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 280º. 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.

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.
