default ping speed of 50 percent. At normal boating speeds, this auto- matically provides enough return echoes to refresh the screen and scroll the chart at maximum chart speed.
However, when you are running at high speeds, or just want the fastest possible screen update, you may want to use the HyperScroll feature. When you change the Ping Speed to any setting greater than 50 per- cent, the unit automatically enters HyperScroll mode.
These faster ping rates allow you to maintain a
When using HyperScroll, you may also need to manually decrease the sensitivity for optimum performance. Depending on water depth and other conditions, HyperScroll may cause a second bottom echo to return to the transducer during the next ping cycle, or sounding. This can result in a large amount of clutter appearing on the screen. If this occurs, just decrease the sensitivity to a level that eliminates the clutter. When you turn HyperScroll off, you can return to your original sensitivity level.
