LEARNING TO READ THE DISPLAY 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
With Zoom activated the two 
objects close to the bottom on 0-60 
ft scale can now be seen as fish off 
the bottom. 

 
Thermocline is a temperature 
change at a certain depth in the 
water. In some conditions the 
sonar waves will actually reflect 
or bounce off this temperature 
change and therefore it will be 
displayed on the LCR as shown 
above. To see the thermocline, 
you will need to go to the 
manual mode and increase the 
sensitivity setting. 
 
One of the best ways to learn to 
use your LCR is to go over 
familiar locations. If you know 
what's under the water and can 
see it displayed on the LCR 
then you’re on your way toward 
gaining the experience you 
need.
