™ (Advanced Signal Processing) 

The ASP

™ feature is a noise rejection system built into the sonar unit 

that constantly evaluates the effects of boat speed, water conditions 

and interference. This automatic feature gives you the best display pos-

sible under most conditions. 
The ASP feature is an effective tool in combating noise. In sonar terms, 

noise is any undesired signal. It is caused by electrical and mechanical 

sources such as bilge pumps, engine ignition systems and wiring, air 

bubbles passing over the face of the transducer, even vibration from the 

engine. In all cases, noise can produce unwanted marks on the display. 
The ASP feature has four settings — Off, Low, Medium and High. If 

you have high noise levels, try using the "High" ASP setting. However, 

if you are having trouble with noise, we suggest that you take steps to 

find the interference source and fix it, rather than continually using 

the unit with the high ASP setting. 
There are times when you may want to turn the ASP feature off. This 

allows you to view all incoming echoes before they are processed by the 

ASP feature.
