6.10.3 Color Rejection (Reducing the image color) 

Acoustic noise caused by the bubbles or other oceanic factors may be displayed on the screen in a 

weaker color like white, pale green, etc. Certain types of fish school such as squid and baby anchovy 

may also be displayed in similar colors. In such a case, reduce the number of colors on the color palette 

to better discern the school of fish and noise. 

Initial setting: 14/14 (all colors used) 

Setting range: 1/14 to 1/14 (14 steps) 

 

6.10.4 White Line (Displaying the white line on the bottom surface) 

The white line feature allows you to discern between the bottom 

and a school of fish, i.e. the bottom profile is drawn in black and   

white line and the school of fish is displayed in a variety of colors   

without any effect. 

Initial setting: OFF 

Available setting: OFF and ON 

 

 

 

 

 

6.10.5 Pulse Width (Changing the output pulse width) 

According to your requirement, you can change the transmission pulse width in 3 steps.   

S (Short): The definition of fish echoes improves, however, the detection capability lessens. 

M (Medium): The fish echo detection capability improves; yet the image definition is maintained. 

L (Long): The fish echo detection capability increases, however, the image definition will lessen. 

Initial setting: M 

Available settings: S, M and L 

 

NOTE:

 

An alarm beeps when attempting to erase the last remaining color.
