can easily switch ranges by pressing the

 keys. 

Radar Echo Expansion 
The Radar Echo Expansion feature will make weak signals more visible 
on the display by lengthening radar echoes.

, highlight 

and

press 

 to turn it on (check) or turn it off (uncheck). Press

clear the radar menu. Radar Echo Expansion is good for seeing weak 

echo returns — like birds — at a distance. 
Remember, when Echo Expansion is on, all signals on the display will 
be enlarged, including clutter. 
Echo Trail Interval 
The Echo Trail Interval feature displays an on-screen history (trail) of 

the movements of all radar targets. 

1. From the radar page, press 

, select 

 and press 

, which will launch the Echo Trail Interval menu. 

2. The Echo Trail Interval menu will display a series of intervals with 
options ranging from Continuous to Off. Use 

↑  ↓ to highlight the de-

sired interval and press 

. Press 

 to close the menu. 

This feature is best used in open water or when your vessel is sta-

tionary and you are tracking a moving target. If Echo Trail Interval 
is on and your vessel is moving, the display will be crowded with 

trails for every target, including stationary targets, like lighthouses 

and land.
