At left, Map Page showing boat cruising Puget Sound, Washington,
with Overlay Data turned on. This example shows Depth, Ground
Speed and the Steering Arrow. Note that the Steering Arrow always
points directly to the destination you are navigating toward. In this
case, the boater is headed on a northwesterly course of 275º. Since the
helmsman is on course, the Steering Arrow is pointing straight ahead.
If the helmsman veered off course, the arrow would show which direc-
tion to steer to get back on course toward the destination. At right,
Sonar Page with Overlay Data turned on. This example shows Depth,
Ground Speed and the Track the boat is following.
NOTE:
Some data types can be displayed in only one font size. If that is the
case, the Data Size box will not be displayed for that data type.
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.
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, and the screen refresh rate and chart scroll speed can keep
pace with the boat as it moves quickly over the bottom terrain.
