When you change the Ping Speed to any setting greater than 50
percent, the unit automatically enters HyperScroll mode.
These faster ping rates allow you to maintain a high-detail picture on
the screen. It also allows the screen refresh rate and chart scroll speed
to keep pace with the boat as it moves quickly over the water.
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. 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.

When you boost ping speed and switch into HyperScroll, the width of
the FasTrack bar graph display doubles at the right side of the screen.
This allows you to see virtually instantaneous sonar returns, just as
you would on a flasher sonar unit. For more information on FasTrack,
see its entry in this section.
