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 automatically 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 percent, the unit automatically enters HyperScroll mode.
