Can a Single Radar Networked to Multiple Chartplotters Provide Different Ranges

Compatible Garmin chartplotters, connected to a Garmin radar, can display radar returns for areas from 1/8 of a mile up to a maximum of 72 nautical miles.* The user applies settings from the chartplotter to select the range of radar returns to show on the chartplotter screen.
If multiple chartplotters are connected to the radar simultaneously, each screen will show the same radar returns at the same range. Having two connected chartplotters display a different range from one radar is impossible. Changing the range on one screen will also cause all other connected screens to change range.

The Dual Range option shows a split-screen, with each side of the split-screen having a user-adjustable range. The screen's left side can show a range of three nautical miles or smaller, and the right side of the screen can show a range of 3 nautical miles or larger. All compatible chartplotters on the network will show the same dual ranges as the other network devices.

*The maximum radar range is dependent on which model of radar is being used. Refer to the Owner's Manual or Installation Instructions for your radar for your device's maximum distance capabilities.
