over the face of the transducer, even vibration from the engine. In all
cases, noise can produce unwanted marks on the display.
The ASP noise rejection feature is especially useful because it typically
lets you operate the boat at all speeds without adjusting the sensitivity

The ASP feature has three settings — Off, Low and High. When first
turned on, noise rejection is set on low. 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 ASP off. This allows you to
view all incoming echoes before they are processed by the ASP feature.
