Selecting a Chart Type for the Radar Overlay You can indicate whether the Navigation chart or the Fishing chart appears under the Radar Overlay. Note: The Fishing chart is available with a preprogrammed BlueChart g2 Vision data card. 1. From the Home screen, select Radar > Radar overlay > Menu > Setup > Chart Setup. 2. Complete an action: • Select Chart type > Navigation. • Select Chart type > Fishing. Optimizing the Radar Display You can optimize the radar display for Cruising mode, Harbor mode, Offshore mode, or Sentry mode individually, and for each screen in Dual Range mode. 1. From the Home screen, select Radar. 2. Select Cruising, Harbor, offshore, Dual Range, or Sentry. 3. Select a radar range (page 85). 4. Restore the default value of the gain setting (page 86). 5. Restore the default value of the sea clutter setting (page 88). 6. Restore the default value of the rain clutter setting (page 89). 7. Restore the default value of the FTC setting (page 89). 8. Restore the default value of the crosstalk setting (page 91). 9. Adjust the gain setting manually (page 86). 10.Adjust the sea clutter setting manually (page 88). 11.Adjust the rain clutter and FTC settings manually (page 90). GPSMAP® 6000/7000 Series Owner’s Manual Radar About the Range of Radar Signals The range of the radar signal indicates the length of the pulsed signal transmitted and received by the radar. As the range increases, the radar transmits longer pulses in order to reach distant targets. Closer targets, especially rain and waves, also reflect the longer pulses, which can add noise to the Radar screen. Viewing information about longer-range targets can also decrease the amount of space available on the Radar screen for viewing information about shorter-range targets, unless you are using Dual Range mode (page 75). Tips for Selecting a Radar Range • Determine what information you need to see on the radar display. For example, do you need information about nearby weather conditions or targets and traffic, or are you more concerned about distant weather conditions? • Assess the environmental conditions in which the radar is being used. Especially in inclement weather, longer-range radar signals can increase the clutter on the Radar screen and make it more difficult to view information about shorter-range targets. In rain, shorter-range radar signals can enable you to view information about nearby objects more effectively, if the Rain Clutter and FTC settings are configured optimally. • Select the shortest effective range, given your reason for using radar and the current environmental conditions. Selecting a Radar Range See “Adjusting the Zoom Scale on the Radar Screen” (page 72). About Gain and Clutter The gain controls the sensitivity of the radar receiver. The default setting for the gain, Auto, sets the gain automatically one time, based on average conditions, the range of the radar signal, and the selected radar mode. The chartplotter does not readjust the gain automatically in response to changing conditions. To optimize the radar appearance for specific conditions, manually adjust the gain (page 86). Clutter is interference caused by the unwanted reflection of radar signals off of unimportant targets. Common sources of clutter include precipitation, sea waves, and nearby radar sources. Settings Configurations and Radar Type When using a GMR 20, 21, 40, 41, 18, 18 HD, 24, 24 HD, 404, or 406, all gain and clutter settings configured for use in one radar mode are applied to every other radar mode and to the Radar Overlay. When using a GMR 604 xHD, 606 xHD, 1204 xHD, or 1206 xHD radar, gain and clutter settings configured for use in one radar mode may or may not be applied to other radar modes, according to this table.

For example, if the gain for the Harbor mode is set to 50%, the gain for the Radar Overlay is set to 50% automatically. Later, if the gain for the Offshore mode is set to 40%, the gain for the Radar Overlay is set to 40% automatically.
