Noise Rejection and ASP
The ASP
 (Advanced Signal Processing) feature is a noise rejection
system built into the sonar unit. It constantly evaluates the effects of
boat speed, water conditions and electrical interference and automati-
cally gives you the best display possible under most conditions.

undesired signal. It is caused by electrical and mechanical sources such
as bilge pumps, engine ignition systems, wiring, air bubbles passing
