Sonar chart with Overlay Data turned on. This example shows
Depth, Water Temperature and the Ground Speed of the boat.
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.
But when you are running at high speeds or just want the fastest pos-
sible 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 high-detail picture on
the screen.
