NOTE: This setting affects only the appearance of hazard colors for the Mariner’s Eye 3D chart view. It does not affect the safe water depth Auto Guidance setting or the sonar shallow water alarm setting. Range Rings : Shows and configures the appearance of range rings, which help you to visualize distances in some chart views. Lane Width : Specifies the width of the navigation lane, which is the magenta line in some chart views that indicates the course to your destination. Fish Eye 3D Settings NOTE: This feature is available with premium charts, in some areas. From the Fish Eye 3D chart view, select MENU.
View : Sets the perspective of the 3D chart view. Tracks : Shows tracks. Sonar Cone : Shows a cone that indicates the area covered by the transducer. Fish Symbols : Shows suspended targets. Navigation with a Chartplotter Setting the Heading and Course Over Ground Lines You can show the heading line and the course over ground (COG) line on the chart. COG is your direction of movement. Heading is the direction the bow of the boat is pointed, when a heading sensor is connected.
1 From a chart view, select MENU > Chart Setup > Chart CAUTION If your vessel has an autopilot system, a dedicated autopilot control display must be installed at each steering helm in order to disable the autopilot system. The Auto Guidance feature is based on electronic chart information. That data does not ensure obstacle and bottom clearance. Carefully compare the course to all visual sightings, and avoid any land, shallow water, or other obstacles that may be in your path. When using Go To, a direct course and a corrected course may pass over land or shallow water. Use visual sightings, and steer to avoid land, shallow water, and other dangerous objects. Appearance > Heading Line .
2 If necessary, select Source , and select an option: To automatically use the source available, select Auto . To use the GPS antenna heading for COG, select GPS Heading (COG) . To use data from a connected heading sensor, select Heading . To use data from both a connected heading sensor and the GPS antenna, select COG and Heading . This displays both the heading line and the COG line on the chart. 3 Select Display , and select an option: NOTE: Some chart views are available with premium charts, in some areas. To navigate, you must choose a destination, set a course or create a route, and follow the course or route.
You can follow the course or the route on the Navigation chart, Fishing chart, Perspective 3D chart view, or Mariner’s Eye 3D chart view. You can set and follow a course to a destination using one of three methods: Go To, Route To, or Guide To. Go To : Takes you directly to the destination. This is the standard option for navigating to a destination. The chartplotter creates a straight-line course or navigation line to the destination. The path may run over land and other obstacles. Route To : Creates a route from your location to a destination, allowing you to add turns along the way.
This option provides a straight-line course to the destination, but allows you to add turns into the route to avoid land and other obstacles. Guide To : Uses the specified information about your vessel and chart data to determine the best path to your destination. This option is available only when using a compatible premium chart in a compatible chartplotter. It provides a turn-by-turn navigation path to the destination, avoiding land and other obstacles ( Auto Guidance , page 11 ). NOTE: Auto Guidance is available with premium charts, in some areas. Select Distance > Distance , and enter the length of the line shown on the chart.
Select Time > Time , and enter the time used to calculate the distance your boat will travel in the specified time at your present speed. Other Vessels Settings on the Charts and Chart Views NOTE: These options require connected accessories, such as an AIS receiver or VHF radio. From a chart or 3D chart view, select MENU > Other Vessels . AIS List : Shows the AIS list ( Viewing a List of AIS Threats , page 5 ). DSC List : Shows the DSC list ( DSC List , page 17 ). AIS Display Setup : See AIS Display Settings , page 7 . DSC Trails : Shows the tracks of DSC vessels, and selects the length of the track that appears using a trail. AIS Alarm :
Sets the safe-zone collision alarm ( Setting the Safe- Zone Collision Alarm , page 5 ). AIS Display Settings NOTE: AIS requires the use of an external AIS device and active transponder signals from other vessels. From a chart or 3D chart view, select MENU > Other Vessels > AIS Display Setup . AIS Display Range : Indicates the distance from your location within which AIS vessels appear. Details : Shows details about AIS-activated vessels. Projected Heading : Sets the projected heading time for AIS- activated vessels. Trails : Shows the tracks of AIS vessels, and select the length of the track that appears using a trail.
Basic Navigation Questions Navigation with a Chartplotter 7 Question Answer How do I make the chartplotter point me in the direction in which I want to go (bearing)? Navigate using Go To. See Setting and Following a Direct Course Using Go To, page 8. How do I make the device guide me along a straight line (minimizing cross track) to a location using the shortest distance from the present location? Build a single-leg route and navigate it using Route To. See Creating and Navigating a Route from Your Present Location, page 9.
