Ping Speed & HyperScroll



Ping Speed controls the rate at which the transmitter and transducer
broadcast sonar sound waves — pings — into the water. The unit has a
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.
